PATCH ·FOLDING

Patch Folding is hydraulically powered and elec– trically operated. Operating the pedal controls the electrical circuit whii:h energizes the solenoid of the Patch Folding. Circuit. This solenoid controls a manifold plunger which shifts the flow of oil to the Patch Folding Cylinder. When solenoid is de– energized, plunger movement causes oil to flow to

top of the Patch Folding Cylinder. This pushes piston down to lower· the Patch Guide and to close the Patch Folders. Energizing the Solenoid ·and the resu Iting valve movement, directs oil to the bottom of the Patch Folding Cylinder. This pushes the piston up to raise the Patch Guide and open the Patch Folders.

PATCH FOLDING METERING SCREW

PATCH FOLDING SPEED Speed of Patch Guide and Patch Folders is adiusted by varying the flow of hydraulic oil to the Patch Folding Cylinder by means of the Patch· Folding Metering Screw. TO ADJUST: Turning Patch Folding Metering Screw in (clockwise) slows movement. Turning this metering screw out (counterclockwise) pro– duces a faster patch folding action.
