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

Answer: Short sheet lengths are usually associated with excessive brake pressure at the roll stand or inadequate nip roll pressure. See if less brake and heavier nip at the cutter's squeeze roll remedies the problem.

The surface of draw drum and squeeze roll should also be checked. If either roll is glazed or slippery, the web may not be pulled in uniformly, which can lead to short sheets.

To remove the glaze on the rubber covered squeeze roll, wash it clean or rub its surface with a fine grit sandpaper.
