A device and a method wind a thread on a winding machine. The winding machine has a spool sleeve and a spool holder, which has two oppositely disposed centering plates, having an adjustable axial distance relative to each other, for tensioning the spool sleeve. The centering plates each have a centering cone which engages in an open spool sleeve end, and an arrester hook for arresting the thread being provided in one of the centering plates. The arrester hook is oriented in the circumferential direction of the centering plate, and the centering plate having the arrester hook contains an outer cone which overlaps the outer diameter of the spool sleeve end. An inside of the arrester hook is formed by a nose-like recess provided in the outer cone.

Device and method for winding a thread

Techniques involve extruding, orienting and winding up a skein of film tapes or monofilaments. In particular, an apparatus has an extrusion installation, a plurality of drawing-off rollers and orienting rollers and a multiplicity of winding positions which are held alongside one another and one above another on an operating side of a frame wall. The winding positions are configured such that the wound packages are kept ready for removal at the frame wall on a doffing side on the opposite side from the operating side. Such an apparatus is able to achieve a material flow that is as continuous as possible during the production of the film strips and monofilaments.

Device for extruding, stretching, and winding a group of film strips

The invention relates to a method and an apparatus for producing a turf yarn for artificial turf. According to the invention, several monofilaments or ribbons are produced from one respective polymer material in two parallel extrusion processes, the turf yarn being formed by combining several monofilaments or ribbons obtained in the first extrusion process with several monofilaments or ribbons obtained in the second extrusion process. In order to improve especially the elasticity of an artificial turf carpet made from said turf yarn, the monofilaments or ribbons obtained in one of the extrusion processes are crimped before being combined, the crimped monofilaments or ribbons and the flat monofilaments or ribbons being produced in parallel next to each other and being joined in a winding station by means of a tie thread.
