摘要

The device (10) has a front side (12) and a rear side (14) associated with at least one sensor (110) for detecting the distance of a print material (16) close to the control element; an air flow field can be produced across its front side. The sensor is arranged on the rear side of the control element, via which sample energy can pass into at least a partial area of the control element. An Independent claim is also included for a sheet printing machine with an inventive device.
