ABSTRACT:
An apparatus and method for continuously storing a strip of material in a coil, such as a multi-hour motion picture theatre film. The apparatus includes a flat platter with drive means for rotating the platter, a cam mounted for rotation with the platter and having a cam track with alternating sections of greater distance and lesser distance from the center of the platter, and means for applying the incoming strip to the periphery of the coil on the platter. The applying means includes a cam follower for engaging the cam track to position the strip in a coil on the platter having inwardly directed rounded cusps with arcuate outer peripheries therebetween. In order to reduce or eliminate tension in the strip, a roller is positioned at the outer periphery for urging the coil inward as the roller contacts the coil. Further improvements include provision of a high friction surface on the platter for enhancing arc formation and a low friction surface for enhancing cusp formation, and a takeoff roller assembly positioned above the platter for improved strip takeoff operation.
