Abstract
An improved device for leather processing comprising a vessel containing perforated dummy doors and compartments with pegs as well as friction disk fixed along the exterior periphery of the vessel. The leathers to be wet processed are subjected to mechanical action in terms of both rocking action as well as rotational movement simultaneously. The perpetual motion of the device help to create pressure generation for quickening the process and for addition of chemical solution continuously. The processing takes place under pressure generated inside the vessel and with the support of multiple mechanical actions, resulting in higher exhaustion of bath with less processing time and energy requirement and higher capacity utilization to produce good quality leather.
