A slitter is a round metal blade that rotates and slits each web lengthwise. The slitters are evenly spaced across the machine to create the desired sheet width. Each slitter is equipped with suction to reduce the amount of airborne dust. If the final product needs to be three-hole punched, a special perforation unit can be added and enabled. After the slitting blades, the webs enter a cross-cutter to be cut width-wise. The cross-cutter is a large roll with blades on it that cuts each web to the proper sheet length as it rotates. Once cut, the sheets are moved using a series of belts.
The belts deliver the cut sheets into pockets. The number of pockets must correlate to the number of slitting blades. Machines can range from 2 to 16 pockets. As the sheets pile up in each pocket, they are held in place by a finger. Once enough sheets have been accumulated, the assembly removes the stacks of sheets from the pockets and places them on a pair of conveyors. The conveyors split the reams into two streams, and send them to be wrapped.
