ABSTRACT:
Overlapped foil wrappers are formed by feeding a foil web (1 or 21) at uniform speed from an upper pair of rollers (2 or 22) to a lower pair of rollers (5,6 or 25,26) rotating at a uniform slower speed. A first cutter (3,4 or 23,24) between the upper and lower rollers cuts the web at intervals of the overall length of a wrapper, and such that an overlap is formed by the time the newly cut leading end of the web is engaged by the lower rollers. A second cutter below the lower rollers cuts the web downstream of the overlap to form the short wrapper piece (loose front foil). The lower roller (6) may move away from the other roller (5) while the overlap is forming, allowing the distance between upper and lower rollers to be reduced.
