Abstract
A cardboard sheet is cut from a continuous cardboard strip unwound from a fanfold. A conveyor advances the strip along a conveyor plane and halts the strip for cutting. A first rotary circular blade mounted above the conveyor plane is movable in alternating translation transverse thereto and can pass through or beyond the conveyor plane to cut the continuous strip to obtain a cardboard sheet. A cutting profile of a toothed second rotary circular blade mounted above the conveyor plane contacts the continuous strip of cardboard without passing beyond it so as to realize thereon a transverse score line.
