Embodiment Construction

[0027] FIG. 1 shows schematically a first exemplary embodiment of the device according to the invention with several spinning devices 1.1, 1.2...1.n in an enlarged partial view. Here n is a natural number greater than 0. The device comprises several spinning stations P.1 to P.n. In each spinning station P.1 to P.n, a spinning unit 1.1 to 1.n, a drawing unit 2.1 to 2.n and a coiler unit 3.1 to 3.n are arranged one above the other in layers. Each layer is made of a first base plate 13, a second base plate 26 and a third base plate 27, wherein the first base plate 13 is arranged above the second base plate 26, and the second base plate 26 is arranged above the third base plate 27. The spinning device 1.1 to 1.n are arranged above the second bottom plate 26 and constitute a spinning stage 28 . The traction devices 2 . 1 to 2 . n are arranged between the second base plate 26 and the third base plate 27 and form a traction stage 29 . The coiler devices 3 . 1 to 3 . n are arranged...

Abstract

A device and a method for the melt spinning and depositing of a plurality of tows (5.1, 5.2, . . . , 5.n) utilizes several spinning devices (1.1, 1.2, . . . , 1.n) by means of which one of the tows 5.1, 5.2, . . . , 5.n is produced from a filament bundle (4.1, 4.2, . . . , 4.n). Each spinning device (1.1, 2.2, . . . , 1.n) is associated with a respective drawing-off device and a respective can depositing device (3.1, 3.2, . . . , 3.n) so that each of the tows (5.1, 5.2, . . . , 5.n) can be deposited individually in a respective can (19.1, 19.2, . . . , 19.n).

Description

technical field [0001] The invention relates to a device for melt spinning and stacking a multiplicity of filament strands, which has a plurality of spinning devices, drawing devices and coiler devices which each produce a filament bundle from a single filament bundle. It also relates to a method for the melt spinning and stacking of a plurality of tows, in which a plurality of individual tows are spun parallel to one another, each of which is synthesized into a unique tow. Background technique [0002] For the production of short fibers it is known to first spin a plurality of strands from a polymer melt in a first process step, after spinning the strands are combined into strands and stacked as strands in cans. In a second process step the sliver is withdrawn from the can and cut into short fibers by means of fiber cutters after a number of processing stages. [0003] The invention relates to a device for carrying out the first process. In the known device, individual fi...
