In the production of chrome leather, a pretreatment of delimed and bated pelts with condensation products not having a tanning action leads to substrates which, without any problems, can be mechanically dewatered and shaved or split and shaved. The properties of the leathers produced therefrom by chrome tanning do not differ from those of leathers which have been conventionally chrome-tanned and shaved.

Process for producing chrome leather

A method for the wet processes in tanneries, e.g. soaking, liming, deliming, bating, pickling and tanning, wherein the liquids or solutions necessary for these processes are injected by high pressure into the hide or skin, and an apparatus for the realization of said method, wherein piston-type shooting devices are arranged in rows and a conveyor is provided receiving the hide or skin conveying it stepwise below the shooting devices and having holding-up members for pressing the hide against the shooting devices while the injection of said liquids or solutions takes place.
