Abstract:
1. A method of compensation of momentary lacking of filter segments in a manufacturing line of multi-segment filters used in tobacco industry, comprising the steps of: a) transferring filter rods from a container to flutes on a cutting drum, b) cutting the filter rods into filter segments with cutters, c) removing from one of the flutes a set of filter segments with pushers connected to an out-feeding unit and guided along an out-feeding path that is configured to feed out sets of filter segments from said flutes of the cutting drum, first by the pushers and then by a delivery unit to a separating device, d) transferring the set of filter segments from the separating device onto a grouping tape with said set of filter segments arranged in a series with required filter segments fed from several modules, and e) detecting an occurrence of a gap on said out-feeding path caused by the lack of a filter rod in the one of the flutes of the drum, and slowing down the operation of units situated downstream of the gap, while simultaneously accelerating the operation of units situated upstream of the gap, until detecting a moment of an elimination of the gap, further including in said step e), slowing down the delivery unit, the separating device, and the grouping tape, and accelerating the cutting drum with cutters and the out-feeding unit.
