Abstract

A leather tanning drum consists of a main cylindrical body in polymeric material in which a plurality of cavities, or pockets, are longitudinally arranged along the internal surface of the main body, said longitudinal cavities being connected with other cavities which are provided in one of the cylindrical main body circular surfaces, and being also connected with a hollow shaft communicating with the outside, in such a way that, during the drum rotation around said shaft, both the continuous exchange and the renewing of the chemical bath contained in the drum may take place. A metal framework is externally connected with the cylindrical main body in a way suitable to the thermic dilatations of said main body. At least one door for the introduction and removal of leathers into and from the drum is kept closed by the help of elastic means regulated so as to assure a perfect seal under normal operating conditions and which, at the same time, work as a safety-valve in the event of anomalous increases of the drum internal pressure.
