    The invention relates to a device for laying fiber slivers miteiner deflection guide for the slivers from perpendicular to the deflection axis nebenei¬ergerged, in the pressing direction resiliently supported pressure rollers for Bandum steering and with a displaceable in the direction of view rack for receiving the pressure rollers.
    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 The slivers, which comprise a Kle¬beband carrying a fibrous layer, are withdrawn from a supply roll in the amount of Vorschubbewe¬gung the laying head and fed to the deflection guide, on the one hand press the fiber layer to the already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 which occurs when the fiber slivers are pressed against the fiber layers already laid between the pressure slats 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 slats 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.
    Based on a device of the type described above, the invention achieves the stated object in that the pressure rollers in circumferential bearing receivers engaging, mutually and between lateral guide stops axially guided pulleys formed by means of elastic endless trains, which are guided by a mounted in lateral brackets bearing roller , Are held in bearing engagement with the bearing mounts, and that the bearing mounts independently aufei¬nander in Andrückrichtung resiliently supported on a provided between the lateral supports abutment.
    The provision of pulleys, which are held by means of elastic endless tracks in bearing receptacles, which lead these pulleys over a Um¬ receiving portion, there is no need for storage of the pulleys on a shaft, so that no bearings for such axles are required. Thus, the design conditions are created to be able to select the diameter of the Rillenschei¬ben independently of a groove disks receiving axis. Nevertheless, the possibility of resilient support remains in Andrückrichtung, because yes, the bearing mounts themselves are independently supported in Andrück¬ direction resiliently on an abutment, which is provided between lateral mounts. In addition to the radial guidance of the pulleys on the bearing mounts but is still provide for a corresponding axial guidance. For this reason, the laterally guided Rillenschei¬ben be taken between lateral guide stops that define the axial position of the pulleys, without preventing their radial displacement. The elastic endless trains, with which the spectacle disks are held individually in bearing engagement with the bearing receptacles, must have a sufficient expansion behavior in order to be able to ensure the displacement of the grooved disks in the context of the pretensioning of the resilient support of the bearing receptacles. The device according to the invention thus has a deflection guide for the fiber ribbons, which benefits from the advantages of pressure rollers, without having to accept their disadvantages.
    Particularly advantageous guiding conditions result for the pulleys when the bearing receivers aufwei¬sen in the pulleys engaging rolling elements, because in this case an axial guide component can be applied to the pulleys on the rolling elements.
    The lateral guide stops for the pulleys can also be used to press the fiber sliver against the fiber layers already laid, if the pulleys are combined to form individual pressure elements between pressure disks, which have a sliding surface curved in correspondence with the pulleys for belt deflection and the lateral ones Form guide stops, wherein the laterally arranged on the pressure elements mounts engage in Andrück¬ direction displaceable in recesses of the pressure plates. These recesses in the pressure lamellae are required in order, on the one hand, to be able to connect the pressure lamellae directly axially to the pressure elements formed from the individual pulley disks and, on the other hand, to ensure mutual displacement of the pressure lamellae and the pressure elements in the pressure direction. In order to place particularly thicker fiber ribbons on the already laid fiber layer, the pressure elements and the pressure plates can be displaceably mounted in a frame in the pressing direction in order to pressurize the printing elements and the printing plates independently of each other via a common membrane with a pressure medium can.
    Form the pressure plates in the pressure direction resilient, separated by the recesses of the rest of the lamellae sliding shoes, so can be dispensed with an individual loading of the individual pressure elements and pressure plates, because due to the possible, the resilient bias of the pulleyscomparable resilient bias of the shoes the sliding blocks in Rah¬men Their elastic bias can follow the surface course of already laid fiber layers without having to relocate the pressure plate itself.
    In order to obtain a finely graduated subdivision of the sliding blocks of the pressure lamellae, which is adapted to the pulley disks, the sliding shoes can be subdivided into sliding segments which are parallel to one another on the lamellar plane and which are independent of one another.
    In the drawing, the subject invention is shown, for example. It shows
    1 shows a device according to the invention for laying fiber slivers partially in the region of the deflection guide for the slivers in a simplified longitudinal section,
    2 shows this device in a section along the line II-II of FIG. 1 in a larger scale,
    Fig. 3 is a representation corresponding to FIG. 1 a design variant of a device according to the invention and
    Fig. 4 is a section along the line V-V of Fig. 3 on a larger scale.
    According to the exemplary embodiment according to FIGS. 1 and 2, 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 rollers in the form of pulleys 6 which abut each other and are guided axially between the guide stops 7. The pulleys 6 engage in bearing receivers 8, which are provided with the pulleys 6 via their grooves leading rolling elements 9. For radial fixing within the Lageraufnah¬men 8, the pulleys 6 are supported by a flexible endless train 10 against a bearing roller 11, which is mounted in lateral, as shown in FIGS. 1 and 2, the Füh¬rungsanschläge holders 12 so that the guided axially between the guide stops Pulleys 6 are held in the radial direction via the elastic endless trains 10 and the bearing roller 11 in engagement with the Lageraufnah¬men 8. The bearing receivers 8 themselves are resiliently supported in each case via Federele¬mente 13 in the pressing direction on an abutment 14, the zwi¬schen the lateral brackets 12 are arranged.
    Since the lateral holders 12 are fastened to a pressure element 15 and the pressure element 15 according to FIG. 1 is fixed in a frame 16 so as to be non-displaceable, when the frame 16 is acted upon by a corresponding pressing force, the pulleys 6 are subjected to a resilient biasing of the spring elements 13 is applied to the fiber layers 5, so that the respective guided around the Rillenschei¬ben 6 sliver 2 is pressed against the fiber layers, before the adhesive tape 4 is deducted from the pressed onto the already laid fiber layers 5 fiber layer 3. The individual pulleys 6 can therefore be independent of each other in the context of Vorspann the associated spring elements 13
    Pressing be displaced, which allows a fine adjustment of the Umlenkfüh¬ tion 1 to the surface course of the already laid fiber fabric.
    In contrast to FIGS. 1 and 2, according to the exemplary embodiment according to FIGS. 3 and 4, the guide stops 7 are not formed by the lateral filter grooves 12 but by separate pressure fins 17, the individual pressure elements 15 with pulleys 6 corresponding to FIGS 1 and 2 are slidably received between them in the direction of travel. For this purpose, the pressure fins 17 are provided with recesses 18 into which the lateral filters 12 engage with a corresponding movement play in the pressing direction, so that the lateral filters 12 can not impair the axial guidance of the pulleys 6 between the pressure fins 17 as guide stops 7. By arranging the pressure elements 15 with the pulleys 6 between pressure lamellae 17 with the belt pulleys sliding surfaces 19 adapted for the belt deflection, the pressure lamellae 17 and the pressure elements 15 can be acted upon independently of each other via a common membrane 20 by a pressure medium. For this, the pressure lamellae 17 and to store the pressure elements 15 displaceable in the pressing direction in the frame 16, as can be seen in FIG. 3, in which the membrane is designed in the form of a pressure hose 21, on the pressure lamellae 17 and the pressure elements 15 opposite Um¬fangsseite at one Rack wall 22 is supported.
    However, such individual pressurization of the pressure fins 17 is not mandatory if the pressure fins 17 form a sliding shoe 19 resulting Gleitschuh 23, which is connected via a resilient web 24 with the rest of Lamellenkörperverbunden and therefore acted upon in the pressing direction corresponding to the pulleys 6 miteiner a resilient bias can. Thus, the sliding shoe 23, which at the same time serves as a lateral guide stop 7 for the pulleys 6, as the pulleys 6 are individually tracked the surface course of the already laid fiber layers 5 in the direction of laying, so that under certain circumstances, a separate pressurization of the individual pressure fins 17 and pressure elements 15 is unnecessary.
    The sliding blocks 23 of the pressure lamellae 17 can be subdivided by slits 25 which are parallel to the lamellar plane into slide segments which are spring-loaded independently of one another, as is indicated in phantom in FIG. In this way, even in the area of the pressure lamellae 17, a fine-level tracking of the sliding shoes 17, which is similar to the pulley disks 6, following in the laying direction, is possible.
    The provision of rotatably mounted pulleys 6 reduces the frictional resistance due to the band deflection around the deflecting guide 1. In addition, this frictional resistance can be reduced when the bearing roller 11 for the elastic endless pull 10 shown in Fig. 1 is driven by a shaft 26, which drives the pulleys accordingly about the endless train 10 brings with it.
