ABSTRACT:
A strapping machine and method for applying flexible, heat sealable straps around objects in which the supply coil of strap and the feed rollers for a strap accumulating compartment are driven by a common rotatable drive for synchronous feeding. A strap feeding unit for feeding flexible strap in which a feed and pinch roller extend through opposed slots which intersect a strap carrying groove which totally confines the strap.
A strap tensioning mechanism in which rough tensioning and final tensioning are achieved by the movement of a single mechanical plate. A cutting and sealing head in which feeding of a new strap around the object can occur simultaneously with the sealing of the previous strap. A track opening mechanism which is operated by components of the sealing and cutting head.
