A HOT OR COLD EXTENDING MACHINE AND STRETCHER WITH PAIRS OF STRETCHED ROLLS WITH HELICIDE STRETCHES THAT MUTUALLY INTERPENETATE FOR TREATING TANNED SKINS AFTER DRYING

摘要

The machine comprises a conveyor belt (1) which forward feeds each hide to be treated by engaging the hide between two drums (5-6) which are ribbed in opposite directions in order to operate the tentering and perching of said hide held by a gripper (2), which advances at reduced speed along guides (3) by the action of a drive device (4). The machine is optionally completed by a second pair of drums (7-8) associated to a second drive device (11) and to a second gripper (10), said drums (7, 8) providing for the working of the second half of each hide.
