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.
Claims5
An apparatus for binding smoking casings comprising:
- means for mounting a roll containing a web of casing material;
- means for forming a passage for said web of casing material;
- means disposed at a first position along said passage for perforating said web of casing material at predetermined intervals to provide lines of perforated holes;
- a plurality of rollers for creasing, folding and transporting said web of casing material, said plurality of rollers including first and second sets of rollers, each of said sets comprising plural parallel-mounted rollers and said first and second sets of rollers being disposed vertically with respect to one another;
- means for supplying a band of strap material;
- means for forming said strap material into a loop;
- means for disposing said loop of band material adjacent a creased end of said web of casing material;
- means for knotting said end of said web of casing material;
- and
- means for tearing said web of casing material along a perforated line of holes formed by said perforating means.
