    Abstract: A chuck for a stuffing machine for gripping and rotating a food-filled casing about a longitudinal axis to facilitate formation of links. The chuck has a plurality of antifriction free-wheeling rollers disposed along a longitudinal bore. Torgue for rotating the stuffed casing passing through the bore is transmitted by the engagement of a side edge of each roller against the casing. The casing, moving passed the rollers, causing the rollers to turn on their own axes so that torque transmission for rotating the casing about its longitudinal axis is accomplished with minimal longitudinal drag on the casing.
