Patent ID: 6918228

Claim:
A method of applying a plurality of parallel reinforcing straps in predetermined spaced locations on a bulk box while the box is in a knocked-down or flattened condition, comprising the steps of: providing a machine having a plurality of spaced apart strapping head assemblies each operable to apply a reinforcing strap to the flattened box at a predetermined different location on the box; moving a box through the machine and past the strapping head assemblies; stopping the flattened box at each strapping head assembly to apply a strap to the flattened box in a position different from the position of a strap applied at a preceding strapping head assembly, but parallel thereto, and then advancing the box to a next strapping head assembly for application of a further strap, until the desired number of straps have been applied; operating each strapping head assembly while the flattened box is stopped to loop a strap around the flattened box, apply tension to the strapping, secure the strapping to itself to form a loop of strapping closely encircling the flattened box, and cut the loop from the supply, whereby a box erected from the flattened box has a plurality of spaced apart, parallel reinforcing straps pre-applied thereto.
