Method and device for controlling and regulating a dryer located downstream of a varnishing unit in a rotary printing press

摘要

A method for controlling and regulating a dryer in a rotary printing press having a varnishing device for varnishing printing stock processed in the printing press, includes measuring the intensity of a microwave signal after the microwave signal has interacted with varnished and dried printing stock fed through the rotary printing press; from the measured radiation intensity of the microwave signal, forming a status variable representing a measure of the degree of drying of the printing stock; and varying drying power provided by the dryer as a function of the formed status variable; and a device for performing the method.
