Abstract

A strapping machine for positioning a strapping material around an associated load and sealing the strapping material to itself around the load includes a frame, a chute mounted to the frame, a feed assembly mounted to the frame a guide mounted to the frame adjacent the feed assembly and a strapping head mounted to the frame independent of the feed assembly and the guide. The feed assembly is configured to feed the strapping material therethrough. The guide receives the strapping material from the feed assembly and provides a path for the strapping material toward the strapping head. The strapping head includes a body and provides a first conveyance path for the strapping material from the guide to the chute. The head includes a second conveyance path to receive a free end of the strapping material to seal the strapping material to itself. The strapping head has an anvil pivotally mounted to the body that forms a part of the second conveyance path. The anvil pivots between a first conveying position in which the anvil is pivoted away from the body to enlarge the second conveyance path and a second sealing position in which the anvil is pivoted toward the body to narrow the second conveyance path.
