  • Printing press with infrared dryer safety system
    Patent number: 6732651
    Abstract: A printing press with an infrared dryer unit is provided with a safety system for detecting overheating and sheet jamming conditions. The safety system has a temperature sensor disposed to directly detect the temperature of a passing printed sheet and to generate an output signal proportional to the detected temperature. As the printed sheets pass by the sensor, the sensor output signal contains a pulse for each passing sheet. A controller monitors temperature readings derived from the output signal of the temperature sensor for identifying a sign of overheating. The controller also determines whether there is an interruption in the flow of sheets by monitoring the pulses in the sensor output signal. In the case the sensor fails to provide pulses for a predetermined time, the controller generates a control signal indicating the detection of an interruption in the sheet flow.
