Abstract

A device, for detecting a sufficient glue coating on a first surface of a paper strip to be adhesively bonded in a cigarette machine, includes a sliding plate having a plate surface engaging a second surface of the paper strip, opposite to the first surface, and over which the paper strip runs in a first direction. A plurality of capacitive sensors, for detecting presence of moisture in the glue coating, on the first surface of the paper strip, are directed toward the second surface of the paper strip, are mounted in recesses in the sliding plate and are arranged in a row extending transversely to the first direction. A control is coupled to the sensors for evaluating signals emitted from the sensors and for emitting a fault signal for controlling the cigarette machine when the moisture sensed in the glue coating is insufficient.
