When sheeting light weight board, the sheets have a tendency to turn under at the edges entering the stacker. What can I do?

Try to give the sheet some added rigidity by using edge turners and crimpers. Edge turners (or “shoes”) flare the edges of the sheet in the delivery system. Crimpers are placed in the center of the web path to corrugate the sheet, giving it added stiffness.

When using edge turners and crimpers be careful about the placement of top tapes near them. If the tapes are too close to the edge turners or crimpers they will crease or mark the sheet.
