The apparatus of the present invention is utilized to treat a wrapped rod-like filler, particularly that consisting of a tow of filamentary filter material which is impregnated with droplets of triacetin of another softening agent that sets more rapidly and/or more reliably in response to heating. The wrapped filler is severed to yield a series of discrete sections, such as filter mouthpieces for use in filter cigarettes. In accordance with the invention, the wrapped filler is or successive sections of the wrapped filler are heated upstream or downstream of the severing station, preferably in a casing containing an elongated guide for the running wrapped filler or for successive discrete sections of the wrapped filler.
