An apparatus and process for wrapping loads into wrapped packages employ a pusher conveyor for feeding the loads to a film dispensing apparatus comprising a frame, a ring member rotatably mounted on the frame and a brake member mounted on the ring member. A load support rail is aligned with the conveyor to receive the loads. A film material handling assembly adjacent the dispenser apparatus has two clamps, one of which alternately holds the leading edge of stretchable film material carried by the ring member in a fixed position while the other holds the trailing edge of the stretchable film material forming a package wrap. The material handling assembly also includes a cutting bar positioned between the two clamps for severing the web of the last wrap of the material around the load. A drive wheel engages the ring member to alternately rotate the ring member in alternate opposite directions so that it dispenses the material around the guide rail, the material handling assembly, and the load currently being carried by the guide rail, with the brake member stretching the material as it is being placed around the load. |
