Abstract
The invention comprises a novel apparatus and process for making unitary packages. In the apparatus, a series of loads are fed into a wrapping apparatus onto a wrapping conveying assembly comprised of a plurality of conveyors. The film is wrapped around the load and the conveyor assembly 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 stretched film web can be severed by a cutting mechanism positioned adjacent the dispensing means in the banding, full web or spiral modes of operation. In a continuous bundling mode, the wrapped bundle can be transported downstream to a cutting area where the loads are severed into individual packages which are carried off to a stacking or processing station.
