Abstract
A strapping machine feed system for automatically detecting a strap error or fault, thereby stopping strap retraction or take-up, and refeeding the strap into the strapping head following the error or fault. The feed system includes a pair of tensioning wheels disposed along a strap path proximal a strap supply, and a pair of feed wheels, defining a nip therebetween, disposed along the strap path proximal the strapping head. A feed wheel drive and a tensioning wheel drive are respectively connected to the feed wheels and the tensioning wheels. A sensor disposed along the strap path generates a signal to the feed wheel drive and tensioning wheel drive, indicating movement or lack of movement along the strap path, thus causing the feed wheels or tensioning wheels to rotate in both a forward and reverse direction.
