Definitions

  • the elements are arranged on axes which are in tandem along the edge of the conveyor and the elements are moved to engage the hide in a sector of a circle the beginning of which lies along a line normal to the direction of movement of the conveyor and has a path extending arcuately to the peripheral edge of theconveyor.
  • the elements at the front of the conveyor rotating in the direction of movement of the conveyor while that in the rear in the opposite direction.
  • the hide is treated with less force and consequently is distorted and destroyed to a lesser degree.
  • the hide has improved quality. This holds true even for hides having very irregularshapes.
  • the hide is worked to a more uniformed degree and a uniform thicknes leather is obtained.
  • the working elements engage the entire surface of the leather so that a regular surface throughout the entire area of the leather is performed. This is most significant with respect to the peripheral portions of the leather and especially the leg parts which prior devices were never capable of being automatically treated in a regular fashion.
