  • Thread-catching device for winding machines
    Patent number: 4817896
    Abstract: A chuck is adapted to be cantilever-mounted for rotation about a longitudinal axis thereof in a winding machine for threads, such as synthetic plastics filament, glass fiber strands and so forth. The chuck comprises a chuck member and an element movable radially thereat between retracted and extended positions under the action of centrifugal force when the chuck is rotated about its longitudinal axis at or above a predeterminate operating speed in use. The element has a head portion which projects radially outwardly from the bobbin tube receiving surface of the chuck member of the chuck when the element is in its extended position, and is located inwardly of such bobbin tube receiving surface when the element is in its retracted position.

  • Chuck structure
    Patent number: 4811910
    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.

  • Device for feeding a pressure medium into a shaft
    Patent number: 4506692
    Abstract: In order to avoid excessive wear between a sealing ring and a shaft, the sealing ring is provided with a biased sealing lip which is moved against the shaft by a pressure medium flowing into an infeed channel of the shaft. When not in use, the sealing lips are spaced from the shaft and serve to close off the pressure medium chambers of the feed device.In order to exhaust air, the flow of pressure medium is shut off to the feed device so that the sealing lips are sprung back against a projection of the device in spaced relation to the shaft. This permits the pressure medium to exhaust from the shaft through a gap between the shaft and the feed device.
