ABSTRACT:
A spooling apparatus attachable to a printing press and operating under pneumatic control and power. An elongated web passes through a linear slitter, over a unidirectional roller, and onto a take-up spool. The spool rotates on power received through a belt drive and a variable speed gear box from the press itself. Upon the receipt of a signal from the press, a pneumatically controlled and powered knife cuts the web and urges it onto another spool. A spring dampener keeps the knife from bouncing and produces a clean cut. When the knife returns to its original position, the pneumatics applies a brake to the full spool to stop its rotating and allow the operator to remove the spooled web. The pneumatics then lifts a cam follower from a stop in a cam and engages a clutch to rotate the frame which holds the rollers for the spooling. This brings the filling spool to the location previously occupied by the full spool. There it continues to rotate and take up the web. Magnetic clutches on the rollers allow for the application of a constant force to them notwithstanding the constantly increasing circumference on the spool receiving the incoming web.
