PURPOSE:To improve operation efficiency by a method in which the first and second supporting parts of a feeding roller and a winding roller, and the guiding parts sliding the rollers from the second supporting part to the first supporting part, are provided, whereby the heavy roller is once placed on the second supporting part on which the roller is easily placed, and then the roller can be mounted on the first supporting part, while sliding the guide parts. CONSTITUTION:Are shape recesses 18B, 19B, as temporary mounts, are provided at the operation sides of supporting parts 18, 19. Guide rails 18C, 19C are provided on the supporting parts 18, 19 between said arc shape recesses 18B, 19B and the arc shape recesses 18A, 19A becoming the mounting parts for a feeding roller 2 and a winding roller 4, whereby the heavy rollers 2, 4 are mounted in the arc shape recesses 18B, 19B, and then the rollers 2, 4 can be simply mounted in the arc shape recesses 18A, 19A by only rolling the guide rails 18C, 19C. Therefore, the efficiency of the mounting operation of the rollers 2, 4 can be improved. Because the operation in which operators support the heavy rollers 2, 4 and fit them to the device is not required, the drop, etc., of the rollers 2, 4 do not occur and the safety in the mounting operation can be enhanced. |
