  • Patent number: 4885823
    Abstract: For the formation of fleeces or webs with parallelized, hooklet-free fibres for pattern production or for spinning mills, a raw material undergoes preliminary drawing in a preliminary drawing frame and is then supplied to a feed arrangement, through which the raw material is supplied to a clamping point of an extracting device formed of two clamping rollers. The clamping rollers running at a higher speed than the feed speed of the feed arrangement pull out fibre tufts disentangled and parallelized on one side. Then the tufts are fed to a suction drum for doubling purposes. From the suction drum the web formed with one disentangled side is fed into a further preliminary drawing frame, into a second feed arrangement, then into a further extracting device and thereafter into a further suction drum.

  • Patent number: 4827781
    Abstract: A method and apparatus for extracting a fiber sample from a sliver of material for fiber length measurement in which the sliver is successively advanced into and retained by needles in a sample extracting position with the fiber end of the sliver exposed for sampling. The end is then grasped by a clamping member which moves away from the retained sliver to extract the sample. The retention of the sliver is synchronized to follow the advancement of the sliver to its sample extracting position and the movement of the clamping member is synchronized to occur during the retention of the sliver by the needles in this sample extraction position.
