Abstract (en)

[origin: EP0059041A1] In an apparatus for producing filter cigarette mouthpieces with secondary air channels, longitudinal grooves are embossed in the periphery of the filter elements by means of heated dies arranged on the inner surfaces of troughs (13-18) carried by two conveyors (1, 2). During embossing, the troughs of each conveyor co-operate in facing pairs and jointly enclose each filter portion (23).
