ABSTRACT:
A method and apparatus for assembling and dispensing a multi-ply web and wrapping a load with the multi-ply web includes a film web dispenser for receiving a plurality of webs from a plurality of rolls of web material, juxtaposing the plurality of webs to form a multi-ply web and dispensing the multi-ply web. The load is rotated relative to the film web dispenser to wrap the multi-ply film on the load and tension is maintained on the multi-ply web between the film web dispenser and the load. A core material such as a web of foam, UV-resistant material, or reinforcement netting is inserted between the plurality of webs prior to dispensing the multi-ply web. Rollers and a clutch and brake assembly are used to intermittently forward the web of core material.
