  • Opening unit for open-end spinning machines
    Patent number: 4471607
    Abstract: In an opening unit for open-end spinning machines, which comprises a housing and a roller lined with sawtooth wire and rotatably arranged in the housing for separating the fibers along their path from the inlet to the outlet of the opening unit, a dirt separation duct is provided in the housing and is maintained under a reduced pressure. In the wall of the housing adjacent at least one side of the dirt separation duct a parallelizing element is inserted which comprises a plurality of saw tooth wire sections arranged in a side-by-side relationship and serving to balance the adverse effect of the dirt separation duct on the parallel flow of fibers on their path through the opening unit.

  • Method of making a beater roll
    Patent number: 4272865
    Abstract: The invention relates to the method of making a beater roll comprising a body and a saw tooth wire helically fitted to the surface of the body wherein the helical convolutions are in spaced relation and wherein a sealant is employed to seal repetitive gaps or spaces between the base of the wire and the smooth cylindrical surface of the beater roll, such repetitive spaces or gaps being caused by placing the set necessary to accommodate wire clothing to the cylindrical surface of a roll as used in open end spinning.
