The side squaring elements are disposed between the compression plates. The machine is controlled by a control system such that following a first strapping cycle and prior to a second strapping cycle the control system generates a signal to raise the compression plates from the load about 3 inches and a to move the side squaring elements away from the load about 3 inches.
