ABSTRACT:
The invention comprises a novel apparatus having a plurality of flexible members which extend downstream horizontally along a wrapping conveying assembly for making unitary packages which are wrapped on all sides. The apparatus is particularly adapted for wrapping of loads with lengths and circumferences which vary substantially from one load to the next. Film is wrapped around the load, the flexible members and the conveying assembly with the load being carried off by another conveyor. The flexible members extend from the load being wrapped to the previous load which has been wrapped so that the stretched film is wrapped around the flexible member between loads causing the flexible members to be pulled inward forming a configuration resembling an hour glass. As the loads are being continuous bundled, the wrapped bundles can be transported downstream to a cutting and sealing area where the wrap is severed and optionally sealed forming individually enclosed wrapped packages.
