The Upper Roll
• Switches off the compressed air inside the machine. (LTL>0 comsup)
Check if the roll is not dirty or damaged.
• Align the upper roll assembly mechanically until the roll becomes parallel to the
drum.
• Change this position by loosing the screws which are fixing the roller assembly on
the drum bearing blocks.
• Take care that you do not hit the drum surface with the unload table.
• Be sure to tighten the 4 screws very well.
Adjustment of the duplex cylinder (B440718)
The yellow roller has two positions. One position is just above the film(loading)
controlled by longest cylinder(2 sfdrel) and the second position is against the
film(unloading) controlled by both cylinders(2 sfdrel 8 siorel)
• Turn both shafts of both cylinders completely in.
• We will first adjust the roller to the rollerloading position.(2 sfdrel)
• Adjust the speed and the depth of the roller. In the front of the subrack there are
several speed controllers. The first speed controller (=top) controls the speed of
the roll coming down. The last speed controller (=bottom) controls the speed of
the roll coming up. First close them both. Switch the compressed air on with the
command “LTL>1 comsup”.
• The command to let the upper roll down is “2 SFDREL” and for going up “2
RFDREL”.
• Perform those commands several times and at the same time open the speed
controls little by little until the desired speed is accomplished.
• Adjust the end position of the roll when it is down.
• Turn the shaft of the cylinder until the desired distance is reached. The perfect
distance between the roller and a film is when the roller is softly touching the film.
Be sure to seal the shaft of the cylinder with the nut.
• Check the distance always with compressed air on and performing the commands
“2 SFDREL” and “2 RFDREL”.
• We will now adjust the roller to the rollerunload position.(2 sfdrel 8 siorel)
