Patent ID: 7762388

Claim:
A belt of a chain conveyor, comprising: two longitudinally parallel chains and a series of transverse bars which form a transport surface and connect the two chains, wherein each chain is formed by adjacent links, flanked in a plane of the belt by a lateral member, each link being U-shaped with diverging wings provided with holes suitable for housing said transverse bars, said link being provided with an appendage suitable for transmission of motion, characterised in that the link has a lateral appendage placed beyond the hole on an external wing of said diverging wings in relation to the plane of the conveyor belt as a continuation of the same and which, immediately after the hole, diverges outwardly for a section and subsequently bends in the opposite direction with respect to the direction in which the external wing extends, presenting a section parallel to the wings and finally a section which curves inwardly, so as to have overall a complete involute profile in a horizontal plane.
