Typically, a cross-cutter comprises a rotating roll equipped with a knife, which cuts a material web transverse to the direction of motion, generally in identically large sections (formats).

In order to allow various cut lengths (formats), the knife drive must have a motion profile, which during the cut moves the knife in synchronism with the belt – and outside the cutting range specifies suitable deceleration or acceleration rates before the velocity is synchronized again with the belt for the next cut. The saw is synchronized with the material using the position sensing function of an upstream feed drive or using a measuring wheel.
