ABSTRACT:
A perforator for perforating a web. The perforator has a rotatable drum for supporting the web; an arm having a punch, which rotates integrally with the drum; a driver for swinging the arm, which rotates integrally with the drum; and a taper rib which does not rotate with the drum, in which the taper rib is provided with a roller gear cam for engaging with the taper rib which is provided on a circumference concentric with the drum in a cross section perpendicular to an axis of the drum, so that the taper rib causes the driver to swing and the punch perforates the web with rotation of the drum.
