Adjusting the intermediateroller in relation to thedampening form roller

Engage dampening form roller to the plate (notin the cylinder gap). No separation between theintermediate roller and the first inking formroller).

Use the adjusting screws (fig. 28/1) to adjustthe intermediate roller in relation to the damp-ening form roller. It must be possible to with-draw the strips of paper on DS and OS(fig. 28/2) with the same force of pull.

After you have taken out the strips of paper,turn the adjusting screws half a revolutionclockwise.

- Use a fork wrench to lock the adjusting screwsin position (fig. 29/1).

The contact pressure against the inking formroller is produced by spring force, and has beenadjusted in the factory.

Checking the adjustment with roller marks

- To check the adjustment of the dampeningform roller in relation to the distributor roller,and of the intermediate roller in relation to thedampening form roller with roller nip marks,allow light-coloured ink (e.g. yellow) to flow intothe inking unit until the dampening unit hasbeen inked.

- Stop the press and inch it until the contactstripes are visible:

If the adjustment̂ etween the dampening formroller and the distributor cylinder and between thepiate dampening roller and the intermediate roller

1E8

is correct, you will see a roller mark of 4 to 5 mm(0.157 to 0.197").

- Wash up the inking unit and dampening sys-tem.

Installing the metering roller

Before installing the metering roller, make surethe adjustment is the same on both DS andOS. To do this adjust the 3rd tooth of the gearsegment (fig. 31/3) to the front edge of theworm gear housing (fig. 31/2) with the adjust-ing worm gear.

- Mesh the metering roller on the DS with thegear wheel (fig. 30/1), and place it on the OSbearing (fig. 31/1).

- Push D towards the DS as far as it will go.

- Use a hexagonal spanner (fig. 31/4) to screwthe OS roller journal to the bearing.
