Question:

We recently sheeted an order of coated paper, and had lots of problems due to static. Do you have any suggestions for sheeting coated stock?

Answer:

If the problem is in the cutting section, such as the web wrapping around the squeeze roll or the knife revolver, an old trick is to mount a cotton felt across the infeed of the sheeter and then wet it. The dampness of the felt will help to neutralize static, and prevents jam-ups in the cutting section.

If the problems are occurring at the stacker, try introducing compressed air prior to the sheets entering the pile. By introducing a layer of air between sheet packets, static can be overcome. On MAXSON sheeters, the use of air at the pile has increased speeds by more than 200 fpm (60 mpm).
