Abstract
A method and apparatus for winding film includes guiding a strip of the film through a winding machine to a rotating spindle. At least one deflector and/or at least one source of air, such as a nozzle, is moved to the path of the film downstream from the spindle, and an airhorn is moved to the spindle. The leading edge of the strip is directed into the airhorn by the deflector and/or air from the nozzle, and then directed by air within the airhorn into its own nip. Finally, the strip is wound about the spindle.
