ABSTRACT:
Support and tensioning apparatus for a strapping band to be tensioned around a package. A band first pressed between a pair of wheels and advanced in a band guide that surrounds but does not contact the package. The band is subsequently retracted with its front end secured in place into a position against the package by reversing the sense in which the pair of wheels rotates, and is then tensioned with a separate tensioning wheel that rotates slowly and at high power. The strapping band is tensioned with a pair of wheels of which one wheel is an idler wheel and the other wheel is a tensioning wheel powered in the tensioning direction by a motor and with its shaft mounted in a pivoting lever in such a way that the wheel presses against the strapping band, which is to some extent looped around it, while the band is being tensioned and rests on the idler wheel, with a force that increases with the tension in the band.
