US 4,596,124 A · Power assist hide applicator

Abstract

A mechanized power assisted apparatus for flattening and stretching wet tanned hides on a smooth flat plate preparatory to drying in the course of leather manufacture. The apparatus comprises support means holding a squeegee-type slicker element for positioning closely adjacent to a hide-carrying plate. The slicker element has a smooth straight edge which is rotatable in a plane parallel to the surface of the plate. The slicker support means is associated with a powered travel means for moving the support means in a plane parallel to and spaced from the surface of the hide-carrying plate and over a hide supported on that plate. Powered thrust means are 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 control means are provided for actuating the power assist means for manipulating the slicker element over the surface of a hide in simulation of manual hide application.
