Abstract
A strapping machine for positioning a strap material around an associated load and tensioning the strap material around the load includes a frame for supporting the load, a chute positioned on the frame for receiving the strap material and orienting the strap material around the load, a strap supply and a strapping head for extracting the strap from the supply, feeding the strap through the chute around the load, passing the strap from the chute around the load, retracting and tensioning the strap. The strapping head includes feed rollers and retraction rollers for feeding and retracting the strap and a winder for tensioning the strap around the load. The winder is positioned between the feed and retraction rollers and the strap supply. The winder includes a rotating head portion having a stationary element and a pivotal element. The stationary and pivotal elements each define an outer surface around which the strap material is wound and a slot therebetween for receiving the strap material. The stationary and pivotal elements each further define a gripping portion at about respective ends opposingly facing one another. The pivotal element is pivotal between an open position in whic…
