Abstract

A distributor for use in cigarette rod making machines has a magazine for a supply of shredded tobacco, a carded drum which draws from the magazine a continuous layer of tobacco shreds, and a device which homogenizes the layer of the drum adjacent to the magazine and comprises a strip-shaped barrier extending transversely of the layer and having a grooved surface adjacent to the exposed side of the layer and a second surface which faces the magazine and intercepts those shreds which extend beyond the grooved surface. The barrier is reciprocated transversely of the layer by a motor, and a paddle wheel is provided to return the piled-up shreds into the magazine. The carding of the drum consists of longer and shorter pins or needles which alternate with each other in the circumferential as well as in the axial direction of the drum. The layer which is homogenized during travel along the grooved surface of the barrier is thereupon converted into a narrow stream which is ready for trimming and/or wrapping into a cigarette paper web.
