ABSTRACT:
The tanning of hides or skins using chromium salts is carried out in a tanning drum by using a total liquid phase less than or substantially equal to the amount of liquid imbibed in the hides or skins in the pelt state. Lubricants can be added to reduce friction between the skins and hide, and between the skins and hides and the drum. An absorbent such as wood flour can be added to absorb residual bath solution.
