Abstract
A method and apparatus is provided for severing packaging material which extends between successive wrapped loads during a continuous packaging process. A conveyor assembly conveys the wrapped loads along a load path in a conveying direction. The conveyor assembly includes a first conveyor portion having a discharge area and a second conveyor portion having a receiving area downstream and a step down from the discharge area of the first conveyor portion. A severing assembly includes a severing element located above the second conveyor portion for severing the packaging material between loads. A pivoting breakaway mechanism permits the severing element to pivot in the conveying direction. An escapement mechanism, responsive to load sensors, transports the severing element to a position spaced from the load path when the severing element encounters a load.
