Problems solved by technology

However, it can often be noticed that the relaxation does not take place uniformly, but rather, so to speak, in jumps, which leads to an uneven (unsauber) fabric appearance (Warenbild) or streaks (Streifenbildung)
Both lead to reduced quality of the fabric web

Embodiment Construction

[0021] The figure schematically shows a textile machine 1 , for example a warp knitting machine, which produces a textile web 2 in the form of a knitted fabric. The textile web 2 is a highly elastic textile surface in which highly elastic threads are processed while being stretched. The width of the textile web 2 at the outlet of the textile machine 1 is determined by the production process and by the production width. During production, the textile web 2 is thus kept in the required width by the weaving machine 1 .

[0022] After leaving the textile machine 1, however, there are practically no longer any forces against the relaxation of the fabric web 2, ie the shrinkage transversely to the production and travel direction of the fabric web 2. As soon as the textile web 2 leaves the weaving machine 1 it therefore tries to reduce its width.

[0023] The textile web 2 is withdrawn from the textile machine 1 via a withdrawal device 3 . In the present exemplary embodiment, the ...

Abstract

The present invention relates to a device for drawing a fabric breadth(2) of a surface-shaped textile from a textile machine(1), especially tricot machine. The device is provided with a plurality of leading-out rollers (4-6), the breadth path of the textile breadth (2) is extended on the surfaces of the leading-out rollers (4-6),and the breadth path is led to a textile accommodating piece (15) in the processing direction after passing the leading-out rollers (4-6).The device is expected to convey textile breadth of elastic textiles with high quality. Clamping equipment is arranged on the last leading-out roller (6) of the processing direction, and a clamping clamp (9) is formed by the clamping equipment and the leading-out roller (6),and the breadth path is extended through the clamping clamp (9).

Description

technical field [0001] The invention relates to a device for drawing out (abziehen) planar (flächig) woven (textil) fabric webs (Warenbahn) from a textile machine, especially a warp knitting machine (Kettenwirkmaschine), with a plurality of take-off rollers (Abzugswalze), on whose surface runs the web path (Bahnpfad) of the fabric web, which leads to the fabric holder in the direction of travel after the take-off roller. Background technique [0002] The highly elastic textile surface is produced at a defined production width on a corresponding textile machine, for example a warp knitting machine. During production, the elastic thread (Faden) is processed under stretching (Verstreckung). This stretching brings about a pretensioning of the woven fabric web transverse to its direction of travel or withdrawal. Therefore, as soon as the fabric web leaves the weaving machine and no longer remains at the production width, the fabric web tries to relax into the unloaded state. ...
