Title:
METHOD AND DEVICE FOR MANUFACTURING ROLL FILM FOR PHOTOGRAPHING
Document Type and Number:
Japanese Patent JP3652459
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a light shielding paper strip and a photographic film strip from being defectively wound in a spool and to prevent the photographic film strip from being damaged.
SOLUTION: A tension roller pair 39 giving a back tension to the light shielding paper strip 5 by a magnet brake 40 is arranged on the carrying path of the photographic film strip 4 and the strip 5 so as to prevent the strip 5 from meandering. A touch roller device 45 abutting on the shaft part of the spool 3 is arranged near a spool holder 43 to which the spool 3 is set so that the strip 11 and the strip 5 are tightly wound in the spool 3. Thus, when an opening seal is wound, the strip 4 is prevented from being damaged because it is contracted by the winding of the opening seal.
