Abstract
A rotary perforator having a rotary anvil roll carrying one or two anvils cooperable with a fixed perforating blade edge for forming lines of perforations at spaced intervals along a continous web fed between the anvil roll and the blade edge, with provision for feeding the web and driving the anvil roll at different speeds, and for positioning the anvil roll at different skew angles relative to a plane transverse to the path of the web at right angles to the edges of the web so that the lines of perforations extend at right angles to the edges of the web, and with provision for forming the perforations in each line progressively across the web.
