Fluid under constant pressure is delivered through rotary directional valve 7 to operating cylinder 1, and ram 2 together with shear head 3 and blade 4 descends, shearing billet 9. At this, fluid from cylinders 5 is discharged to tank 6. For the return stroke of blade 4, valve 7 is turned. Then fluid is delivered to cylinders 5. This moves plungers 8 with shear head 3 and blade 4 upward. Fluid is discharged from cylinder 1 to tank 6.
