Abstract
An encased product is formed by continuously applying an elongated flexible ribbon to the outer cylindrical surface of a stuffing tube at a canted angle with respect to the longitudinal axis of the tube and rotating the flexible ribbon at the point where it is applied to the stuffing tube so that it will wrap around the tube in a plurality of helical revolutions to form a cylindrical casing on the tube. The adjacent edges of the helical revolutions of the ribbon are frictionally overlapped to one another so as to form a cylindrical casing and product is forced through the tube from the rearward end to the discharge end and into the cylindrical casing. The stuffing tube may be a rotating stuffing tube or it may be a stationary stuffing tube. A ribbon feed device is provided for feeding a continuous strip of ribbon to the stuffing tube.
