  • Traverse mechanism
    Patent number: 5048769
    Abstract: A replaceable traverse module for a winder for winding endless filaments comprises a housing resting on a support element provided in the machine. The housing and the element have interengaging parts to form a guide for the module during insertion onto the machine, and which also cooperate to hold the module in a predetermined position relative to the threadline.
    Type: Grant

    Date of Patent: September 17, 1991
    Assignee: Rieter Machine Works, Ltd.
    Inventors: Armin Wirz, Hansueli Maier, Adolf Flueli
  • Chuck structure
    Patent number: 5007595
    Abstract: There are disclosed one-piece chuck structures for use in winding machines and particularly, but not exclusively, for use in high speed winding machines for the take-up of synthetic plastics filament. These one-piece chuck structures comprise a first elongated tubular portion adapted to receive one or more bobbin tubes and a second elongated tubular portion integral with the first elongated tubular portion and of reduced external diameter relative thereto. Bearings cooperate with the exterior of the second elongated tubular portion such that the first elongated tubular portion and the second elongated tubular portion are rotatable about a common longitudinal axis. Also disclosed are hollow bobbin tube-engaging elements as well as double-arm tube-positioning members which can be used with such and other chuck structures.
