Abstract (en)

[origin: US4753433A] Device for monitoring imbricated sheets stream fed to a printing machine, including a scanning roller rotatably mounted on a carrier above a base of imbricatedly arranged sheets, the carrier being adjustable by a servomotor so that the scanning roller rotates only when a given number of sheets are arranged on top of one another, a sensor cooperatively associated with the scanning roller, and an intermediate roller movable transversely with respect to its axis and substantially perpendicularly to the plane of the sheets, the intermediate roller being disposed between the scanning roller and the base, comprising a device for measuring the distance of at least one of the scanning roller and the intermediate roller to the base of the overlapped sheets, a control unit coupled with the sensor, the servomotor and the measuring device and a device for producing a signal characteristic of an angle of rotation of the printing machine, the signal being fed to the control unit, the control unit having a device for monitoring the imbricated sheet structure, the scanning roller being mounted so that its rotation is unlimited, and the sensor having a device for detecting all rotational movements of the scanning roller.
