ABSTRACT:
A strapping machine feeds strapping material around a load, positions, tensions and seals the material around the load. The machine includes a work surface, a portion of which is upwardly pivotal. A conveyor mounted within the work surface has a friction belt drive. The conveyor roller closest to the strap chute has a middle portion that has a smaller diameter than the end portions. The middle portions are fitted together to rotate as a unitary element. A load compression assembly is mounted at the strap chute. A side squaring assembly aligns the load in the direction transverse to the load direction. A strap guide extends between a pre-feed assembly and the feed assembly and includes a fixed portion and a movable portion forming a guide path that is opened to access the guide path. An interlocked enclosure is mounted to the machine frame below the work surface to access the sealing head and the feed assembly.
