ABSTRACT:
A palletized load is placed on a support that is straddled by a strap guide frame or yoke. The strap guide frame mounts strap feed and tensioning mechanism as well as an extendable-retractable lance that is extended and docked in the yoke to guide the strap between the decks of the pallet and back into the tensioning mechanism. Strap feed and lance extension are initiated simultaneously and the strap is fed around the guide frame toward the free end of the lance as the lance is being extended. The machine is shut off automatically by a timer relay if the lance has not docked before the leading end of the strap reaches the dock for the free end of the lance. The lance is extended and retracted by an electric motor drive to a friction drive mechanism. A timer shuts the lance drive motor off before the lance has been fully extended so that the lance coasts into its docked position.
