A strap joint rotating assembly is for use with a strapping machine. The strapping machine has a feed head for feeding the strapping material into the strapping machine, a strap chute through which the strapping material is passed and a sealing head to seal overlapping courses of the strapping material to one another to define a strap loop having a seal and defining a strap loop plane. The strap joint rotating assembly includes a driven wheel having an axis of rotation generally perpendicular to the strap loop plane and a pinch wheel that has an axis of rotation and is carried on a wheel block. The wheel block pivots to move the pinch wheel into and out of the strap loop plane. The pinch wheel, when in the strap loop plane, has its axis of rotation parallel to the axis of rotation of the driven wheel. The pinch wheel is further movable toward the driven wheel to pinch the strap between the driven wheel and the pinch wheel. The driven wheel is driven to rotate the strap loop around the load.

A strapping machine configured to feed a strapping material around a load, position, tension and seal the strapping material around the load, includes a work surface table height adjusting assembly. Such a strapping machine has a machine frame, a work surface for supporting a load mounted to the frame a strap chute for carrying the strap around the load, a feed assembly for feeding and retracting strap and a weld head for sealing the strap to itself. The machine frame is mounted to leg assemblies by first and second height adjustment assemblies. Each height adjustment assembly is configured to raise and lower a portion of the work surface relative to a fixed portion of the leg assemblies. The assemblies each include a pair of adjusting rods lying along a respective side of the frame, at adjacent corners of the work surface. The adjusting rods operably connect the work surface and the leg assemblies. Each adjusting rod is secured to its respective leg assembly by a support to restrain longitudinal movement of the rod and to provide rotational freedom relative to the leg assemblies and the frame. Each adjusting rod is engaged with an engaging member longitudinally movable along the adjusting rod that is mounted to the frame such that rotation of the adjusting rod raises or lowers the work surface relative to the leg assembly.

A strapping machine for positioning a strapping material around an associated load and sealing the strapping material to itself around the load, includes a modular strapping head and a modular feed assembly. The strapping head and feed assembly are readily installed on and removed from the strapping machine without tools. The Strapping machine includes a frame, a chute mounted to the frame and defining a strap path, the feed assembly mounted to the frame by a first aligning and mounting assembly, the strapping head assembly mounted to the frame by a second aligning and mounting assembly independent of the first mounting assembly, and a guide mounted to the frame adjacent the feed assembly. Both the feed assembly and the strapping head are independently removable from the frame.
