Abstract
Apparatus for transferring a rod-like filler of fibrous material of the tobacco processing industry from the underside of a foraminous suction belt conveyor to the concave upper side of a running web of cigarette paper or other suitable wrapping material upstream of the station where the web is draped around the filler and downstream of the station where the fibrous material is showered against the foraminous belt conveyor has a so-called garniture belt conveyor which advances the web along a horizontal path, and a guide which compels an upstream portion of the foraminous belt conveyor to advance above and in at least substantial parallelism with the garniture belt conveyor. The guide causes a downstream portion of the foraminous belt conveyor to slope downwardly toward the garniture belt conveyor.
