ABSTRACT:
A film magazine forming apparatus forms a sheet having printing on a side thereof into an almost cylindrical shape. The film magazine formed into the almost cylindrical shape has separated lip portions for enabling a film to mvoe therethrough. The lip portions have a soft yarn mounted thereon. Transport apparatus transports the sheet to forming means including a core mold, an upper mold, and first and second side molds which form the sheet into an almost cylindrical shape with the printing on the side of the sheet forming an outer cylindrical surface of the almost cylindrical sheet. Transport apparatus transports the sheet with the printed side of the sheet being out of contact with the transport apparatus to prevent damage to the printing on the sheet. In addition, the core mold is used as a guide for transporting the almost cylindrical shape sheet to another operating position. A claw can be mounted on the core mold for transporting the thus formed almost cylindrical shape to another operational position.
