| titleOfInvention | Photo film roll diameter disc |
| abstract | (57) An object of the present invention is to provide a disk which can withstand many times of film feeding and can obtain a predetermined film pushing force. SOLUTION: Discs 19 and 20 are manufactured by forming a die in a disc shape by vacuum pressure forming on a sheet-shaped web 40 made of a resin material, and then punching the die into inner and outer diameters. The web 40 is made of a material capable of obtaining a measured value of 20000 times or more by a constant load fatigue test based on JIS K7118 in order to obtain durability. For example, PPE 62 parts, HIP S26 parts, styrene (S-EB-S) elastomer 1 One part is melted at 300 ° C in an extrusion film-forming machine and the thickness is 150 μ. Created with m. |
