6.2 Preventive maintenance
Our machines are designed in such way that they need little (preventive) maintenance in addition
to the cleaning.
The following checks have to be performed:
• Auto-grip shafts with blocking cords.
6.2.1 Auto-grip shafts
Check the auto-grip mechanism on each shaft.
• The distance (d) between the rubber cords and the edges of the recess should be 8 ± 2.5 mm
minimum (the cord must not touch the skew).
Figure 18: Auto-grip shaft
If not, correct as follows:
• Loosen the clamp (2) with the screw (1) until the cord is free on one side,
• Shorten the cord by approximately 10 mm (0.4 in.),
• Put the end of the cord back underneath the clamp (2),
• Secure it by tightening the screw (1).
6.3 Trouble shooting
During processing wrinkles can show up in the image (1) on the in-feed table (2) and in the
process result (4) on the output table.
The figures below show some examples where it is caused by the main rollers (3) and gives a
possible solution.
Wait until a few meters is processed to see results.
Pressure too high.
Figure 19: Wrinkles due to high pressure.
• Decrease the roller pressure a little (5-10%).
