Abstract
The present invention is an apparatus for applying high tension to strap in an automatic strapping machine. A rotatable frame has a first and a second position. Two driving wheels are mounted on the frame. In the first position of the rotatable frame, strap passes freely through a gap between the two driving wheels to allow feeding of the strap around an object and take-up of excess strap. In the second position of the rotatable frame the strap frictionally engages the periphery of the two driving wheels. Rotation of the two driving wheels when the rotatable frame is in the second position places high tension on the strap.
