Abstract
Abstract Deckle grinding apparatus is described wherein a web of material, such as paper, is wrapped approximately 180* around a support drum so one or both edges overhang the drum. Tension is applied to the web to provide increased strength to permit a grinding wheel at an angle to the longitudinal axis of the drum to grind a deckle on the edge of the web.
