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.

An apparatus for lifting a signature fed on a wedge-shaped saddle to a conveyor by an upwardly and downwardly movable lifting comb, which conveyor comprises at least one pair of conveyor elements, one of them being wheel-shaped and the other one being an elongated flexible endless member which is mounted for revolving movement along an endless path. Said path is defined by deflecting means and runs along a segment of the peripheral surface of the wheel-shaped element so as to form a conveyor gap for conveying the signature lifted by said lifting comb. In a transfer station, a pressing means is provided for pressing the lifted signature to the wheel-shaped conveyor element for transferring the signature from the lifting comb to the mouth of the conveyor gap.

A device for conveying and cutting a pile of sheets with a disk-knife having an associated conveyor for continuously supplying the pile of sheets to the disk-knife, being of relatively simple construction and guaranteeing a satisfactory smooth cut acceptable for a visible surface, through a specially designed clamping member.

Device for conveying and cutting a pile of sheets

Apparatus for cutting through a pile of sheets with a revolving blade is disclosed. The apparatus comprises a relatively slowly rotatable disk-knife having a circular cutting edge and reciprocable between a cutting position and a rest position. A conveying system is provided for holding and supplying the pile of sheets to the disk-knife and carries, on a sliding carriage, a counter-knife for the disk-knife and a pair of confronting clamping members for releasably clamping the pile of sheets during the cutting operation. A common drive is provided which is synchronously interconnected with the conveying and cutting elements of the apparatus.
