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.

Apparatus for lifting and conveying a signature fed on a wedge-shaped

A device for 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.

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.

This disclosure relates to a continuous sheet feeder in which a stack of sheets arranged sheet-by-sheet are transported by conveyor belts from a lower loading tray, around a reversing cylinder and onto a discharge tray. In the region of the discharge tray, the conveyer passes between two guide rollers the longitudinal axes of which are arranged parallel to the axis of rotation of the reversing cylinder. The two guide rollers in the discharge tray are laterally movable with respect to each other whereby the inclination of the stack of sheets resting in the discharge tray can be automatically adjusted so that the upper sheet in the stack is always maintained in a horizontal disposition regardless of the format or size of the sheets, or their sheet-by-sheet arrangement.
