In addition, this results in the problem of an inhomogeneous liquid distribution over the width of the tow, since the vibration of the squeezing tool in the squeezing device and thus the risk of inhomogeneity in the roll gap increases

[0033] exist figure 1 A first exemplary embodiment of an apparatus according to the invention for carrying out the method according to the invention for processing tows for the production of staple fibers is schematically shown in side view. The apparatus has a plurality of processing devices which are successively arranged to form a fiber production line in which the direction of travel of the tow is between figure 1 Indicated by arrows.

[0034]At the beginning of the fiber production line there is a drawing device 2 on which a plurality of drawing rollers 20 are arranged to advance the filaments. The tow 1 , which consists of a plurality of strands of synthetic monofilaments, is guided in the form of a belt on a take-off roll 20 . Synthetic monofilament strands are drawn, for example, from can creels with a large number of cans. Each of the cans contains a tow-like monofilament sliver with a large number of individual monofilaments and laid down in a tow at the end of th...

Abstract

The invention relates to a method for treating a fibre cable for the production of stacked fibres and to a device for carrying out said method. The fibre cable is drawn in a drawing zone before being cut into stacked fibres, wherein the fibre cable is treated with a fluid prior to the drawing process. After drawing, the fibre cable undergoes a thermal treatment in order to immobilize the fibre material, the fluid contained in the fibre cable before the thermal treatment is reduced by pinching the fibre cable. In order to adjust the fluid content in the fibre cable to the respective treatment stages, the fibre cable is already pinched within the drawing zone over its width to such an extent that an evenly distributed proportion of weight of <10 % of the fluid is achieved over the width of the fibre cable. For this purpose, the device comprises a pinching device which is arranged within the drawing zone and provided with flexurally rigid pinching means.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for processing tows for the production of synthetic staple fibers and a device according to the preamble of claim 9 for carrying out the method. Background technique [0002] A method and a device of this type are known from US Pat. No. 6,203,743. [0003] In known methods and devices, the tow made of a large number of synthetic monofilament strands is first guided through a moistening device in the form of a immersion bath after being withdrawn from the can creel, so that all fiber strands are uniformly moistened, And thus a reliable incorporation of the individual fibers is obtained during processing. The liquid is preferably used here as an oiling agent, which enables the tow to be reliably advanced on the processing device of the fiber production line. Furthermore, the liquid within the tow results in a substantially good, uniform heat transfer and movability of the individual...
