Abstract

Tipping papers are cut from a continuous strip of material advancing along a set feed path by a unit comprising a suction roller and a roller equipped with blades, which combine to separate the single papers from the strip at a prescribed frequency; the tension of the advancing strip is varied cyclically by diverter elements associated with the suction roller and capable of movement at intervals coinciding with the frequency of the cutting stroke between two limit positions, one located externally and the other internally of the outer surface presented by the suction roller.
