Abstract (en)

Filters of composite type for tipping cigarettes are manufactured on a twin track machine (1) with two garniture sections (6). Groups (4) of filter plugs (5) having different filtration properties are ordered in succession end to end and advanced lengthwise along feed directions (X1, X2) extending substantially parallel with one another and through a station (14) where each succession of groups (4) passes along a garniture tongue together with a plugwrap and is formed into a continuous rod (15). The two rods (15) proceed toward a rotary cutting head (16) by which they are divided up on a given cutting line (T) into single composite filters (2). To ensure that all the single composite filters turned out on both tracks will be identical, the axial position of each rod (15) is adjustable along the approach to the cutter head, by way of a feedback loop (19).
