  • Patent number: 8834148
    Abstract: 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.

  • Patent number: 6439498
    Abstract: An apparatus and a method for winding a web of tapes or yarns to a plurality of packages, wherein a plurality of winding positions are arranged side by side on a long side of the apparatus, with at least one package being wound in each winding position. To distribute the tapes or yarns of the web, a yarn guide bar and a plurality of yarn guides are provided, the yarn guides being associated with respective ones of the winding positions. In this process, the web of tapes or yarns is guided above the winding positions in a distribution plane that extends transverse to the long side of the apparatus. The yarn guide bar is movable so as to permit unimpeded access to the winding positions in a doffing plane which is parallel to the long side of the apparatus, to facilitate doffing of the full packages with the aid of an auxiliary device which can be guided in the doffing plane.
