  • Patent number: 4708044
    Abstract: A device for cutting animal intestines into predetemined length for use as sausage casings comprises a pair of upstanding L-shaped mounting plates between which a circular shaped knife is secured. The top edge of the mounting plates is formed with a groove through which the knife cutting edge extends. In use, intestinal tissue is squarely cut by throwing a length thereof onto a central top edge of the mounting plates for movement in the direction of the groove. The intestine enters the groove and descends to a point where the cutting edge intersects one of the groove walls at an acute angle where cutting occurs. This groove wall is bevelled with respect to the knife to slice the casing material quickly in a square cut. Fresh cutting edges may be exposed in the groove by rotating the knife when necessary.
