Abstract
A strapping machine for positioning a strap material around an associated load, tensioning the strap material and sealing the strap material to itself around the load has an improved strap chute release system. Such a machine includes a frame, a strapping head mounted to the frame including at least a pair of wheels for feeding strap material and for retracting strap material and configured to seal a first course of strap material onto an overlying second course of strap material, and a strap chute mounted to the frame and configured for receiving the strap material from the strapping head and positioning the strap material around the load. The strap chute is configured to release the strap therefrom as the strap material is pulled to the load. The strap chute has an inner wall and a transverse wall defining a strap track from which the strap material is released. The inner wall is moveable away from the transverse wall for releasing the strap. The chute includes at least one torsion element operably connected to the inner wall to urge the inner wall from the transverse wall to a form a gap between the inner wall and the transverse wall.
