  • Apparatus for electrically perforating moving paper webs
    Patent number: 4035611
    Abstract: Method and apparatus for electrically perforating a moving web such as paper, film and the like in which the web passes between spaced, charged and ground electrodes adapted to move at right angles to one another, including a flat plate for supporting said web as it passes between said spaced electrodes having a narrow slot in which the ground electrode travels parallel to the surface of said plate, said surface recessed along both sides of said slot to provide a collection area for particulate matter produced from perforating said web and means for removing said particulate matter from said collection area.
