Abstract:
A method and apparatus for making and winding bags is disclosed. The film approaches the infeed nip on the surface of a roller and on a film guide recessed in the roller for an arc of at least 10, 45, 60 or 90 degrees. The film is preferably guided to one of two alternative film paths. An over speed nip may be provided between the infeed nip and the alternative film paths to separate rolls or to separate all bags. An overlapper can be included. Rods that travel in an elliptical orbit, and/or air nozzles can be part of the overlapper. Air nozzles or a rotating brush can direct the film to the appropriate alternative path. Banders can be used, and can include a conveyor for providing tape to the spindle and two sources of air.
