A chuck for a meat encasing machine which has a meat emulsion pump in communication with an elongated stuffing horn, and a chuck housing on the machine adjacent the discharge end of the horn and having a rotatable chuck-receiving bearing means. A chuck member is imposed in the bearing means and includes a body member with a central hollow bore and a plurality of rollers rotatably mounted on the body member adjacent the discharge end of the bore. Each of the rollers has an axis of rotation which dwells in a plane substantially perpendicular to the axis of the bore. Each roller has outer meat encasing contact surface with the rollers being positioned on the body member so that the contact surfaces thereof collectively define a conduit for a meat-filled tubular casing passing through the bore in a direction from the intake end towards the discharge end. The contact surface of each roller is comprised of a plurality of disk portions having tapered peripheral edges which are adapted to deform a filled meat casing passing therethrough so as to impart rotational motion to the casing while at the same time imposing only a slight longitudinal drag thereon. |
