ABSTRACT:
A versatile, space-efficient rotary sheeter including a pair of roll assemblies synchronously driven and rotating at web speed. Each assembly carries cooperating revolving cutter rolls and backup slot rolls staggered on opposed supporting roll assemblies and being readily shiftable, through gearing, between time-controlled operative and inoperative phasing modes for conveniently converting a moving web of roll stock of sheet material into cut segments of selectable lengths. The apparatus is physically fixed in place during operation and operates without any need for an accumulation loop in the moving web. The sheeter is readily adjustable, easily maintained, and has enhanced safety features. It operates over a wide range of adjustable speeds to accommodate web stock of various compositions and thickness.
