Cutting variations in stripes (blank development)

Possible cause:

  • wrong cutter setting
  • cutters are blunt
    • grind your cutters
  • watch the sucker unit in front of the 1. cutting operation for too much downwards bow of the sheet.
    • adjust bottom stop
    • replace worn out sucker or parts
    • mount the full range of downholder rings – see picture beside!
    • They prevent the bowing movement of the sheets.

NOTE:┬áThe SQM measuring device can only detect “angular” cutting errors!
