<p>The invention provides an apparatus and a method for closing or sealing a flexible tubular conduit from within the conduit and has been 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, which preferably comprises a sealing gun (10), has an elongated member or barrel (12) having a mouth (22) at an operative end which is inserted into the conduit. Suction is applied through an air line (56) to the mouth to draw a flap of the conduit into the mouth. A stretched elastic ring (80) carried on a ring supporting means (12, 86) about the barrel is released by ring releasing means (82) to pass over the mouth and flap to contract about the flap and close or seal the conduit. The mouth (22) is preferably annular and closable to clamp the flap while the ring is being released.</p> |
