Abstract: A method and apparatus for providing corners of a load with cornerboards prior to wrapping the load is provided. The method may include providing a load on a load transport surface, removing a cornerboard from within a magazine by a gripper, and transporting the cornerboard to a corner of the load with the gripper. Relative rotation may be provided between the stretch wrap packaging material dispenser and the load to wrap the stretch wrap packaging material around the cornerboard and the load. If the cornerboard is not pre-formed, it is folded prior to transport to the load. The cornerboard is secured to the corner of the load with the stretch wrap packaging material. In a preferred embodiment, four magazines and four grippers are provided, such that four cornerboards can be carried to the load at the same time.

Abstract: A method and apparatus for wrapping the load at a desired wrap force are provided. The apparatus includes a dispenser for dispensing packaging material and means for providing relative rotation between the load and the dispenser. The dispenser has a prestretch portion and a post-stretch portion. The prestretch portion is configured to prestretch the packaging material within the dispenser to a point below the yield point of the packaging material. Preferably the packaging material is prestretched between first and second unpowered prestretch rollers. The post-stretch portion is configured to further stretch the prestretched packaging material to a point above the yield point of the packaging material as the packaging material moves from the dispenser to the load. Preferably, the post-stretch portion includes a friction element, such as a brake, to apply friction to one of the prestretch rollers.
