Abstract: Method of and apparatus for intermittently dispensing of filled products, in which is provided an automatic continuous control of expansion of the casing during the filling of the item and closing its ends by variable degree of a pressure of a fluid mass in a swelling member.

Abstract: A stuffing machine has device for holding and stuffing a tubular casing of a food product with a filling material, and a supporting device for supporting stuffed downstream portion of the tubular casing with relative rotation of the devices to twist the tubular casing therebetween. The supporting device includes a swelling member with an inner space which can be filled with air to swell the member with resulting gentle embracing and supporting the stuffed portion by the member and be emptied of air for terminating the supporting and releasing the stuffed portion.
