Problems solved by technology

According to the proposal of DE 10 2009 022 163 B4, at first the basic disadvantage is that the displacement movement by means of the yarn guide means a greater degree of movement and the yarn guide needs to be carried out more than by means of a movable displacement rake in order to return to the next displacement movement. The shift more time
Furthermore, the release of the yarn from the depressed position cannot be precisely controlled, as desired for a uniform yarn stress within the yarn bundle

Embodiment Construction

[0031] Figures 1 to 5 A somewhat instantaneous recording of the shift progression in a temporally precise sequence is shown. In each of the figures, the upper figure shows a view towards the left conveyor chain 1 and the right conveyor chain 2, but against their running direction 3; In front of the observer in the picture above. The figure below shows the corresponding movement phases in the viewing direction from above; here, the running direction 3 of the two conveyor chains 1 , 2 always extends from top to bottom in the viewing plane. The illustration is schematic and simplified, since the basic procedure, such as laying the yarn layers, is familiar to those skilled in the art.

[0032] All figures show a section through the left conveyor chain 1 and the right conveyor chain 2 in the upper figure. The two conveyor chains 1 , 2 carry fastening hooks 4 , 5 , the vertically extending hook portions of which are slightly bent back toward the conveyor chains 1 , 2 . In the fi...

Abstract

The device has a plate-shaped displacement rake (6) provided with teeth (8), where spacing between the teeth is equal to spacing between fastening hooks (4, 5). A plate-shaped control comb (12) is provided with teeth (14) and arranged over the rake. The teeth of the comb extend at an acute angle to the teeth of the rake. The comb is movable between two switching positions with the rake and parallel to a movement path of the rake. Wires (21) of a wire band are clamped in the rake over the teeth of the rake in one of the positions of the comb and released in the other position of the comb.

Description

technical field [0001] The invention relates to a device for laying layers of yarn on two conveyor chains extending parallel to each other at a distance, which are arranged on a frame, define a laying plane and are arranged inside in their direction of travel. The layers produced between the conveyor chains are conveyed to the next step for processing. Background technique [0002] The term "transversal" means that the thread guide can move perpendicularly, but also obliquely, to the direction of travel of the conveyor chain. A "displacement rake" shall always be a movable displacement rake which moves back and forth parallel to the corresponding conveyor chain. A displacement rake of the basic construction described here is shown, for example, in DE 33 43 048 A1. When the yarn guide has reached the conveyor chain by its transverse movement and the yarn has been guided through the fixed hooks of the conveyor chain, the displacement rake temporarily receives the yarn of the...
