Abstract: A sheeting apparatus and method are disclosed for cutting a web of material passing through a printing press into sheets. The apparatus comprises a rotating die roller including a knife mounted longitudinally thereon, the die roller being connected to the printing press transversely to the web and moveable between an engaging position wherein the knife rotates into cutting engagement with the web and a released position wherein the knife does not contact the web. A pair of springs bias the die roller into one of the engaging and released positions and a pair of linear actuators are provided to selectively move the die roller into the other of the engaging and released positions in opposition to the spring bias. The sheeting apparatus further includes a programmable controller for automatically operating the actuators. The method involves cyclically moving the die roller between the released position and the engaging position at intervals to cut the web into sheets of a predetermined length.
