ABSTRACT:
A flat platen-type cutting and creasing press for sheet material includes a continuously moving closed loop conveyor that carries sheet gripping means in a feed direction along a generally horizontal feed path extending through a sheet loading station, a sheet unloading station, and a cutting station having die elements positioned thereat with the cutting station being positioned between the sheet loading and unloading stations. Eccentric shafts rotating at uniform speed translates platens carrying the die elements along a circular path positioned for the die elements to operatively engage and thereby fully cut a sheet moving along the feed path through said cutting station. Rotating counterbalancing weights on the eccentric shafts are disposed between points on the platens that are connected to the eccentric shafts.
