Adjustable packaging machine

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.
