Abstract The invention relates to a method of, and to a device for, checking cigarettes (12) during the production or packaging of the cigarettes (12), a push rod (35) being displaced axially in the direction of a cigarette end, with the result that, in the event of the incorrect formation or absence of a cigarette (12), the push rod (35) assumes a position other than an ideal position. The invention is based on the problem of improving the operation of checking cigarettes and of configuring this operation such that it is less susceptible to malfunctioning.This problem is solved by a method according to the invention in that an electric, magnetic or electromagnetic field assigned to a sensor (32, 53) is influenced in dependence on the position of the push rod (35), a signal which corresponds to the push-rod position being generated as a result of said field being influenced. The invention also relates to a device for implementing said method.
