ABSTRACT:
A cigarette rod making or filter rod making machine wherein the wrapping mechanism employs an endless garniture belt having an upper reach which advances first along an upwardly sloping and thereupon along a horizontal portion of an endless path. A web of wrapping material is delivered onto the upwardly sloping portion of the upper reach, and such web is thereupon converted into a tube which is draped around a rod-like filler of fibrous material. The filler is delivered by the horizontal and/or upwardly sloping lower reach of a foraminous endless belt conveyor in such a way that is reaches the web substantially at the locus between the upwardly sloping and horizontal portions of the upper reach of the garniture belt. The upwardly sloping portion of the upper reach of the garniture belt and the adjacent substantially horizontal portion of the lower reach of the endless belt conveyor define a wedge-like space which narrows in a direction toward the horizontal portion of the path for the upper reach of the garniture belt. The upwardly sloping portion of the upper reach of the garniture belt makes with a horizontal plane an angle of 3.degree.-5.degree.. The lower reach of the endless belt conveyor can be composed of two portions which make an angle of 175.degree.-177.degree..
