HEIDELBERG GTO 52 / 52 Z / 52 V ADJUSTMENT OF PRESSURE BETWEEN BLANKET AND IMPRESSION CYLINDER

Adjustment of pressure between blanket and impression cylinder

is done by one each knurled knob (ill. 6/19). Settings are shown on graduated scales (ill. 37/3)

 Method of adjustment:

Deduct 0.1 mm (.004”) from the thickness of the stock to be printed and set both scales to this value (ill. 28/3). (0.1 mm = .004” is the pressure required.) (Observe: Measure paper thickness by means of micrometer or other suitable thickness gauge, the grammage of the paper does not indicated a true thickness.)

DOUBLE SHEET DETECTOR MESIN OFFSET OLIVER 52 - 8 - 58 - 12 - 66 - 72

DOUBLE-SHEET DETECTOR
Operating Procedure
(1) Turn the ON-OFF switch [1] ON. Then the indicator light [2] illuminates.
(2) Fully turn the adjusting knob clockwise and make sure that the needle of the meter [3] is at extreme right-hand side (blue zone).








(3) Insert a sheet of paper to be run between the light emitting and receiving elements as shown in the Fig. 2.
(4) Place the selector switch [5] in the METER position and turn the knob [4] counterclockwise (toward “0”) so that the needle of the meter [3] comes slightly to the right side (blue zone). Fig. 3.




(5) Insert another sheet of paper between the emitting ang receiving elements and check to see needle of the meter [3] moves to the left side (red zone) as shown in the Fig. 4.





*Note :
 PlacetheTHIN THICKselector switch [6] in the THIN or THICK position according to the thickness of paper to be used.

(6) Place the selector switch [5] in the CONT. Side ang push the CHECK push button [7]. Then the timing light [8] flicker at a time. If two sheets of paper are inserted between the light emitting and receiving elements, the ALARM light [9] illuminates at the same time.
When the selector switch [5] is in the CONT. Position and CHECK push button [7] is pushed, with two sheets of paper placed between the emitting and receiving elements, the timing light [8] flickers at a time and the ALARM light illuminates simultaneously.
This is how the machine stops when two sheets of paper are detected. If the CHECK push button [7] is pushed with a sheet of paper placed, are timing light [8] flickers and the ALARM light does not illuminate. The machine goes on working as it is.

*Note :
1.The machine does not work when the selector switch [5] is on the METER side.                                  2.Turn the ON-OFF switch [1] OFF when suffering losses in printing or binding.

ADJUSTMENTS OF INKING AND DAMPENING ROLLERS GTO 52

Are made in the normal manner by inserting two strips of paper, each 1/10 mm (.004”) thick and 5 cm (2”) wide, between any ruber roller and its adjacent steel roller end. The adjusting screws are always located at the operator’s and drive side of the press. The settengs must be identical on both sides.

a)      Ink vibrator roller No. 14 towards asclillating steel roller No. 13 : undo lock nut, adjust hexagon bolt (ill. 24/5), tighten lock nut after adjustment has been completed.

b)      Distributor roller No. 12 towards both adjacent steel rollers No. 13 and 11 : adjustment by means of thumb-screws (ill. 22/2)

c)       Distributor roller No. 10 towards both adjacent steel rollers No. 9 and 11 : adjustment by means of thumb screw as mentioned under b) with roller No. 12

d)      Form inking roller No. 1 : the adjusment of each form inking roller is combined in one adjusting mechanism at the operator’s and drive side of ther press. The countersunk screw marked by white paint adjust the form roller towards the plate, the second countersunk screw without a paint mark permits adjustment of the form inking roller towards its oscillating steel roller (ill. 22/5 shows the adjustment of form inking roller No. 1)

e)      Form inking roller No. 2 : adjusting mechanism on ill. 22/6. Both form inking rollers, i.e. No. 1 and 2, are adjusted from the feeder side of the press.

f)       Form inking roller No. 3 : adjusting mechanism on ill.24/7

g)      Form inking roller No. 4 : adjusting mechanism on ill. 24/8. Both form inking rollers, No. 3 and 4, are adjusted from the delivery side of the press.

h)      Dampening vibrator No. 20 againist steel oscillator No. 19 : adjustment by means of adjusting screw with lock nut (ill. 23/5). Here, the steel gauges delivered with the press are used instead of paper strips. Please see to it that the dampening vibrator roller touches the oscillating dampening roller with very light pressure only since you will otherwise encounter water transfer problems.

i)        Form dampening roller No. 17 againist steel rider No. 19 : adjust countersunk screw (ill. 23/6) by means of long screwdriver delivered with the press; adjustment towards the plate by the adjusting screw (ill. 23/7) but only while press is running. The setting is correct, if you notice a light roller bounce when the roller passes over the plate cylinder gap.

j)        Form dampening roller No. 16 towards plate : by means of knurled adjusting screw (ill. 23/8) the bouncing action is checked as with the upper dampening form roller.

k)      The removable dampening steel rider can be inserted, after tha supporting brackets (ill. 23/8) have been retracted by the lever (ill. 23/9) on operator’s and drive side. Once the levers (ill. 24/9) are swung back towards the dampening unit, the steel rider will be automatically adjusted by means of spring tension againist both plate dampening rollers. No other adjustment is necessary. If you want to disconnect the dampening form rollers on a particular printing unit off the plate, you can do so by means of the dampening roller locks (ill. 23/12) on operator’s and drive side of the press. Once the locks are in operation and the press is printing, the dampening form rollers in that particular dampening unit are not touching the plate.

Ink duct

After releasing both star handles (ill. 17/6) the ink duct can be swung away for easy cleaning. In order to prevent scoring between the ink fountain roller and the side plates of the ink duct the grease groove has to be filled with grease after cleaning the ink duct.

For accurat ink feed setting the ink duct is provided with 16 screws (ill. 24/9). A ratchet (ill. 24/11) on operator’s side and drive side allows to turn the duct by hand. The dampening fountain roller is equipped with one ratchet (ill. 23/11).
