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 includes a strap chute having sequential strap release. The strapping machine includes a frame and the strap chute is mounted to the frame. The strap chute includes at least one fixed wall cooperating with at least one movable wall that, in a first position, defines a strap path through the strap chute and in a second position, releases the strap material from the strap path. A strapping head is also mounted to the frame. The strapping head is configured to convey the strap material into the chute and around the chute and to take-up and tension the strap material around the load. The strap chute includes at least one strap chute brush disposed between the at least one movable wall and the load. The strap chute brush has a length having a plurality of bristles transversely disposed along the length of the brush, the bristles extend proximal to the at least one fixed wall and define a gap between an end of the bristles and the fixed wall. The bristles and the gap are configured to sequentially release the strap material from the chute as the strap material is pulled onto the load.
