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.

Pneumatically controlled spooling apparatus

To provide a reinforced paper sheet which has curl-resistant edges so that it will not jam high-speed copier machines, the edges of the paper sheets are reinforced with very thin Mylar strips which are symmetrically mounted on both sides of the edge of the sheet of paper. The strips are preferably about one-half inch wide and may be mounted slightly back from the edge of the sheet of paper. In the manufacturing step, it is desirable that the two strips be applied precisely symmetrically, and preferably simultaneously, so that any stresses are equal and opposite on the two sides of the paper so that the paper resist curling. The Mylar strips may be very thin, such as one-half of a thousandth of an inch in thickness, and the adhesive may be a hot melt type of adhesive which is strictly confined to one side of the Mylar reinforcing strips.
