SUBSTANCE: proposed method used in tobacco industry comprises conveying filter rods from container into cutter drum grooves. Filter rods are cut to filter segments to be unloaded from said groove as a set of filter segments by pushers connected with unloading device to be directed along unloading path, first, by said pushers and, then, by feeder to separation device. Then, said segments are transferred to belt for grouping to be arranged in the order that ensures the production of filter from segments fed from several modules. In case gaps occur at said path of unloading said filter segments from cutter drum groove caused by absence of the rod in drum groove and detected by appropriate sensor, operation of the devices located downstream, of said gap is decelerated. At the same time, operation of the devices upstream of said gap are accelerated till elimination of said gap.
