An apparatus for conveying sheets in a printing press makes reliable sheet guiding possible with a low outlay on material and at low cost and includes an apparatus for conveying sheets in a printing press having at least one conveyor element for a sheet along a conveying path and at least one guide element for the sheet in the conveying direction, at least one elongate spring element being provided as a guide element.

Apparatus with springs for conveying sheets in a printing press

A method for conveying sheets through a printing machine and an apparatus for conveying the sheets permit adaptation of a sheet brake to various sheet thicknesses by reducing a speed of the sheets in the direction of advance by bringing the sheets individually one after another into contact with at least one suction element moved in the direction of advance, and by holding each sheet by the action of a suction apparatus on the suction element along a conveying section, dependent upon the sheet thickness, the suction action of the suction element along the conveying section is changed locally.

Method for conveying sheets through a printing machine and apparatus for implementing the method

A sheet-processing machine includes a conveyor for transporting processed sheets at a processing speed and for releasing the sheets for braking to a depositing speed. A braking element serves for the braking of the released sheets to the depositing speed. A drive is provided for the braking element, and a drive connection is provided for connecting the drive to the braking element. Further included are an overrunning clutch in the drive connection, and a brake for retarding the braking element.

Sheet-processing machine with a sheet brake

A delivery for a machine for processing flat printing materials includes sheet brakes for accepting sheets fed in a processing direction at an acceptance level and for releasing the sheets at a surrender level. The sheet brakes are adjustably disposed for varying the acceptance level and the surrender level. A machine is provided for processing flat printing materials, having the delivery.
