Abstract:
1. An asymmetrical chute system for a strapping machine of the type for feeding a strapping material around a load, positioning, tensioning and sealing the strapping material around the load, the strapping machine having a feed head for feeding the strapping material into strapping machine, a strap chute defining a strap path through which the strapping material is passed and a sealing head to seal overlapping courses of the strapping material onto itself, the asymmetrical chute system comprising a base; a stationary guard, the stationary guard having an inclined wall extending, at least in part, over the strap path; and a movable guard, wherein the stationary guard is stationary relative to the base and the movable guard, and wherein the movable guard is movable relative to the base and the stationary guard, the movable guard being movable into engagement with the stationary guard inclined wall to open and close the strap path, wherein when the movable guard is open, the inclined wall extends over the strap path so as to form a blind portion intersecting a line normal to the strap path wherein the stationary guard includes a reverse bend extending from the inclined wall and back over the line normal to the strap path, and the stationary guard further includes a portion extending from the reverse bend defining a stationary guard exit wall configured as an exit path for the strapping material to move toward the load, the stationary guard exit wall is positioned substantially parallel to the line normal to the strap path.
