ABSTRACT:
The invention comprises a novel apparatus for making unitary completely wrapped packages. In the apparatus, a series of loads are fed into a wrapping apparatus onto a wrapping conveyor assembly comprised of a plurality of conveyors. The film is continuously wrapped around the load and the conveyor assembly to form a spiral bundle with the load being carried off by the top portion of one conveyor and the wrap being carried off the bottom portion of another conveyor so that the load and wrap are carried off at the same speed onto a take-off conveyor. The spiral stretched film web is sealed and severed between adjacent loads by a cutting and sealing apparatus to form a six sided compressive wrap around each load.
