5 Claims.

1. An apparatus comprising a knife holder having a central passage through which a frozen pork sausage encased in a cellulose casing is to be passed, a plurality of equidistantly spaced knives pivotally mounted in said holder with their cutting edges disposed in spaced relation to each other in said passage to cut the casing of the sausage passing therebetween, means to maintain said knives under tension sufficient to cut the casing without substantially scoring the meat mass, a center guide tube, means attaching said knife holder to one end of said tube with their longitudinal center axes in alignment whereby a sausage passing from the zone of action of said knives will directly enter said tube, and means to supply steam to the interior of said tube.

3. An apparatus comprising a knife holder having a central passage through which a frozen pork sausage encased in cellulose casing is to be passed and a plurality of slots spaced equidistantly about said central passage, a knife pivotally mounted in each of said slots, said knives having their cutting edges disposed in spaced relation to each other in said passage to cut the casing of the sausage passing therebetween, means to maintain said knives under tension sufficient to cut the casing without substantially scoring the meat mass, a center guide tube, means attaching said knife holder to one end of said tube with their longitudinal center axes in alignment whereby a sausage passing from the zone of action of said knives will directly center said tube, and means to supply steam to the interior of said center tube.

4. An apparatus comprising a knife holder having a central passage through which a frozen pork sausage encased in cellulose casing is to be passed and a plurality of slots spaced equidistantly about said central passage, a knife pivotally mounted in each of said slots, said knives having their cutting edges disposed in spaced relation to each other in said passage to cut the casing of the sausage passing therebetween, means to maintain said knives under tension sufficient to cut the casing without substantially scoring the meat mass, means limiting movement of each knife about its pivot, a center guide tube, means attaching said knife holder to one end of said tube with their longitudinal center axes in alignment whereby a sausage passing from the zone of action of said knives will directly enter said tube, and means to supply steam to the interior of said center tube.

5. An apparatus comprising a knife holder having a central passage through which a frozen pork sausage encased in cellulose casing is to be passed and a plurality of slots spaced equidistantly about laid central passage, a knife pivotally mounted in each of said slots, said knives having their cutting edges disposed in spaced relation to each other in said passage to cut the casing of the sausage passing therebetween, means to maintain said knives under tension sufficient to cut the casing without substantially scoring the meat mass, a center guide tube, means attaching said knife holder to one end of said tube with their longitudinal center axes in alignment whereby a sausage passing from the zone of action of said knives will directly enter said tube, the wall of said guide tube having at least one circumferential row of slots spaced equidistantly in the center portion of the periphery thereof, a jacketed hollow cylinder in which at "least the portion of said guide tube having said slots is disposed in spaced relationship thereto, said cylinder having at least one circumferential row of orifices spaced equidistantly in its peripheral wall, and means in the jacket adapted to be connected to a steam supply.
