  • Patent number: 4802349
    Abstract: A mechanized power assisted apparatus for flattening and stretching wet tanned hides on a smooth flat horizontal bed of a vacuum hide drier preparatory to drying in the course of leather manufacture. The apparatus includes a support holding a squeegee-type slicker element for positioning closely adjacent to a hide-carrying drier bed. The slicker element has a smooth straight edge which is rotatable in a plane parallel to the surface of the plate. The slicker support is associated with a power travel drive system for moving the support in a plane parallel to and spaced from the surface of the hide-carrying bed and over a hide supported on that bed. A power thrust system is associated with the slicker element for moving the element into and out of contact with the wet hide and for exerting force on the slicker element. Spaced apart controls are provided for actuating the power assist systems for manipulating the slicker element over the surface of a hide in simulation of manual hide application.

  • Patent number: 4787221
    Abstract: An apparatus for fleshing fur pelts with two conical poles, on each of which the pelt is positioned with the fur side facing inwardly. A ring is disposed concentrically of one pole. The ring is clamped to the pelt and moved axially of the pole by a piston driven carriage, which mounts the ring, to tension the pelt. The pole is rotated to allow a rotary scraper to flesh the pelt.

  • Patent number: 4745782
    Abstract: An apparatus for removing fat and flesh from the flesh side of a fur comprises a mandrel with a tapered free end portion. The fur to be treated is arranged on the free end portion of the mandrel with its flesh side turned out and in a substantially stretched condition. The mandrel preferably has a polygonal, such as a rectangular, cross-section. The mandrel and the fur arranged thereon is moved in its longitudinal direction through a scraping device comprising oppositely arranged pairs of rollers having scraping edges which combined define a contour substantially complementary to the cross-sectional contour of the mandrel. Thus, the remnants of fat and flesh may be removed from the fur during a single advance stroke of movement of the mandrel in relation to the scraping device, and the treated fur may be stripped from the mandrel during a return stroke thereof.
