Embodiment Construction

[0024] figure 1 The apparatus shown in includes a frame 1 basically formed by a pair of upper axle carriers 5 and a pair of lower axle carriers 4 , which are interconnected by four vertical guide bars 7 , 8 , 9 . The frame 1 can be moved in a horizontal plane by means of a hand wheel 6 on a rail assembly having two parallel rails 2 and 3 .

[0025] A pair of upper guide plates 10 , 12 and a pair of lower guide plates 11 , 13 are vertically movable on the guide rods 7 , 8 , 9 . The pair of guide plates 10 , 12 can be raised or lowered by hydraulic lifting devices 14 , 15 . Correspondingly, the pair of lower guide plates 11 , 13 can be raised or lowered by the lower lifting devices 16 , 17 .

[0026] In order to ensure the synchronization of said raising and lowering, the pair of guide plates is assigned a pair of gears 21 interconnected by connecting rods, said gears meshing into a pair of toothed rods 22 on either side of the device and thus allowing the parallelism of the g...

Abstract

The invention relates to an apparatus for cross-sectionally shaping a multiplicity of plastics strands guided in parallel alongside one another over at least one rotatable shaping roller (18, 19, 20), in which the shaping roller is provided on its surface with a plurality of encircling shaping recesses which are arranged in parallel and in which the cross section of the plastics strands is shapable in accordance with the cross-sectional shape of the shaping recesses, wherein preferably three shaping rollers (18, 19, 20) of the same type for sequentially shaping the plastics strands are arranged transversely to the running path of the plastics strands, wherein the plastics strands are guided between a pair of two successive shaping rollers (19, 20) on a first side of the plastics strands and a third shaping roller (18), which is arranged, between the first (19) and second shaping roller (20) of the pair of shaping rollers, on the second side of the plastics strands in the running direction of the plastics strands, and the shaping rollers are mounted in lateral guide plates by means of quick-change apparatuses.

Description

technical field [0001] The invention relates to a device for cross-sectional shaping of a plurality of plastic fiber bundles which are guided parallel to one another by at least one rotatable shaping roller. Background technique [0002] Lightweight structural elements made of plastic, such as are often used in the automotive industry or aircraft construction, often contain fiber materials made of glass or carbon in order to save weight while achieving high strength. The fiber material is incorporated into the polymer melt of the plastic material by means of an impregnation device and is then processed as plastic fiber bundles into pellets, granules or ribbons with a defined cross-section, which are processed in subsequent plants and methods, in particular injection molding methods used in the manufacture of lightweight structural elements. [0003] In the simplest case, the cross-sectional shaping or sizing of the impregnated fiber bundle takes place via nozzles with a def...
