An air-powered apparatus (10) for separating a string of sausages (S) connected by twisted casings (TC) is provided. The apparatus (10) has a first sausage mouth (46) spaced from a second sausage mouth (48) defining a cutting zone (C). Each sausage mouth (46,48) has a slot (54) for receiving a twisted casing (TC) connecting adjacent sausages. A first knife (70) is movably supported in the first sausage mouth (46), and a second knife (72) movably supported in the second sausage mouth (48). A tensioning cylinder (76) has a fixed end and an extendable end connected to the first sausage mouth (46) to move the first sausage mouth (46) relative to the second sausage mouth (48) to stretch the twisted casing (TC). A first cutting cylinder (66) has a fixed end and an extendable end connected to the first knife (70) for moving the first knife (70) into the cutting zone (C). A second cutting cylinder (68) has an extendable end connected to the second knife (72) for moving the second knife (72) into the cutting zone (C) . A first pilot valve (88) is provided where, upon actuation, the first pilot valve (88) delivers fluid to the tensioning cylinder (76) to stretch the twisted casing (TC). A second pilot valve (90) is provided where, in response to the actuation of the first pilot valve (88), the second pilot valve (88) is actuated which delivers fluid to the cutting cylinders (66,68) to immediately sever the twisted casing (TC).
