ABSTRACT:
An apparatus and a method for closing or sealing a flexible tubular conduit from within the conduit devised particularly for use in a slaughterhouse for sealing the anal passages of animal, and especially sheep carcasses to prevent their being soiled. The apparatus has an elongated member or barrel having a mouth at an operative end which is inserted into the conduit. Suction is applied to draw a flap of the conduit into the mouth and a stretched elastic ring which is carried on a ring support about the barrel is released by a ring releasing device to pass over the mouth and flap to contract about the flap and close or seal the conduit. The mouth is preferably annular and closable to clamp the flap while the ring is being released.
