Bowed Rolls

October 20, 2006

Maxson Automatic Machinery Company can incorporate bowed rolls in the carrier system of its paper sheeters to smooth out wrinkles by inducing a spreading or widening action on the moving webs. Especially valuable when running multiple lightweight webs, a fixed bowed roll is placed before each decurl unit. The roll is designed for the application, with the amount of bow determined by the caliper range and material being sheeted. By adjusting the position of the bow, relative to the web blow, the roll tightens the center or the edges of web compensating for bagginess that can result in wrinkles.
