Problems solved by technology

However, this step-by-step threading of the filaments causes an additional deflection of the filaments between the individual placement guides, for which complex equipment is required, which makes the threading operation more difficult

Embodiment Construction

[0031] exist Figures 1 to 3 A first embodiment of the device according to the invention is shown in several operating positions. exist Figures 1 to 3 The side views are shown in respectively, where in figure 1 shows the running state before threading, figure 2 shows the operating status during threading, image 3 Shows the operating state after threading.

[0032]The following description applies to all drawings as long as no particular drawing is referred to. The exemplary embodiment has a false twister 2 with a housing 5 on which three stationary friction spindles 3.1, 3.2 and 3.3 are rotatably mounted. Friction spindles 3.1, 3.2 and 3.3 each protrude with a free end above the top side of housing 5. FIG. A plurality of friction disks are respectively arranged on the overhanging ends of the friction spindles 3.1, 3.2 and 3.3. Friction spindle 3.1 has a plurality of friction disks 4.1, which are held at a distance from one another on friction spindle 3.1. Adjacent f...

Abstract

The method involves fixing three friction spindles to a triangle with multiple overlapping friction disks in the center. A thread (1) is guided on a feed side by an inlet thread guide (19) and on a discharge side by an outlet thread guide (7). A thread reserve is produced before the threading of the thread on the outlet side, where the thread reserve is exhausted before the end of the threading. An independent claim is also included for a device for executing a method for feeding a running thread in a false twist assembly.

Description

technical field [0001] The invention relates to a method for anchoring a running yarn in a false twister and to a device for carrying out the method. Background technique [0002] A method and a device of this type are known, for example, from WO 03 / 014445 A2. [0003] The synthetic filaments are crimped using a false twister which produces a false twist on the advancing filament which after heat setting gives the crimp of the filament, this false twister produces The machine interior is arranged next to several processing units arranged upstream and downstream, wherein the yarn must be passed into the false twisting machine at the beginning of the processing process. [0004] In order to achieve a (certain) twist distribution, such a false twister has at least three friction spindles arranged fixedly in a triangular shape, which have a plurality of friction disks overlapping one another in the center of the triangle. The friction spindles are driven synchronously at high ...
