Abstract

The present invention relates to a method and an apparatus for producing synthetic staple fibers. Firstly, a plurality of fiber slivers are produced during the melt-spinning process and are laid together as tows in cans. Subsequently, during fiber processing, several of the tows are withdrawn as one fiber tow from cans, crimped and cut into staple fibers. Here, the can with the deposited tow is transported from the deposit station of the melt-spinning process to the can creel of the fiber texturing process. In order to obtain as uniform a fiber quality as possible when temporarily storing the tow in the can, the can performs a linear translational movement for filling and during filling with the tow. For this purpose, the device according to the invention has a conveying element, by means of which the cans are moved linearly in translation for filling and during filling.

Description

technical field [0001] The invention relates to a method for producing synthetic staple fibers / staple fibers according to the preamble of claim 1 and a method for producing synthetic staple fibers according to the preamble of claim 10 equipment. Background technique [0002] For the production of synthetic staple fibers it is known in principle to produce the staple fibers in a two-stage process. Therefore, in the melt spinning / melt spinning process first a plurality of fiber slivers are spun out of the polymer melt and after cooling are assembled / bundled to form a tow (spinnkabel). The tow is deposited in cans for storage at the end of the melt-spinning process. In the second process step, several tows are assembled into a fiber tow (Tow) and drawn, texturized and cut into staple fibers during fiber processing. For this purpose, the tow is withdrawn from several cans simultaneously. Various methods and devices for producing synthetic staple fibers are known in the prior...
