FIELD: machine building.
SUBSTANCE: invention relates to the method of manufacture of multi-segment filtering rods, according to which different segments placed in the relevant order, are displaced by means of feed unit on formatting band, where they are wrapped up in a paper wrapper, then they are separated into filtering rods of some length with a cutter head. A feed unit, cutter head and formatting tape are driven by separate servomotors connected by the common virtual electronic shaft, connected with a control system. Before the commencing of manufacture the information on a cut segment, length of filtering rod, the sequence of segments in the rod and constant distance between feed unit and cutter head are entered into a control system, then it evaluates a baseline static electronic ratio between driving systems of servomotors of feed unit and cutter head, and after the commencing of manufacture the control system in advance evaluates the cutting torque necessary to obtain the relevant length of the filtering rod, and compares it with a baseline static ratio calculated earlier, then it performs gradual regulation of the cutting torque with reference to a scaled baseline static ratio and determines the averaged point of cutting of filtering extruder.
EFFECT: provision of self-control of rod length reproducibility.
