A strapping machine configured to feed a strapping material around a load, position, tension and seal the strapping material around the load, includes a chute opening system to open a lower portion of the strap chute upon upwardly pivoting a portion of the work surface. Such a machine includes a machine frame, a work surface for supporting the load in the strapping machine, at least a portion of which is upwardly pivotal. A strap chute carries the strapping material around the lo ad and releases the strapping material from the strap chute. The strap chute define s a strap path along the chute. The chute is movable between an operating position in which the strapping material is conveyed along the chute and a release position in which the strap chute is moved longitudinally to release the strapping material from t he chute for positioning around the load. A weld head seals the strapping material on to itself. At least a portion of the weld head is disposed along the strap path below t he work surface. The chute opening system is operably connected to the chute and is engageable with the upwardly pivotal portion of the work surface. The chute opening system includes a contact arm for engaging a lower surface of the work surface. The contact arm is operably connected to the chute such that upward pivoting of the work surface moves the chute from the operating position to the release position.
