Abstract
A pneumatic clamp is disclosed for use in thermomagnetic duplication systems. The clamp comprises a nip member having a web-guiding surface with at least one passageway, means for connecting that passageway to a source of pressurized gas, and means for urging the nip member toward a roller whereby the pressurized gas exiting the passageway(s) will (a) cause a web or webs disposed between that surface and a roller to be pressed against the roller, (b) exert a back pressure urging the web-guiding surface away from the roller, and (c) form an air bearing between the nip member and the web or webs.
