Problems solved by technology

The problem here, however, is that the number of filament bundles that make up the bundle changes due to the breakage of the filaments within the bundle, both at the start of the process and in the event of a failure.
It is thus the case that the tow consists of only a small number of individual filament bundles and thus is not suitable for further processing on the fiber production line

Embodiment Construction

[0030] A first embodiment of the device according to the invention for carrying out the method according to the invention is schematically represented in FIG. 1 .

[0031] The device has a spinning device 1, a drawing device 2, a laying device 3 and a creel 4, which are arranged in layers relative to one another. The can creel 4 arranged on the lowermost level has a plurality of cans 5 which are alternately filled with tow 6 by means of a depositing device 3 arranged movably above the can creel 4 . For the melt spinning of a large number of monofilament bundles which are combined into a tow, the spinning device 1 comprises a plurality of spinning positions. In the exemplary embodiment according to FIG. 1, five spinning positions 12.1 to 12.5 are shown by way of example. The number of spinning positions is exemplary. Spinning units of this type may have 20, 30 or more spinning positions for making tows. Each spinning position has a spinning pump 13, which is connected via a ...

Abstract

The invention relates to a method and device to manufacture and store wire beams. Plenty of single wire beams are manufactured by parallel abreast spinning and pumping of polymer melts and form wire beams. The wire beams are continuously located in canisters of frame by transportation mechanism, and fills the canisters in order. In order to reliably received unqualified wire beams in beginning or ending of the process, a waster canister is located on the frame.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for producing and storing a tow as well as a device according to the preamble of claim 9 for carrying out this method. Background technique [0002] Such a method and a device are known from the international patent application WO 2005 / 078172 A1. [0003] In known methods and devices, the cans of the can creel are filled by means of a movable depositing device with a movably guided conveying mechanism for the production of staple fibers in a two-stage process. In this case, the conveying mechanism continuously conveys the strands, so that a large number of melt-spun monofilament strands are withdrawn from a spinning device. In the spinning unit, strands of filaments are spun and drawn from the polymer melt parallel to each other. For laying in the cans of the can creel, all the monofilament bundles are combined into tows and fed together to the conveying mechanism. To fill a can ...
