Achenbach slitting machines type HeavySlit serve for slitting stronger aluminium as well as copper and brass foils huge finish rolls in narrow strips of minimum 10 mm width. Designed either with pivoted or horizontally shiftable rewinding unit they are always tailored to the specific operation purpose. 

For each new foil slitting machine or those to be modernized, a holistic approach to perfectly synchronize mechanics, hydraulics, automation and drive technology in their complex interaction is applied.
