A system and method for fresh bovine hide splitting includes a hide splitting machine configured to split a fresh bovine hide into a top grain and a collagen sheet. The top grain may be used for leather products. The collagen sheet may be processed with at least one of a maceration process or a drying process to produce a fresh bovine hide raw material product without the addition of a liming or bluing process. The fresh bovine hide raw material product may not include residues remaining following a liming process or bluing process. The fresh bovine hide raw material product may be usable in downstream products for human consumption including gelatin.

The present invention provides a wet leather stretching device, including a second bracket (12) provided with a mechanism for adjusting tension of a first belt (17), wherein the mechanism includes: a movable plate (41) coupled to each of left and right side surfaces of the second bracket (12); a support plate (31) coupled to one surface of each movable plate (41); a cylinder (32) having a lower part fixedly coupled to a lower part surface of each support plate (31); a rod (33) protruding a certain length through an upper part of each cylinder (32); a guide end (35) provided on one surface of the movable plate (41) at a distance above the support plate (31); a guide plate (36) connected to the rod (33) and contacting with the guide end (35), and a movable pipe (37) with a predetermined length contacting with the first belt (17).

An elongated pelt board for accommodating an animal pelt. The pelt board defines a blunt end and an opposite pointed end and a longitudinal direction. The pelt board further defines a first radial direction perpendicular to the longitudinal direction and a second radial direction perpendicular to the longitudinal direction and the first radial direction, said pelt board comprising a first part at said blunt end and an opposite second part at said pointed end. The first part comprises a first wall element and a second wall element. The first and second wall elements are of identical configuration. The first wall element and said second wall element define a contracted state and an expanded state.
