Bur Removers, Gripping Feed Patents (Class 19/84)
  • Patent number: 5455990
    Abstract: Device for cleaning Morel cylinders of a wool card, comprising a tool carrier (1) displaceable along the Morel cylinder (2). The tool carrier (1) is mounted on a carriage (3) displaceable on a tube (4), extending parallel to the axis of the Morel cylinder (2), and comprises at one end a cleaner (5) in the form of a semi-rigid self-cleaning covering and/or rigid steel blades and at its other end a counter-weight (6). The tool carrier (1) is mounted pivotally on the carriage (3) by a shaft (7) fixed on the carriage (3), and the cleaner is flexibly urged against the Morel cylinder (2) by the counter-weight (6). The upper surface of the cleaner (5) is turned toward the Morel cylinder (2) and coacts with the spiral winding of the covering of the Morel cylinder (2) such that the rotation of this latter gives rise to an axial displacement of the tool carrier (1) and of the cleaner (5).

  • Patent number: 5307540
    Abstract: A wool card includes a rotatable Morel roller and first and second burr beaters rotatable relative to the Morel roller and relative to each other and spaced apart about the periphery of the Morel roller. The wool to be carded moves in one direction about the Morel roller and between the first burr beater and the Morel roller and then between the second burr beater and the Morel roller. The first burr beater turns at a lower speed than the second burr beater. The burr beaters have blades thereon which contact the wool to remove impurities from the wool. The number of blades on the first burr beater is less than the number of blades on the second burr beater.
