Loose paper, in roll

1. Poor workmanship.
— the floor around and underneath winder must be kept clean to prevent static electricity from picking up pieces of paper.
2. Clean off dirty calender rolls that cause pull-outs that drop into reel.
3. Paper thrown from reel into a running winder where sheet is brought over after a break.
— the winder should not be left running when it is unattended.
4. Be sure enough paper has been torn-off winder before making a splice to preclude winder snap-off.
5. Do not use air hoses when winder is running.
— clean area between sets.
6. Using loose paper to build up a roll at start of a set is a practice that should be avoided.
7. If putting loose paper in butts, make sure paper does not go into adjoining roll.
8. May be caused by interruption of trimming system allowing some trim to get into windup roll.
— check air velocity in trim duct.
— make certain that trim is not too wide for system to handle.
9. Check and adjust trim guides.
10. If due to faulty slitters, they should be adjusted.
— if the slitters are defective, they should be replaced.
11. If due to insufficient web support, use additional bottom slitters to support web.
— on light weight papers, the trim should be supported as well.
