Abstract

PURPOSE: To restrain the vibration of a wrapper roller by a method wherein a pressure increase, generated in a pressurizing side of a hydraulic cylinder providing a pushing force to the wrapper roller when a stepped portion of a strip is interferred with the wrapper roller, is maintained in a high degree.
CONSTITUTION: A pilot check valve 13, a chock valve 19, a relief valve 21 and an intermediate cylinder 11 are connected to a head side of a hydraulic cylinder 6 to oscillate a wrapper frame 3 having a wrapper roller 2 while the intermediate cylinder 11 is connected to an accumulator 12 and a pump 18 in series. A discharging side of the relief valve 21 is connected to a rod side circuit of the cylinder 6. The check valve 13 is connected to a 4-ways valve 15 through a parallel circuit comprising a reducing valve 14 and a check valve 20. When a stepped portion of a strip 5 is collided with the wrapper roller 2, a pressure in the head side of the cylinder 6 is increased, but an impact force upon the collision may be absorbed by a rightward displacement of a piston in the intermediate cylinder 11.
