Paper types with higher grammages can break at the folding edge during folding. Creating a groove removes material along the folding edge, producing an ideal folding location. The SuperFax groove machines are suitable for all higher paper grammages and all production involving solid board. Perforations enable parts to be separated (torn off), e.g. for coupons, entry tickets or vouchers.
Grooves and perforations require accuracy and an exact process. SuperFax machines are renowned for their ease-of-operation and simple yet precise adjustment.
