  • 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.

  • Patent number: 4894892
    Abstract: An apparatus for processing an advancing warp sheet of yarns is disclosed, and which includes at least one yarn guide reed which serves to maintain a predetermined lateral separation between the individual yarns of the warp sheet. The reed includes a transverse row of pins which define yarn receiving slots therebetween. To facilitate the thread-up of the warp sheet onto the reed, there is provided an elongate support rail which is positioned parallel to and above the row of pins. During the threading procedure, a first portion of the yarns is withdrawn from their packages and transported along the path of travel of the warp sheet through the apparatus. At each reed, the portion of yarns is laid across the upper surface of the support rail, and the yarns are subsequently transferred from the upper surface of the support rail into individual ones of the yarn receiving slots defined between the pins.
