PURPOSE:To reduce the number of motors driving a feeding reel, a take-up reel, a sprocket, a recovery reel by slipping a friction rotary transfer part with gradual enlargement of a reel diameter of the take-up reel with working progress by reducing the number of revolutions to be transferred to the take-up reel. CONSTITUTION:A first motor M1 rotates initially at a low speed so as to quantitatively let out a film carrier 3 and a separator 4 and with a decrease in a reel diameter of a feeding reel 22, the number of revolutions increases. The feed speed of the film carrier 3 and the taking-out speed of the separator 4 can be equalized inspite of a size change of a reel diameter of the film carrier 3 of the feeding reel 22 and of a reel diameter of the separater 4 of a take-up reel 25 with progress of operation. Further, due to such constitution of a first transfer system, a difference in rotational speed is absorbed so that the feeding reel and the take-up reel are driven by the common and same first motor M so as to reduce the number of motors. |
