Embodiment Construction

[0023] FIG. 1 schematically shows the stations of a first embodiment of a texturing machine according to the invention. The frame for fixing the machine base of each processing device is not shown in the figure here.

[0024] On creel 3, fix one and feed bobbin 1. The feed bobbin 1 contains a filament 2 which is drawn off from the feed bobbin 1 by means of a first conveying device 4 . A heating device 5 , a wetting device 6 , a cooling device 9 , a crimping device 10 and a second conveying device 11 are arranged downstream of the first conveying device 4 in the thread path. The filament 2 is fed by a second feed mechanism 11 to a winding device 12 . The filament 2 is wound into a package 15 in the winding device 12 . The winding device 12 is composed of a driving roller 13 , a reciprocating mechanism 14 and a bobbin holder 16 . The mandrel 15 is here driven at a substantially constant speed by means of a drive roller 13 .

Abstract

A texturing apparatus for draw texturing a synthetic yarn. To this end, the texturing machine comprises a first feed system, a heating device, a cooling device, a texturing unit, a second feed system, and a takeup device for winding the textured yarn. Between the heating device and the cooling device, a wetting device is provided for wetting the heated yarn with a cooling fluid for purposes of precooling. The wetting device consists of a rotatable cooling cylinder which includes on its circumference a yarn track that contains a cooling fluid. The yarn can be wetted by contacting the yarn track. At the point of contact, the yarn friction is advantageously dependent on the relative speed between the yarn and the yarn track on the circumference of the cooling cylinder.

Description

technical field [0001] The invention relates to a crimp texturing machine for stretch-crimp texturing of synthetic filaments according to the preamble of claim 1 . Background technique [0002] A texturing machine of this type is known, for example, from EP 0 879 907 A1. [0003] Such texturing machines are used to texturize one or more filaments to produce bulked and texturized yarns from melt-spun smooth filaments suitable for further processing into a knit or textile. For this purpose, the spun smooth filaments are withdrawn from a feeding bobbin, crimped, stretched, and after crimped in a texturing zone comprising a heating device, a cooling device and a texturing device wound onto a reel. In order to improve the cooling effect, a wetting device is arranged between the heating device and the cooling device in the crimping zone, by means of which cooling fluid is applied to the filaments. For this purpose, the filaments are guided in contact with a wetted surface, whic...
