Abstract: A vehicle that includes a first rotatable frame that includes a first wheel assembly and a second wheel assembly. The vehicle also includes a second rotatable frame that includes a third wheel assembly and a fourth wheel assembly. The vehicle further includes a base frame configured to support a weight-bearing load. The vehicle further includes an axle member engaging the first rotatable frame, the second rotatable frame, and the base frame, wherein the first rotatable frame is rotatable about the axle member relative to the base frame and independent of the second rotatable frame, and the second rotatable frame is rotatable about the axle member relative to the base frame and independent of the first rotatable frame.

Abstract: An unwind station for a packaging machine may be configured to form wrappers having different sizes from a web of packaging material and supply the wrapper to a wrapping station. The unwind station may include a base configured to support the web of packaging material and a carriage configured to selectively slide in a longitudinal direction on the base. A rotating blade can be configured to periodically score the web to form a break line extending between lateral sides of the web. A first conveyor arm and a second conveyor arm may project longitudinally outward from the carriage. The first conveyor arm and the second conveyor arm can each include a low-speed conveyor configured to transport the web to a high-speed conveyor. The high-speed conveyor is configured to separate the wrapper from the web as the break line passes a shear point between the low-speed conveyors and the high-speed conveyors.
