ABSTRACT:
A method and apparatus for producing smoking casings in which a web of tubular casing material is perforated in the widthwise direction at predetermined intervals. The web is then creased by roller discs and folded in a strip-like configuration. A doubly-folded band of plastic material having a notched portion is inserted between one of the creases and the assembly then clamped with a metal ring around the notched portion. Finally, the end of the web is clamped, then rotated in a direction tangent to the feeding direction of the web of casing material so as to tear completed casings from the web.
