Hot melt labelling
PROBLEM
Label stock entering into the label applicator can become highly charged on the lead and trail ends of the label.
This will result in:
- The label wrapping round the rotary knife
- Glue being applied to the vacuum drum
- Labels sticking to the vacuum drum and not the bottles
SOLUTION
Neutralising the web prior to entry to the applicator, will reduce the charges to prevent mis-feeding and subsequent line stoppages.
- The drawing shows (9) 924IPS bars mounted before the web guide.
- (10) a 261-flexi nozzle at the exit from the nip rollers prior to the cutting drum
