FAQ - Cutters
  1. On short cut offs, the leading edge of the sheet follows the fly knife. My operator slows down the machine. What can be done to increase speed?


  2. During setup, the Operator sometimes has difficulty squaring the sheet. Any suggestions?


  3. When slitting coated paper, the sheets have dusty edges. What can be done to minimize this problem?


  4. I notice length variation when I sheet material. What can I do to prevent short sheets?


  5. We don’t have a squareness problem when sheeting a 50” wide roll. However, when we slit the same roll into 2 piles, 25” across, one sheet is square, while the other is not. What is causing the sheets to be out of square?


  6. How often should sheeter knives be changed?


  7. Is it necessary to replace both the top and bottom blades even though only one appears to be dull?


  8. During start-up, I get as many as 10 to 15 short sheets until the line speed steadies. Once I reach this point, my sheet length control is maintained. What is causing this variation?


  9. When taking a side trim, I sometimes find one side of the pile builds up higher than the other side. Why does this happen?


  10. When running two rolls of board superimposed on my dual knife rotary sheeter, the cut edge is clean, but the slit edge is dusty. What can be done to improve the quality of the slit edge?


  11. I have a problem with sheet length accuracy on my existing sheeter. On cutoffs less than 30” (762 mm) the sheet length is within tolerance, but it deteriorates on longer cutoffs. I also see more variation during start up and slow down of the line. Is there anything I can do to combat this problem?


  12. I have trouble maintaining edge trim at the slitters. How do I insure a steady ribbon of edge trim?


  13. I’m having trouble running 0.024” (400 gsm) thick board on my stationary bed knife cutter. The leading edge has a lip or "bead" on it and the trailing edge is fuzzy. What can I do to fix this problem?


  14. When I slit and run two piles, I have trouble with wrinkles on one side. How can I resolve this problem?


  15. When I slit and run two piles, one sheet is square and the other is out of square What adjustments can I make to address this?


  16. When I run two rolls of board on my machine, the sheets are not the same length. Why?


  17. I am running four rolls of paper, splitting it in half at the slitter section prior to cutting it. At the pile, the width of each pile varies noticeably. Why?


  18. I had been running my sheeter without any sheet squareness problems, but lately when I sheet 3 or 4 piles across the width of the sheeter, the sheets on the drive side are out of square. What can I do?


  19. The bottom rings on the slitter rig have a slight wobble, which causes a wavy edge on the side of the sheet. What can I do to fix this problem?
