A stretch wrap packaging machine includes a support frame and a rotatable frame rotatably mounted on the support frame. A dispenser is mounted on the rotatable frame to follow an orbital path. The dispenser has a web tensioning system which is selectably operable in a plurality of states. At least one actuation ring is moveably mounted on the support frame for cooperation with the tensioning system and selectively rendering the tensioning system operable in each of the plurality of states of operation throughout the orbital path. An activator moves the actuation ring to cooperate with the tensioning system. The tensioning system may include prestretch rollers connected by an engageable clutch. The tensioning system may also include at least one power assisted roller which is connected by a clutch to a power source.

Stretch wrapping with tension control

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.
