Abstract: A device is described for separating animal skin and for transferring it to further processing through a conveyance channel by using pressure difference. The device comprises a pulling device (3) for separating the skin (2) from the animal carcass (1) and for feeding it to the forward end of a conveyance channel (7), and means (8-10) to generate pressure difference between the ends of the conveyance channel and for separating the conveyed skin (2) form the portage air. According to the invention, the pulling device (3) that engages the other end of the skin (2) further comprises means (4, 5, 12) for feeding the skin (2) to the feed hopper (6) at the forward end of the conveyance channel (7) and for separating it from the pulling device (3) for suction conveyance. In this case, the feeding and separating means (4, 5, 12) are preferably set above the feed hopper (6) so that the skin (2) can be dropped to the feed hopper (6) for the suction conveyance.
