    Suction body for a pneumatically operated fiber compaction device, as well as a spinning machine equipped with it. In a spinning machine and a suction body for a pneumatically operating fiber compaction device (5), disposed after a frame (1) of a spinning machine, two fiber frameworks (4.1, 4.2) are compacted. They transport in the direction of transport of fibers along the suction body (7) and are spun after the compacting device (5) forming a single strand. The suction body (7) has first and second suction grooves (8.1, 8.2), through which air can flow into the suction body (7) when the suction body (7) is in contact with the suction body (7). Active connection with a source of depression (11). Each of the suction grooves (8.1, 8.2) has at least one fiber conductor edge (14.1, 14.2) in which the corresponding fiber framework (4.1, 4.2) is compacted. The two fiber conductor edges (14.1, 14.2) converge towards one another so that the two fiber frameworks (4.1, 4.2) can be connected together. The two suction grooves (8.1, 8.2) are spaced apart from one another. In the intended fiber transport direction, the fiber conductor edge (14.1) of the first suction groove (8.1) ends after the fiber conductor edge (14.2) of the second suction groove (8.2), and a line of extension of the fiber conductor edge (14.2) of the second suction groove (8.2) crosses the fiber conductor edge (14.1) of the first suction groove (8.1) at a crossing point (kp).

    In addition, the fiber compaction device, in which the fiber network during its transport crosses at least one tightening line, prevents a transfer of the spinning twist generated at the spinning point back to the handle. Corresponding fiber compaction devices are shown, for example, in DE 10 2012 106 781 A1, in which a suction body is made of rotating and perforated belts or alternatively with a round suction body in cross section, which is surrounded by a perforated suction cylinder, equally operable. In this document, as well as in DE 10 2007 006 924 A1, it is disclosed how wandering fibers not directly collected by the suction groove can be captured and fed to the fiber network.
    In document DE 10 2007 006 924 A1, as well as in DE 102 36 450 A1, DE 102 18 794 A1 and DE 196 19 307 A1, it is known that two fiber frames are fed by two spool reels when handling, they are transported separately to the compaction device and approach each other in the compaction device. After they have passed the tightening line, the compacted fiber webs gather in a spinning triangle and spin together. In this way, a single strand is not produced, but a twist, while the two lattices of fibers twist together.
    In DE 43 43 437 A1, a fiber network is subdivided into two partial fiber fabrics, compacted and then assembled again before the tightening line. In this way a single strand is produced in the next spinning process. However, it is disadvantageous that in particular in the case of an erroneous division of the fiber network a non-uniform thread is produced or even the spinning process is interrupted.
    In other spinning devices it is provided that the fiber network moves alternately transversely to the direction of operation of the fiber fabric. Here, in particular in the case of a large alternative movement path, there is a problem that the fiber network does not establish sufficient contact with the aspiration groove, since it cannot cover the entire alternative movement path and therefore both must transfer the compacted fiber network in a broadly centered manner to the second tightening line.

    The aim of the present invention is therefore to create an aspiration body or a spinning machine equipped therewith, which is capable of manufacturing a single strand from two frameworks of compacted fibers, and is therefore capable of maintaining a process of stable spinning even in case of loss or stopping of one of the fiber fabrics or in the case of an alternative movement of a single fiber fabric.
    The objective is achieved by means of a suction body, as well as a spinning machine with the characteristics of the independent claims.
    The suction body according to the invention is provided for a pneumatic compaction device of pneumatic operation, arranged after a handle of a spinning machine, for compacting one or two fiber frames, which are transported in the direction of transport of fibers to along the suction body and spin after the compaction device forming a thread. In this regard, the two fiber webs can be fed by two spool reels to two handrails arranged in parallel and then to the compaction device. But it is also possible to divide a stretch of fibers stretched into a handle and then reach the compaction device. During the use and spinning of a single fiber web, this fiber web can pass in an alternative movement from one fiber leading edge to the other fiber conducting edge.
    The suction body has a first and a second suction slot. Through the two suction slots spaced apart from each other, air can flow into the suction body, when the suction body is in active contact with a source of depression. Each of the suction grooves has at least one conductive fiber edge, in which the corresponding one or network of fibers is compacted. The two conducting edges of fibers converge towards each other, that is to say they approach at least partially to each other, so that the two fiber frames can be connected to each other or that the fiber network that moves alternately can jump from one leading edge of fibers to the other leading edge of fibers.
    The suction grooves spaced apart from each other are configured so that, in the direction of fiber transport provided, the leading edge of the fibers of the

    First suction groove ends after the second fiber conducting edge of the second suction groove. An extension line of the conductive fiber edge of the second aspiration groove crosses the conductive fiber edge of the first aspiration groove at a crossing point. By means of the arrangement according to the invention of the suction grooves, one with respect to the other, or with the fiber conducting edges, one with respect to the other, it is caused that the fiber network that is compacted in the second fiber conductive edge is feed the compacted fiber web at the first fiber conductive edge. Next, the two fiber webs are still compacted more closely together on the first remaining fiber conductive edge or at least held together. Consequently, a single fiber web arrives at the tightening line, after which the fiber web can be spun into a single strand. If only one fiber web is used that moves alternately, the fiber web passes during the alternative movement regularly from one fiber conducting edge to the other fiber conducting edge.
    The spinning process is stable with the suction body according to the invention, so that it can even be continued when only one of the fiber fabrics is present, preferably the fiber fabric guided on the first suction groove. This can be used, for example. so that the fiber network of the second aspiration groove temporarily stops in a directed manner to generate effects on the strand.
    It is especially advantageous that the conductive fiber edge of the second aspiration groove overlaps transversely to the fiber transport direction with the conductive fiber edge of the first aspiration groove. The fibers, which after the second aspiration groove move in the direction of transport and no further in the direction of the conductive fiber edge, are thus gripped by the first aspiration groove and integrated into the fiber network. remaining.
    Advantageously during operation of the fiber compaction device, the suction body cooperates with an air permeable fiber transport element at least by sections, in particular a belt or a cylinder, on which the two fiber frames are transported to along the suction body and covering the two suction slots. The fiber transport element is preferably driven by the pressing cylinder that forms the tightening line for the fabric

    of fibers on the suction body. The fibers of the fiber fabric or fiber fabric are placed on the fiber transport element and move along the suction grooves.
    Advantageously, the suction body is a tube in which the suction slots are located. The tube can be extended along several spinning points arranged next to each other of the spinning machine.
    If the suction body has several pairs of two suction slots, then in an especially advantageous way an economical suction body can be manufactured, which can be associated with exact adjustment to several spinning points.
    If the two suction slots are arranged in an insert and the insert is fixed in the suction body, then the suction body can be advantageously provided with different arrangements of suction slots. Depending on the material of the fibers to be spun or the desired strand quality, the suction grooves according to the invention can be configured or arranged differently.
    Advantageously, the two suction slots are spaced apart from each other less than 6 mm, preferably less than 4 mm. Thanks to this distance, it is achieved in a particularly suitable way that the fibers of the second fiber conducting edge can be transferred to the fiber network of the first fiber conducting edge and grasped by it.
    If the two suction slots are spaced apart from each other more than 1.5 times the wall thickness of the suction body, then it is guaranteed that due to mechanical influences the suction body between the two suction slots does not deteriorate, in particular it does not sink and consequently the fiber guidance is impaired.
    If the conductive fiber edge of the first suction groove extends in the direction of fiber transport provided after the crossing point still at least 2 mm, preferably at least 4 mm, then it is ensured that the incorporation of the fiber network of the second conductive fiber edge in the lattice of

    Fibers of the first conductive fiber edge are essentially completely realized. In this respect, loose fibers are widely avoided.
    In a particularly advantageous configuration of the invention, the angle between the intended fiber transport direction and the fiber conductive edge of the first aspiration groove is greater than the angle between the expected fiber transport direction and the fiber conductive edge. of the second aspiration slot. Accordingly, the connection of the two fiber fabrics is particularly suitable, since the second fiber fabric can thus be reliably received by the first fiber fabric.
    Depending on the fiber material and the desired strand quality, the first and / or the second aspiration groove or its conductive fiber edge is set in a straight or curved manner. In this respect, the curvature can be angled or arched. It can be present in only one or also in both suction slots. It is also possible that the conductive edges of fibers are first configured divergently and only at the end of the conductive edges of fibers convergently.
    It is advantageous for the suction groove to have an essentially constant width along the conductive fiber edges. In this way a uniform compaction of the fiber fabrics is obtained,
    If the two fiber conducting edges have a different length, then the first suction groove can be configured as long as possible on the suction body. The fiber compaction can be carried out in this way especially efficiently.
    The spinning machine according to the invention has a plurality of spinning points. Each of the spinning points has at least one handle for stretching one or two strands of fibers fed in the transport direction. The fiber webs can be fed from two reel of lighter or proceed to a reel of lighter and be subdivided into two fabrics of individual fibers if two fiber fabrics are used. After the handle, a pneumatic compaction device for pneumatic operation is arranged. In the fiber compaction device the fibers of the fiber network or of the fibers are compressed

    fiber fabrics. The fiber compaction device has an aspiration body and an air permeable fiber transpose element at least by sections, in particular a belt or a cylinder, on which the fiber fabric or fiber fabric are transported in the transport address
    A torsion device, in particular an annular spinning device, is arranged after the fiber compaction device for spinning the compacted fiber web forming a thread.
    The suction body is covered by the brake transport element. The fiber transport element transports the fiber network or the fiber networks above the suction body and the aspiration grooves contained therein, whereby the fiber fabric or the fiber fabric are applied and compacted against the edges fiber conductors of the suction slots. The two fiber conducting edges converge towards each other, so that, during an alternative movement, the fiber network comes into contact - at least in the direction of the fiber's travel at the beginning of the fiber conducting edge - alternately with one or with the other conductive fiber edge, or the two fiber webs can be connected to each other. The suction body has a first and a second suction groove, through which air can flow into the suction body when the suction body is in active connection with a source of depression. Each of the suction slots has at least one conductive fiber edge, in which the corresponding fiber network is compacted.
    A compressor cylinder presses one or the fiber webs connected together against the transport element and thus constitutes a torsion stop for the spinning device.
    According to the invention the two suction slots are spaced apart from each other. The suction slots spaced apart from each other are configured such that, in the direction of fiber transport provided, the conductive edge of fibers of the first aspiration slot ends after the second conductive edge of fibers of the second aspiration slot. An extension line of the conductive fiber edge of the second aspiration groove crosses the conductive fiber edge of the first aspiration groove at a crossing point.

    Due to the arrangement according to the invention of the aspiration grooves or the conductive edges of fibers with respect to each other, the two fiber webs are connected. Next, the two fiber webs are still compacted even more together at the first remaining fiber conductive edge or at least held together. Consequently, a single fiber web arrives at the tightening line, after which the fiber web can be spun into a single strand.
    The suction body of the spinning machine according to the invention is carried out in accordance with the characteristics described above.
    It is especially advantageous for the first suction groove to end closer to the compressor roller or tightening line than the second suction groove. In this regard, the second aspiration groove may end at or shortly after the tightening line or also shortly before the tightening line. The optimum location of the end of the suction groove depends essentially on the material of the fibers and the quality of the yarn to be obtained.
    Other advantages of the invention are described in the following examples of realization. They show:

    Figure 6 a plan view of a suction body according to the invention with a rectilinear suction groove and a curved and a single fiber network that moves alternately.
    Figure 1 shows on the right side first the outlet area of a handle 1, as used among others in ring spinning machines, as an example of a spinning machine according to the invention. The pair of outlet cylinders of the handle has an upper outlet cylinder 2 and a lower outlet cylinder 3. A fiber network 4 circulates through the hose 1 and a fiber compaction device 5 adjacent to the handle 1. To ensure the guided of the fiber network 4, in the handle 1 the upper output cylinder 2 is pressed against the lower output cylinder 3. This is why a clamping line KL1 is present in whose area the fiber fabric 4 is correspondingly tightened and by means of the rotation of the lower output cylinder 3 and with that of the upper output cylinder 2 is transported in the direction of the subsequent compaction device 5.
    The fiber compaction device 5 has a compressor cylinder 6 that presses on a suction body 7, which is configured here in the form of a suction tube. The suction body 7 has a suction groove 8 that extends between the pair of outlet cylinders of the handle and a clamping line KL2 between the compressor cylinder 6 and the suction tube 7. Between the compressor cylinder 6 and the body of suction 7 a fiber transport element 9 is located, here in the form of a belt, which is guided around the suction body 7 and around a deflection point. The compressor cylinder 6 is connected by virtue of the drive with an upper outlet cylinder 2 and thus drives the belt 9 and the fiber web 4 in the direction of fiber transport and thereby transports the fiber web 4 from the handle. 1 to the compaction device 5 and the spinning device. The belt is air permeable, for example perforated, or has air permeable meshes in the manner of a sieve. In this way a depression can act through the suction groove 8 and the belt 9 on the fiber network 4. The depression in the suction body 7 is generated by a source of depression 11, which is connected to the body of aspiration 7.
    The tightening line KL2 forms a torsion stop for the fiber network 4, which is fed to a device after the fiber compaction device 5

    of torsion, for example, an annular spinning device. The torsion from this torsion device stops at the tightening line KL2 and thus achieves a network of fibers 4 widely without torsion in the area of the suction groove 8.
    Another embodiment of the present invention is shown in Figure 2. The representation shows in this area a pair of cylinders per belt that have two handle belts 13 for guiding a network of fibers 4 to be compacted. Next, the pair of belt cylinders follows a pair of outlet cylinders from the handle with the upper output cylinder 2 and the lower output cylinder 3. Between the upper output cylinder 2 and the lower output cylinder 3, the line is present of tightening KL1, in which zone the fiber network 4 is tightened and by turning the pair of output cylinders it is transported in the direction of the subsequent compaction device 5.
    The compaction device 5 has a compressor cylinder 6 and an aspiration body 7. In the aspiration body 7 an aspiration groove 8 is arranged, which Mega up to near or according to the embodiment also below the tightening line KL2. In this exemplary embodiment, the fiber transport element 9 is not a belt, but is configured as a perforated suction cylinder. Between the compressor cylinder 6 and the aspiration cylinder, the clamping line KL2 is again present, in which the fiber network 4 is tightened and constitutes a torsion stop.
    In the example shown. The suction body 7 is circularly configured and its inner zone can be actively connected with a depression source 11 not shown. The suction body 7 also has an aspiration groove 8 oriented in the direction of the fiber network 4, whose geometry and function will be explained in more detail below. The perforated aspiration cylinder prevents aspiration of the fibers through the aspiration groove 8 and due to its rotation acts as a fiber transport element 9.
    If, during the operation of the spinning machine, the fiber network 4 is guided over the suction groove 8, then it is exposed to a suction air flow that finally achieves a compaction of the fiber fabric 4. In relation to the following figures Additional details will be explained in more detail.

    Figure 3 shows a suction body 7 according to the invention, in which two suction slots 8.1 and 8.2 are arranged. The first aspiration slot 8.1 is configured longer than the second aspiration slot 8.2. In each of the two suction slots 8.1 and 8.2, a fiber network 4.1 and 4.2 is fed in the transport direction. The fiber frames 4.1 and 4.2 first cross the tightening line KL1 and Megan then to a conductive edge of fibers 14.1 or 14.2 of the suction slots 8.1 and 8.2. On the conductive edge of fibers 14.1 or 14.2, the fiber frames 4.1 and 4.2 or 4 are compacted. At a crossing point KP there are the two fiber frames 4.1 and 4.2 and they join together forming a fiber fabric 4. After the point of crossing KP, the network of joined fibers 4 crosses the second line of tightening KL2.
    The two suction slots 8.1 and 8.2 are arranged obliquely with respect to the direction of fiber transport and converge towards each other. In the exemplary embodiment of Figure 3, the aspiration slot 8.1 is configured inclined with respect to the direction of fiber transport with an angle greater than the aspiration slot 8.2, which is arranged inclined with respect to the direction of fiber transport with a smaller p angle. The second suction slot 8.2 is arranged at a distance A from the first suction slot 8.1. The distance A is preferably less than 6 mm, preferably less than 4 mm or at least 1.5 times the wall thickness of the suction body 7. This ensures a stable configuration of the suction slot 8.1 and 8.2. In addition, it is ensured that the fiber network 4.2 can be transferred seamlessly to the fiber network 4.1 and can be connected forming the common fiber network 4. It is especially advantageous that after the crossing point KP a length L of at least 2 mm is present, along which the common fiber network 4 is conducted on the fiber conducting edge 14.1. This ensures a reliable connection of the two fiber fabrics 4.1 and 4.2.
    The fiber transport element 9 is arranged on the suction body 7 and on the suction slots 8.1 and 8.2. The fiber fabrics 4.1 and 4.2 or the fiber fabric 4 are placed on the fiber transport element 9.
    In Figure 4 a slight modification of the embodiment of Figure 3 is shown. In this regard the suction slot 8.1 is not configured in a straight, but curved way. In this exemplary embodiment, the suction slot 8.1 is curved

    after the crossing point KP in the direction of fiber transport, so that there is an intense magnet compaction of the 4-fiber network. Obviously, other angled or arcuate arrangements are also possible, both of the aspiration groove 8.1 and also of the aspiration groove 8.2 according to the requirements of thread formation.
    Figure 5 shows another embodiment, in which the suction slots 8.1 and 8.2 are configured in an inverted manner to the previous embodiments. It is possible that in the suction body 7 the embodiment according to this figure 5 is arranged, as well as embodiments according to the previous figures. In this way, the wear of the compressor cylinder 6 can be reduced, for example, while the compressor cylinder 6 is changed in the case of the suction groove according to, for example, figure 3 after wear occurrences and is delivered to the suction grooves according to figure 5. Therefore the wear is performed axially offset, so that the compressor cylinder 6 can be used longer.
    In addition, Figure 5 shows in an indicated manner an insert 15 which is arranged in the suction body 7. The insert 15 contains the suction slots 8.1 and 8.2. Thanks to a replacement of this insert 15 with another insert not shown with another arrangement of the suction slots 8.1 and 8.2, for example, with the suction slots of Figure 4. a retrofitting can be carried out very simply and economically to Other spinning conditions.
    Figure 6 shows a plan view of an aspiration body 7 according to the invention with a rectilinear groove groove and a curved 8.1 and 8.2 and a single fiber network 4 that moves alternately. The embodiment corresponds to the example of figure 4. It is also possible to apply the invention with the examples of realization of the other figures with only a web of fibers 4 that moves alternately. The fiber network 4 moves alternately in the area C transversely to the direction of the fiber network 4. In the whole area C, the fiber network 4 is fed to at least one of the two suction slots 8.1 and / u 8.2. In the central part of zone C, the fiber network 4 jumps from one suction slot 8.1 or 8.2 to the other suction slot 8.2 or 8.1. In the position shown on the left of the fiber web 4, the fiber web 4 circulates on the aspiration groove 8.1 and subsequently on the end of the second aspiration groove 8.2. At
    right edge of the alternative movement zone C, the fiber network 4 shown in strokes only circulates on the second suction groove 8.2. With the device according to the invention, a particularly wide alternative movement of the fiber network 4 is possible, while with only one suction groove 5 a stable spinning would easily be possible.
    The present invention is not limited to the embodiment shown and described. Modifications are also possible within the framework of the claims, as a combination of the features, even when they are represented and described in different embodiments.
