A displacement device for a machine for processing flat printing materials includes a slide displaceable along a displacement path in and counter to a thrust direction, and being divided along the thrust direction into two slide parts. A drag joint forms a mutual connection between the slide parts. The drag joint has a joint axis extending perpendicularly to the displacement path. A machine for processing flat printing materials, such as a sheet-processing rotary printing press, is provided with the displacement device.

A delivery for a machine processing flat printing materials includes a suction belt conveyer having conveying runs forming a support surface. To remove rejects or proof sheets as required, the delivery transports the materials along a transport path over a stack that is otherwise built up and transfers the sheets to the support surface. The physical position of the support surface can be varied while maintaining its generatrix. Therefore, the support surface can be adjusted in each print job to a working position in which secured transfer of removed printing materials to the suction belt conveyer is ensured. In a particular configuration, a latching device is provided that permits the conveying runs to escape from their working position in the event of a jam. Preferably, the latching device has a latching pin and a latching recess.

Delivery for a machine processing flat printing materials

A delivery of a sheet-processing printing machine has a sheet-pile stacking station whereon a safety guard is provided which is suspended from a pivot pin and, at least during a regular sheet-pile forming process, provides a view of a downline top edge of the sheet pile, as viewed in the processing direction. In this regard, the safety guard is constructed so that it is swingable together and swingable apart in the manner of a hinge, via a hinge pin disposed parallel to the pivot pin; and a machine for processing flat printing materials, and a sheet-processing printing machine, respectively, equipped with the delivery.

Delivery for a machine for processing sheet-like printing materials, in particular, a printing machine

A device for removing proof sheets and reject sheets from a side of a delivery of a sheet-processing machine includes a collecting container for accommodating removed sheets therein in an operating position of the container, the container being displaceable into a park position wherein it is located above the delivery; and a sheet-processing machine, in particular, including the sheet-removing device.

A device for braking sample and defective sheets of a machine for processing sheet-like printing materials includes a sheet-guiding part for guiding a sheet therealong, a roller resting on the sheet-guiding part and being movable at least in a vertical direction, for braking a sheet guided between the sheet-guiding part and the roller; and a machine for processing sheet-like printing material, such as a printing machine, including the braking device.

A suction belt conveyor for a sheet processing machine includes an operationally revolving endless suction belt having, at an outer side thereof a filigree structure formed by indentations, the suction belt being formed with penetrating bores terminating in the indentations. In a variation of the foregoing, the suction belt conveyor for a sheet processing machine includes an operationally revolving endless suction belt formed with pores distributed in longitudinal and transverse directions of the suction belt, so that the suction belt is air permeable.

A device for depositing paper sheets, in particular on a sheet pile or stack in a delivery of a printing machine, includes a revolving belt, a drive motor for driving the revolving belt separately from any other drive system, and at least one suction device having a discretely effective suction action, the suction device being disposed on the revolving belt, the revolving belt being constructed as a toothed belt for transmitting torque and synchronicity between the drive motor and the suction device; and a method of operating the depositing device.

Individual sheets are singled out in a delivery of a sheet-fed rotary printing press. The delivery has a chain delivery with gripper bars extending transversely to the sheet-transport direction. The gripper bars are disposed on revolvingly driven transport chains and carry spaced apart sheet grippers disposed side by side. The sheet grippers grip the leading edges of the sheets and slave them to a main sheet pile. The gripper release is subject to an adjustable control for delayed sheet release, so that selected sheets may be transported beyond the main sheet pile. Revolvingly drivable suction tapes suction-grip the sheets which are released by the grippers with the delay, and they transport those sheets in the transport direction across and beyond the main sheet pile and onto a single sheet depository. The sheet depository is movably disposed in or on the printing-press frame. The suction tapes have upper suction surfaces at a raised position which extend between the sheet grippers. The grippers delay the sheet release until at least a leading region of the respective sheet is located above the suction tapes.
