The present invention relates to a spreading machine for roller leather finishing. The machine includes a drawing cylinder and an engraved spreading cylinder. The drawing cylinder acts as a driving roller for a rubber conveyor belt wound between the driving roller and an idle roller. The drawing cylinder has a conveying surface and a rubber layer. In each operating configuration, the conveying surface of the rubber conveyor belt is tangent to the engraved spreading cylinder in a point of tangency (P), and the idle roller has a leather-detachment roller having a diameter within the range of 10 and 80 mm.

A tanning process for tanning of animal hides in a process equipment including a tanning container, a controller, and temperature regulating equipment. The controller controls the temperature in the tanning container based on a temperature setpoint input to or established by the controller. The tanning process includes the steps of initially determining process parameters based on animal hide characteristics including at least animal hide type and animal hide weight. The process parameters include at least one of the parameters: time, temperature, start pH and end pH or any combination thereof. The tanning process of the animals hides is executed based on the process parameters in the tanning container under atmospheric pressure. The tanning process involves the addition of tanning agents to animal hides in the tanning container. The tanning involves the addition of water in an amount of less than 10% bw of the animal hides.
