ABSTRACT OF THE DISCLOSURE An apparatus for wrapping a plurality of successive loads into wrapped packages comprising a conveyor adapted to receive the loads and a film dispensing apparatus including a ring member rotatably mounted on a frame, a film roll support and brake member mounted on the ring member. A guide wrapping rail is aligned with the conveyor to receive and carry the loads transported by the conveyor and is so positioned that one end passes through the ring member. A material handling assembly having two clamp mechanisms is positioned adjacent the dispenser apparatus. One of the clamp mechanisms is adapted to alternately hold the leading edge of a roll of stretchable material, carried by the ring member film roll support, in a fixed position while the other clamp mechanism holds the trailing edge of the stretchable material to form the package wrap. Each clamp mechanism comprises two opposing bar members and a cutting blade secured to one bar member with its cutting edge being positioned between the two bar members for severing the web of the last wrap of overwrap material placed around the load. A drive wheel engages the ring member to alternately rotate the ring member in alternate opposite directions so that it dispenses material around the guide rail, the clamp mechanisms, and the load cur- rently being carried by the guide rail with the brake member stretching the material as it is being placed around the load. A method of wrapping is also disclosed.
