Abstract:
A web (14) of material such as photographic film is supplied continuously from a stock roll (16) into an infeed vacuum box (24) from which the web passes into an intermittently operated perforator apparatus (30) through which the web is drawn intermittently by a high performance vacuum drum (32) which feeds the web into an outfeed vacuum box (34) from which the web passes continuously to a rewind stock roll (44) or to other intermittently operated processing apparatus. Various patterns of widely spaced perforations and leader/trailer sections may be provided in the stationary web, which moves at high web speeds and accelerations between operations of the perforator apparatus.
