  • Patent number: RE38543
    Abstract: A conveyor chain manufactured from plastic, which is adapted to move at higher speeds than has been conventional heretofore and which is consequently particularly suitable to be used in a conveying system together with a conveyor mat to take over products from this mat or feed them to it. The chain has as a specific property that the front edge and the rear edge of the bearing surface of the chain link are of curved, preferably elliptically-shaped design in the plane of the bearing surface, that the single hinge eye at the rear edge of the bearing surface has an upper surface which extends in the same plane as the bearing surface and which engages through a convexly shaped end in a correspondingly shaped recess in the bearing surface of the adjacent link coupled thereto through the hinge pin. By these measures the transition of products to and from the chain proceeds extremely smoothly at high speeds too.
