Summary Monitoring Device for Overlapped Stream Sheet Feed to Printing Machines Envisaged in the case of a monitoring device for over- lapped sheet feed to printing machines, with a scanning roller (13) mounted such that it can rotate on a carrier above a base of sheets in overlap arrangement, whereby the carrier can be adjusted by means of a servo motor in such a way that the scanning roller rotates only when a certain number of sheets lie one on top of the other, with a sensor (14) interacting with the scanning roller (13), whereby an intermediate roller moving transversely with respect to its axis and arranged at right angles with respect to the plane of the sheets can be provided between the scanning roller and the base, is that the scanning roller (13) is mounted such that its rotation is unlimited, that the sensor (14) is designed in such a way that it registers all rotary movement of the scanning roller (13), that a device is provided to measure the distance of the scanning roller (13) or the intermediate roller to the base of the overlapped sheets, that a control unit is provided which is coupled with the sensor, the measuring device and the servo motor, that a device is provided to produce a signal characteristic for the angle of rotation of the printing machine and which is fed to the control unit, and that the control unit is designed in such a way that it monitors the overlap structure. This arrangement greatly facilitates handling. (Fig. 2)
