Abstract
A conveyor, particularly for feeding tobacco to a cutting drum, comprises a number of articulated slats passing around sprocket wheels. The slats are identical and each has extensions and recesses. The extensions of one slat enter the recesses of the next adjacent slat, and are retained by a pin passing through the extensions of adjacent slats. The underside of each extension has a flat surface for contacting a support plate and the top face of the sprocket teeth contact the slats so that the flat underside of each extension is not contacted by the sprocket wheel, in order to maintain a constant pitch as the band travels around the sprocket wheels. In this way the spacing between the conveyor and a dead plate positioned to remove tobacco from the band as it passes over a sprocket wheel remains constant.
