ABSTRACT:
A method and apparatus for unitizing a load of tires stacked in a longitudinal direction. The stack of tires is compressed in the longitudinal direction between two platens located adjacent the ends of the stack of tires. A web is dispensed and stretched along the direction in which it is dispensed. A leading end portion of the web is held adjacent the stack of tires and mandrels are positioned adjacent the ends of the stack of tires. The stack of tires is rotated relative to the web dispenser about its longitudinal axis. The stretched web is wrapped around and onto the compressed stack of tires and the mandrels, forming a tube which extends in the longitudinal direction beyond the stack of tires and on the mandrels. The mandrels are separated from the web and the stack of tires and the web is collapsed from the mandrel onto the stack of tires, covering the sidewalls of the tires at the ends of the stack.
