A register control device for the cylinder of a printing machine that emits a signal when a printing plate is resting in register on one or more register pins associated with a print cylinder. The signal is communicated to a stationary evaluation unit by a magnetic field. In this regard, a magnetic field sensor is attached to the printing machine frame and is used to detect the signal and forward the signal to the evaluation unit. The evaluation unit uses the communicated signal to determine whether or not insertion of the printing plate was properly performed.

Register control device for a printing machine

The present invention generally describes register control equipment for the cylinder of a printing machine. It specifically pertains to the printing plate of sheet-fed offset printing machine that has fitted register pins. The register pins are electrically insulated with respect to the cylinder and emit a signal when a printing plate is resting in register on one or more of the pins. The signal is communicated to a stationary evaluation unit by an electrical contact adapted to contact the printing plate. The evaluation unit uses the communicated signal to determine whether or not insertion was properly performed.
