Abstract
The presence of protruding filaments in a woven endless belt for the transport of tobacco or filter material in a machine of the tobacco processing industry is detected by one or more optoelectronic detectors. Signals which are generated by such detectors are evaluated to transmit a defect signal only when the detectors generate signals which were in fact initiated by protruding filaments rather than by projecting particles of tobacco or filter material, and when the number of such signals per length of the belt reaches a preselected value which warrants the generation of a defect signal.
