Abstract
A process and apparatus for the treatment of hides and skins (3). The hide or skin is placed on a support (1, 2) and sealed to the support around the edges of the skin or hide. A treatment liquor is then supplied under pressure between the skin or hide and the support to distend and stretch the skin or hide to permit the more rapid penetration of the treatment liquor into the skin or hide.

A process for the treatment of skins or hides, comprising the steps of:
- providing a frame having a sealing member corresponding to the profile of the skin or hide;
- positioning the skin or hide on the frame with the flesh side adjacent to the frame;
- sealing the edges of the skin or hide to the frame with an open sealing frame;
- and
- applying treatment liquor under pressure between the skin or hide and the frame, whereby the skin or hide is distended and stretched by the liquor under pressure to open the structure of the skin or hide to permit penetration of the treatment liquor into the skin or hide.
An apparatus for the treatment of skins or hides, said apparatus including a frame having floor, a profiled sealing member on said floor corresponding to the profile of the skin or hide, an open sealing frame to seal the edge of the skin or hide on the profiled sealing member, and means to supply pressurised treatment liquor between the floor and the skin or hide to distend and stretch the skin or hide and thus assist in the passage of the liquor through the skin or hide.
