TREATMENT OF HIDES

摘要

Hides are tanned by stretching the hide to open its structure to allow passage of the tanning fluids. The hide is stretched in a frame, and an open chamber is sealed to the periphery of the hide. Fluid pressure within the chamber forces the tanning fluid through the hide. Sensors beneath the hide determine when fluid has pased through the hide. The tanning process is reduced from days to hours.
