Abstract
A cigarette making machine includes a suction conveyor arranged to carry a tobacco filler stream which is substantially wider than its depth, a suction chamber situated downstream of the zone in which the filler stream is formed on the conveyor or received by the conveyor and arranged to induce an air flow through the filler stream and also along the filler stream, whereby tobacco from peaks in the filler stream tends to be carried forward and to be attracted to the conveyor by suction drawn through the conveyor in regions of less tobacco, and including structure for subsequently reducing the width and increasing the depth of the filler stream before the filler stream is conveyed to a rod-forming pad of the machine in which the filler stream (possibly after trimming) is enclosed in a wrapper web to form a continuous cigarette rod.
