Abstract
A folding machine comprises at least one folding unit including a plurality of conveyor belts (12), a stop member (14) extending transversely of the conveyor belts, a plurality of folding rolls disposed below the conveyor belts and extending parallel thereto, a folding blade adapted to be moved within a gap defined by the folding rolls, and a detector device (light barrier 16). The folding machine is characterized by a length-of-path pulse generator (22) coupled to the conveyor belts (12), a presettable counter (24) coupled to the length-of-path pulse generator (22), the start input (26) of said counter being connected to the detector device (16) and the distance between the detector device (16) and the stop member (14) at least equalling the length of the longest sheet to be handled, and a logic circuit (30, 36, 38) adapted to start the folding blade driving means (21) only upon the counter (24) reaching a predetermined count and upon the terminal edge of a sheet having passed the light barrier.
