A delivery for a sheet-processing machine for keeping the extent thereof required downline from the delivery pile as short as possible, includes a frame and grippers revolvable, during operation, along a gripper path within the frame. The grippers seize sheets at a location on the gripper path and drag the sheet along sections of the gripper path in a transport direction. A first switching element is provided, for defining a first end of a first one of the sections of the gripper path located downline with respect to the transport direction. A second switching element defines a second end of a second section of the gripper path located downline with respect to the end of the first section. The first switching element is provided on the frame, and the second switching element is provided on a guide part fixed to the frame, and serves for determining a section of a course of the gripper path.

Delivery for a sheet-processing machine

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 method for controlling and regulating a dryer in a rotary printing press having a varnishing device for varnishing printing stock processed in the printing press, includes measuring the intensity of a microwave signal after the microwave signal has interacted with varnished and dried printing stock fed through the rotary printing press; from the measured radiation intensity of the microwave signal, forming a status variable representing a measure of the degree of drying of the printing stock; and varying drying power provided by the dryer as a function of the formed status variable; and a device for performing the method.
