1.2 Sheet Separation and Suction Force
The holddowns (9-1) on the two sides of the sucker wheel
(9-2) should always be positioned slightly lower than the
sucker wheel. This causes the sheet which is sucked against
the wheel to arch up slightly allowing the top sheet to be
peeled away from a second sheet which may be clinging to it.
With stiff and heavy paper, the holddowns must be set so that
the suction wheel can still pick up the sheet.
The suction wheel is controlled by a solenoid valve (9-3).
The normal setting is indicated with a red mark.
The point at which the suction is applied can be adjusted
by swinging the suction point forward or backward with the
knob (9-4).
It may be necessary to move the suction point back if the
leading edge is curled down, or forward if the leading edge is
curled up. This adjustment can be further assisted by raising
or lowering the bridge with the knob.
The solenoid valve can be quickly and easily removed by
releasing the clamps (9-5) to allow dry cleaning of the inner
piston. To clean the piston cavity, unscrew and remove the
back cover (9-6) on the solenoid block and pull a soft cloth
through from the threaded side of the hole. Do not use any
solvent, lubricating agents or air blasts.
