Abstract
Conveyor belt for cigarettes or other delicate articles which has flights which extend across its width and are formed with rounded ends so as not to present any sharp edges to damage the articles. The belt is formed from three thicknesses of polyester web, i.e. a middle layer which is flat, and two outer layers, one of which is impressed with rounded shapes forming the flights and the other of which is impressed with angular shapes forming drive teeth. The forming may be carried out by pressing each layer between suitable heated rollers. The layer having the conveyor flights is preferably so formed that the flights do not extend to the extreme edges but leave a narrow edge margin which can be continuously bonded to the assembly comprising the other two layers. Two layer belts may also be constructed on the same principle, for example by omitting the inner flat layer in the case of a conveyor and drive belt, or by omitting one of the layers in the case of a belt for conveying or driving only, and reinforcing wires may be incorporated between the two layers.
