PURPOSE:To enable fine adjustment of a gap between a presser drum and a rubber drum simply and speedily by rotating eccentrically a housing for the bearing of the presser drum by means of a screw axis and the 1st and 2nd link motions. CONSTITUTION:When a gap N between a presser drum 1 and a rubber drum 2 is set through fine adjustment so as for it to correspond to the thickness of a printed metallic plate, a lock pin 9a is released by a nut 9 and a knob 6 is operated through rotation, thereby fine feeding for advance or retreat being applied to a screw axis 8. By this, the link motion is given to the 1st link mechanism, as well as the 2nd link mechanism through a relay axis 13, and an operation rod 20 rotates finely a housing 27 for the bearing in accordance with the feeding quantity for advance or retreat of the screw axis to displace the position of the axis of the presser drum 1 and adjust finely the gap N, while the rotation of the knob 6 being restricted through the lock operation of the lock pin 9a by means of the nut 9, thus the adjusted position being set. |
