Abstract
A process for increasing the surface area yield of a tanned hide while improving the surface characteristics of leather resulting from the hide, the invention includes the method steps of freezing the tanned hide or splits from the hide followed by mechanical compression of the hide or splits, such as by biaxial rolling or the like, to substantially increase the yield from a given hide. A hide may be frozen in a planar configuration before splitting, the present process contemplating splitting of the frozen hide prior to mechanical compression to increase useable yield. Alternatively, the hide can be conventionally split followed by optional shaving of the splits with the splits then being frozen and subsequently subjected to mechanical compression according to the invention. The present process also includes apparatus for practice of the process and methodology relating to preconditioning of a hide and to the drying of the compressed splits.
