Trims are jamming into Big8 trim guides / trims are flying anywhere

Possible solutions:

• Measure the cutting tolerances of at least one complete sheet:
  Is the diameter within tolerance ?
  Is the height within tolerance ?
  Is the angularity within tolerance ?

• Are there any burrs on diameter / height cut ? If yes, sharpen and reset the knifes first. Adjust the clearance between the knifes acc. manual.
• Are the width of both trims correct (min. 2mm) ?
• Measure the overlap of all Big8 knifes with the respective gauge:
  Target is 0.13 – 0.15 mm
• Make sure that the corners of the stripes are not damaged (before entering into the Big8 unit)
• Check the side centering system before 2nd operation: Is it correctly set ?
• Remove the trim guides, check them for any damages, and re-install them again:
  The gap between guide and top knife shall be around 0.2 mm.
• Make sure all transport rings are in good condition and correct positioned.
• Check the drive system of the Big8 unit:
  Is there any damage on the drive system and is the timing belt well tensioned ?
• Check the upper rubber / lower steel roller system after the Big8 (no direct impact):
  Is there any damage ? Is the gap between both rollers correctly set ?
