<p>PURPOSE:To attempt simply and quickly positional adjustment of a press roller by energizing a plurality of the secondary side cylinders substantially at the same time and under the same pressure under an energizing action of the primary side cylinder and pressing uniformly a plurality of pressing members on the pressed body. CONSTITUTION:A cylinder rod of a cylinder is uniformly displaced by rotating action of a handle and then, a cylinder 30 is driven. Namely, a pressure oil introduced from a hole part 40 presses one face of a circular sheet 46, which displaces a cylinder rod 44 in the arrow mark direction against the elastic force of a coil spring 48. As the result, a blacket 56 is displaced and a roller 58 performs a positional displacement to a core material to change a pressing force. Namely, it becomes possible to displace a roller 58 fitted to a plurality of the secondary side cylinders 30 by a required distance in accordance with rotational action of the handle.</p> |
