5.2 Preventive maintenance The 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. 5.2.1 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). d Figure 17: Auto-grip shaft 3 A B If not, correct as follows: • Loosen the clamp (2) with the screw (1) till the cord is free on one side. • Shorten the cord by approximately 10 mm. • Put back the end of the cord underneath the clamp (2). • Secure it by tightening the screw (1) 2 1 5.3 Trouble shooting During processing wrinkles can show up in the image (1) on the in-feed table (2) and the process result (4) on the output table. The figures below show some examples where it is caused by the main rollers (3) or the pull rollers (5), and gives a possible solution. Wait until a few meters are processed to see results. Pressure too high. Figure 18: Wrinkles due to high pressure. • Decrease the nip pressure a little (5-10%). Pressure too low. Figure 19: Wrinkles due to low pressure. • Increase the nip pressure a little (5-10%). 30 Maintenance
Unwind tension too low. Figure 20: Wrinkles due to low unwind tension. • Increase the unwind tension until the wrinkles (6) in the film on the roller disappear. The lines (7) in the result will disappear as well. Roller alignment fault. Figure 21: Wrinkles due to faulty roller alignment. The wrinkles occur on one side only (left or right). • This is a machine adjustment error. Contact your dealer and ask for technical assistance. Material rolls are jumping. A regular tick can be heard in the shaft suspension. • Adjust the shaft support (1) by turning up or down the screw (2) with an Allenkey. Figure 22: Shaft support adjustment. 5.4 Technical assistance For technical assistance you can contact your dealer or the address on the copyright page in front of this manual.
