ABSTRACT:
Apparatus for producing discrete blanks from a web of foil or the like is provided, in which the foil or the like are given continuous constrained guidance during the phase between separation of the web until transfer to a packet or packing machine. The web is transported into the system between a first pair of pulling rollers then transferred to a conveyor of two spaced belts. The belts are provided with a series of apertures through which a suction is pulled to hold the transported web. The belts diverge slightly and pull the web at a higher speed than the first pair of rollers so that the web is stretched both lengthwise and transversely. Severance from the web is carried out in at least one initial cut, followed by a main cut, during continuous constrained guidance.
