Treatment of leather goods - has frame with boxes sliding on closed rings and with hot air and water vapour blown through them

摘要

The treatment of leather products is for stretching and conditioning them. It has an outer frame that supports two pairs of rails (2,3) in closed parallel and horizontal rings which are at different heights. Open boxes (12) are fixed to trucks that roll on the rails. The boxes can be hermetically sealed by two covers that each have transverse tubes. Air is heated by heating elements between the tubes and is blown through the tubes and round the boxes by fans. Water vapour or atomised water is injected into the air.
