ABSTRACT:
A machine and method for applying reinforcing strapping to bulk boxes. The machine includes a plurality of strapping head assemblies arranged in series, with each adapted to apply a strap in encircling relationship to a box at a predetermined location on the box. As the box advances through successive strapping head assemblies, straps are applied in predetermined spaced relationship on the box, until the desired number of straps have been applied. The number, spacing and tension of the straps may be quickly and easily adjusted. In an embodiment of the invention, the strapping head assemblies are arranged in pairs in individual modules. A recovery strapping head assembly is provided just prior to exit from the machine to apply any strapping missed by a preceding strapping head assembly.
