  • Automatic chute opening system for strapping machine
    Patent number: 7263928
    Abstract: An automatic strap chute opening system for use in a strapping machine of the type having an openable, pivotable work surface for supporting a load to be strapped, and a strap chute defining a strap path through which the strapping material is passed. The chute is disposed in part below the surface and is openable to release the strapping material from the chute during the strapping operation. The chute opening system includes a torsional element operably connected to the strap chute for opening and closing the chute and an actuator operably connected to the torsional element. The coordinated movement of the actuator and torsional element corresponds with the opening or closing of the work surface.
