    The invention relates to a device for laying fiber slivers miteiner deflection guide for the slivers from nebeneinan¬dergereihten transversely to the deflection axis pressure plates and with a displaceable in the direction of view rack for receiving the pressure plates.
    Laying heads with a deflection guide for the fiber slivers are usually used for producing fiber layers, which are pressed against the already laid fiber layers with the aid of pressure deflection ribs which form these deflection guide forming side-by-side rows. The slivers, which comprise a Kle¬beband carrying a fibrous layer, are withdrawn from a supply roll in the amount of Vorschubbewe¬gung the laying head and fed to the deflection guide, on the one hand press the fiber layer to the already laid fiber layers and on the other hand, the adhesive tape from the fiber layer, which comparatively small deflection radius required. Since the individual fiber layers of the fabric are to be placed close to each other without air inclusions, a corresponding pressurization of the fiber bands by the deflection guide is to be ensured. To die¬sem purpose, it is known (EP 0 371 289 B1), to store a side by side juxtaposed pressure laminations of each other in the pressure direction displaceable in a rack to store and beaufschlag a membrane with a pressure medium, so that due to the flexibility of Membrane the individual Drucklamel¬len also follow an uneven course of the already laid fiber layers.
    In order to reduce the friction arising when the fiber slivers are pressed against the already laid fiber layers between the pressure disks and the adhesive tape of the fiber slivers, it is also known (US Pat. No. 4,351,688 A, US 2007/044922 A1) to pass through the pressure disks To replace pressure rings which are rotatably mounted on slidably guided in Andrückrich¬tung bearing washers. Regardless of whether the pressure rings supported on the spring-supported bearing disks are acted upon by pressure rollers (US Pat. No. 4,351,688 A) or whether the bearing disks are supported on pressure cylinders (US 2007/044922 A1), these pressure rings have the disadvantage that the displaceable pressure rings Storage of their bearing discs comparatively large diameter of the pressure rings conditionally, which adversely affects not only the pressure exerted on the sliver contact pressure, but also on the removal of the adhesive tape from the fiber layer of the slivers.
    The invention is therefore an object of the invention to provide in a device for laying slivers a deflection guide for the slivers, the under favorable friction conditions on the one hand good contact pressure of Faserbänder to the already laid fiber layers and on the other hand, a safe withdrawal of the adhesive tape from the fiber layer allows Danger to run that when removing the adhesive tape, the fiber layer is partially lifted off the scrim again.
    Starting from a device of the type described above, the invention solves the stated object by providing pressure fins with rollers for belt deflection between pressure fins with a sliding surface for belt deflection and that the holders arranged laterally on the pressure fins for the rollers in the pressing direction displaceable in recesses of the pressure fins with Gleit¬ intervene surfaces.
    Since, according to these measures, not the rollers themselves but the rollers for belt deflection pressure plates are acted upon, there are no restrictions with respect to the roller bearing, so that rollers with a correspondingly small diameter can be used with the effect that the sliver with a Advantageous contact pressure can be applied to the already laid fiber layer, without jeopardizing a simple removal of the adhesive tape from the fiber layer. Despite the support of the rollers for the band deflection on the side of the pressure lamellae provided brackets, the width of the pressure plates provided with the rollers can be limited to the roll width, because the side of the pressure plates arranged brackets engage in An¬drückrichtung displaceable in recesses of the subsequent pressure lamellae with the sliding surfaces. The independent Druckbeaufschla¬gung the pressure plates with and without roles on a common membrane istsomit ensured without having to provide a distance between the pressure plates. Although the pressure fins are provided with the rollers between pressure plates with ei¬ner sliding surface for tape deflection, the frictional resistance zwi¬schen the deflection guide formed in accordance with the invention and the slivers compared to known deflection guides with pressure fins without rollers is considerably reduced. Particularly simple construction conditions result in this connection if the rollers are mounted on axles held in holders arranged laterally on the pressure lamellae.
    Be formed by the recesses for receiving the holders for the roles of the rest of the lamellar body remote, resilient in Andrückrichtung Gleitschuhegebildet, so there is the additional advantage that these Gleitschuhe with an appropriate spring bias regardless of the individual Beaufschlag of the pressure lamellae of the respective surface shape of the already formed fiber laminate can follow, which brings particularly advantageous conditions for pressing the sliver largely independent of the local deformation properties of the membrane with it. A further gradation of the pressurization of the fiber ribbons over their width can be achieved by subdividing the sliding shoes of the pressure laminates into slidable segments by slits parallel to the laminar plane. The pressurizing stages formed by the sliding segments each prestressed for themselves make it possible to pressurize the sliver independently of each other in the region of each sliding segment, which allows particularly favorable conditions for applying the fiber layers of the sliver to the already laid fiber layers.
    An effect comparable to the resilient sliding shoes can be achieved for the rollers for deflecting the fiber slivers in that the rollers designed as rill slips are held in radial engagement with bearing supports supported resiliently relative to the holders by means of elastic endless tracks guided around a bearing roller , As a result of the resiliently supported bearing receivers for the pulleys, they can be prestressed via the spring-supported bearing receptacles when the pressure disks are loaded, so that the pulleys can follow the already existing fiber structure independently of each other within the scope of this prestressing. With the help of elastic endless trains, the laterally supporting Ril¬ lenscheiben are held in engagement with the bearing receptacle, wherein the elastic Dehnung these endless trains for the approval of the preloaded Lageraufnahmies possible displacements of the pulleys in the pressing direction erforder¬ is. The bearing mounts are held clamped between the lateral brackets, which thus form an abutment for the spring elements of Lageraufnah¬men.
    Due to the possible resilient bias of both the sliding blocks of the one pressure lamellae and the pulleys of the other pressure lamellae, individual loading of the pressure lamellae can be particularly disadvantageous for thin fiber tapes, which results in simple construction conditions because the individual lamellae need only be combined immovably in a frame , which with a corresponding compressive force for biasing the Gleitschuhebzw. the pulleys is acted upon.
    In order to keep the friction of the pulleys in the bearing mounts low, the bearing mounts can have rolling elements engaging in the pulleys.

    According to the embodiment according to FIGS. 1 to 3, the device has a lifting head with a deflecting guide 1 for slivers 2, which comprise an adhesive tape 4 carrying a fibrous layer 3. These slivers 2 are withdrawn from a supply roll and pressed with the aid of the deflecting guide 1 to the already laid fiber layers 5 of a fiber fabric to be formed, wherein the adhesive tape 4 is subtracted from the fiber layer 3 of the sliver 2, with a comparatively small deflection radius. The deflection guide 1 is composed of a plurality of perpendicular to the deflection axis juxtaposed pressure plates 6 and 7, which are guided displaceably in a frame 8 in the pressing direction and are acted upon by means of a membrane 9 together with a pressure medium. In order to achieve simple design conditions, the membrane 9 is formed in the exemplary embodiment by a pressure hose, which is supported on the frame opposite the pressure lamellae 6, 7 on a frame wall 10 as Widerla¬ger. When the diaphragm 9 is pressurized, the pressure plates 6, 7 are pressed against the fiber layers 5 already laid, the trajectory of the individual pressure blades 6, 7 depending on the surface shape of the fiber layers 5 already laid due to the flexibility of the diaphragm 9.
    In order to reduce the frictional resistance between the adhesive tape 4 and the deflecting guide 1 when the fiber sliver 2 is pressed against the fiber layers 5 already laid, the slats 7 are provided with rollers 11 for the belt deflection. The
    Order is made such that the rollers 11 rotatably support on axles 12, which are held in lateral brackets 13. These brackets 13 are attached by screws 14 laterally to the pressure plates 7, as in particular derFig. 3 can be removed. Since the laterally projecting beyond the pressure fins 7 mounts 13 engage in lateral recesses 15 of the pressure fins 7 zwi¬schen receiving pressure plates 6, with a Verlage¬rungsspiel in Andrückrichtung, the pressure plates 6, 7 in the direction of the bandwidth in Substantially closed deflection surface for the sliver 2 forms without having to spend on an independent displacement in the pressing direction. The deflection surface for the slivers 2 are formed on the one hand on the sliding surfaces 16 of the pressure plates 6 and on the other hand by the rollers 11 whose radius corresponds to the radius of curvature of the sliding surfaces 16 and can be kept sufficiently small under consideration of the respective requirements, because with regard to the roll diameter hardly Konstruktionsbeschränkun¬ conditions are given.
    As the execution of the pressure plates 6 according to the embodiment of FIGS. 4 and 5, the recesses 15 for receiving the brackets 13 for the axles 12 of the rollers 11 can also be used to form a separate sliding block 17 from the rest of the laminar body, which is connected to the rest of the laminar body via a remaining leg 18 the shoe 17 is resiliently supported in the pressing direction. This resilient support of the sliding shoe 17 allows an additional adaptation of the sliding shoe 17 to the Oberflä¬chenverlauf the already laid fiber fabric regardless of the Beaufschla¬gungslage the pressure plates 6 via the membrane 9. From Fig. 5 it can be seen that the pressure plates. 7 1 to 3 can be equipped only with a roller 11 for belt deflection, in contrast to the embodiment according to FIGS. 1, so that the pressure disks 6 and 7 have the same thickness.
    6 and 7, an embodiment is shown, with the aid of a graduated pressurization in the range of the individual pressure plates 6, 7 er¬möglicht to the sliver 2 in smaller increments to the already laid
    To be able to press fiber layers 5. For this purpose, the pressure plates 7 are provided with a plurality of rollers 11 in the form of pulleys, which abut each other and are axially guided between the pressure plates 6. These pulleys engage in bearing receivers 19 which are provided with the pulleys via their grooves leading rolling elements 20. For radial fixing within the Lageraufnehmnahmen 19, the pulleys are supported by a flexible endless train 21 against a bearing roller 22 which is mounted in the lateral supports 13 of the Drucklamel¬len 7, so that the axially guided between the slats 6 Rillenschei¬ben in the radial direction be held over the elastic endless trains 21 and the bearing roller 22 as abutment in engagement with the bearing receivers 19. The bearing receptacles 19 themselves are supported in each case via spring elements 23 in the direction of pressing relative to the holders 13. This means that when the pressure fins 7 are pressurized via the membrane 9, the rollers 11 in the form of the pulleys are pressed against the scrim under a resilient bias of the spring elements 23. The individual pulley discs can therefore be displaced independently of one another in the pressing direction in the context of the prestressing of the spring elements 23 assigned to them, which permits a fine-tuned adaptation of the deflection guide 1 to the surface course of the already laid fiber pulp.
    Similarly, the sliding blocks 17 of the pressure plates 6 can be subdivided into slits 24 which are parallel to the plane of the slat and into sliding elements 25 which are spring-loaded independently of each other, as can be seen from FIG. Thus, even in the area of the pressure lamellae 6, a fine-level tracking of the sliding shoes 17 along the clutch surface becomes possible.
    Since at a respective resilient support the sliding blocks 17 of the pressure plates 6und the rollers 11 of the pressure plates 7 at a corresponding bias depending for each springy follow the surface shape of the already laid fiber layers 5, namely at a corresponding bias regardless of a Ein¬zelbeaufschlagung the Pressure plates 6, 7, can be dispensed in such a case to indi¬viduelle loading of the pressure plates 6, 7, which is considerable
    Design simplifications brings with it. The pressure lamellae 6, 7 need to be clamped fixedly in the frame 8, in order to press the frame to secure the required preload of the resilient sliding shoes 17 and the resilient rollers 11 with a corresponding force against the already laid fiber layer.
