The basis of the programmed belt consists of a drawn iron structure. The structure supporting the gas cylinders rotates over the base frame. This structure is made up of a sequence of tubes placed at a fixed distance and connected to three rows of chains. Its rotation is made by two shafts on which three crowns are connected and through the crown, shaft, gearbox and motor coupling, the entire structure is allowed to rotate by one step. By being placed between the transversal tubes, the products can travel at periodic and uniform distance intervals, moreover, collisions and the consequent noise pollution caused by the rolling of inclined planes by gravity are avoided.
