Abstract
An article and method for use in making stuffed food products with at least one flat end has a plurality of annular discs connected one to another by a long tubular membrane which passes through the central opening in each disc. The membrane is transversely circumferentially perforated between each disc and stuffing pressures cause the tubular membrane to longitudinally extend and tear at the preforations so that discs can be longitudinally separated and introduced one at a time into the stuffed food product for flattening an end of the product.
