ABSTRACT:
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.
