ABSTRACT:
Directly following application of a label (3) to the adhesive coating (5) of a backing web (2) by rolling the affixation point (8) non-contact sensing by the sensor (31) of a detector device (30) establishes whether the adhesive coating (5) is not fully covered due to mutual misorientation. In the case of such a misorientation the backing web (2) including substantially all other means of a paper processing line are halted, as a result of which the exposed adhesive coating (5) is unable to soil any further parts of the machine.
