Abstract: An apparatus for picking up an auxiliary stack when conveying sheets in a printing machine that makes it possible to reduce constraining forces when guiding loadbearing elements. The apparatus has loadbearing elements disposed on a crossmember for the auxiliary stack, the loadbearing elements being fastened to the crossmember so as to pivot in at least two degrees of freedom.

Abstract: Device for conveying single sheets or a shingled sheet stream in a feeder region of a sheet-processing machine of a conveyor table equipped with at least one endless conveyor belt, and at least two rotatably supported deflection rollers over which the conveyor belt is guided, the conveyor belt being disposed so as to convey the sheets in a region between a sheet pile and front stops, wherefrom the sheets are transferable to a further processing location of the sheet-processing machine, includes a motor for driving the conveyor belt uncoupled from the sheet-processing machine, and a computer and control device for triggering the motor with a predetermined velocity profile exhibiting a velocity change as a function of an angular position of the sheet-processing machine; and method of operating the sheet-conveying device.
