ABSTRACT:
A cutting device for sheets as well as booklets with at least one revolving blade and a conveyer device. The conveyer device with which the material to be cut is transported by the cutting knife of the cutting device, and has at least one endless conveyer element which presses onto the material. This is pressed against the material by a pressure device that is spring loaded and rests against it. This pressure device consists of individual pressure pieces, arranged in a row in the running direction of the conveyer element, each of which is spring loaded independently from the others and mobile in the direction of stress. By the independent spring responsive mobility of each individual pressure piece, the contour of the conveyer element adapts automatically to the possibly irregular contour of the material to be transported. A lateral guide device avoids shifting crosswise to the running direction under the influence of crosswise forces during the cutting process.
