Abstract
The invention comprises a novel apparatus and process for making unitary packages from a continuous wrapping process. In the apparatus a series of loads, each containing a plurality of cartons are fed into a wrapper apparatus and covered by a spiral stretched film to form a unitary continuous packaged bundle. The bundle proceeds on to a cutting area where the loads are severed into individual packages which are carried off to a stacking or processing station. The apparatus utilizes wrapping guide rails which receive the loads so that the wrapping ring mechanism continuously wraps each load and its supporting guide rails with the wrapping being pulled off the guide rails to contact against each load forming a spiral wrapped bundle encapsulating the loads. The spiral bundle is carried to a cutting station which severs each individual load from the spiral bundle.
