Abstract
After the start of manufacturing, the control system provisionally calculates a cutting moment necessary to obtain a proper length of the filter rod and compares it with the basic static relationship calculated earlier, after which it makes a gradual adjustment of the cutting moment in relation to the calculated basic static relationship and determines an averaged cutting point of a filter roller considering the information about actual dimensions of the segments and their actual positioning in the roller, conveyed by a sensor. During manufacturing, the averaged cutting point is compared by the control system with the cutting moment and, in order to keep the length tolerance of the filter rod, dynamically corrected considering the information about the segments currently conveyed by the sensor.
