Abstract

A film winding apparatus has a film winding mechanism for rotating a roll core to wind an elongate film around the roll core thereby to produce a film roll, a product receiving mechanism for gripping the film roll while tensioning the elongate film, the product receiving mechanism being displaceable away from the film winding mechanism, and a cutting mechanism for transversely cutting off the elongate film while the elongate film is being tensioned by the product receiving mechanism. The elongate film can be wound highly accurately around the roll core with a simple process and arrangement.
