Abstract
An apparatus for controlling the size of a casing filled with emulsion in an automatic stuffing machine includes a drag member between an outer surface of the stuffing horn and an inner surface of the casing sleeved over the stuffing horn. The drag member has a drag surface. A pressurized fluid system expands the drag member so that the drag surface contacts and exerts a force against the inner surface of the casing in opposition to movement of the casing on the stuffing horn as it is being filled and expanding radially outwardly. A control circuit controls the expansion of the drag member to vary the force applied by the drag surface against the casing inner surface to control the radial expansion of the casing as it is being filled with emulsion. The control circuit may include a feedback system from the portion of the casing expanding radially outward to control the expansion of the drag member in response to casing size.
