ABSTRACT:
This relates to the formation of packages of containers, particularly those formed by heat shrinking a plastics material wrap around a plurality of containers and wherein the package is intended to be picked up by engaging an upper central portion of the wrap. A reinforcing strip is interlocked with upper portions of central ones of the containers. The reinforcing strip is divided in roll form and is first perforated to interlock with upper portions of containers, then is applied to adjacent pairs of containers followed by pressing the reinforcing strip down to assure interlocking thereof with two adjacent containers of two adjacent pairs of containers with the strip being severed between the two adjacent containers while held in place relative thereto. The containers are continuously moving during the application of the reinforcing strip and a single movable support is provided for all of the apparatus components. The movable support is driven by a plurality of cooperating cranks.
