ABSTRACT:
An apparatus for treating hides or skins with liquids in so-called wet processes, e.g. tanning, drenching, dyeing, etc., includes a liquid-impermeable substrate receiving the hide in inflexible manner and a treatment device tightly applicable to the top of the hide by which the treatment liquid penetrates the hide under pressure. For limiting the operating pressure in the range of approximately 10 bar, and for the effective penetration of the treatment liquids, the treatment device has several juxtaposed liquid supply ducts arranged roughly at right angles to the substrate, which are widened in large-area manner on the underside of the device facing the hide and are arranged thereon in surface-filling manner. Between the underside of the treatment device and the hide is arranged a fine-mesh support and the gap between the substrate, hide, support and treatment device can be substantially tightly sealed to the outside.
