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.

Abstract: A conveyor mat built up of plastic intermediate modules and end modules, each module is made up of a plurality of equally spaced-apart hinge plates having hinge loops at the two ends thereof, the hinge plates of a module being coupled to each other by means of a rib asymmetrically located between the hinge loop openings which are located opposite each other, the ends of the hinge plates on a longitudinal side of a module being located between the ends of the hinge plates of a module adjacent in the longitudinal direction of the mat, the hinge loops of the two modules being coupled to each other by way of a hinge pin extending through the hinge loop openings. In operation, when the conveyor mat is driven in a first and second, opposite, direction, a sprocket wheel meshes with a side face of the rib and, respectively, the opposite hinge loop of a module. Through these measures, a conveyor mat is obtained whose modules can have an extremely slight length, up to 0.5".

Abstract: Sprocket wheels for use in chain conveyors, for instance, are preferably of a divisible construction so as to enable each wheel to be removed from the shaft separately. Also, on the basis of considerations of hygiene, the outer side surface of such a wheel is preferably entirely flat when used in the food or beverage industry. Existing divisible wheels are either flat on the outside, but expensive, or not flat and cheap because they are made by injection molding. The synthetic sprocket wheel according to the invention is flat and cheap and comprises two wheel halves with axial planes abutting against each other, each wheel half consisting of two interconnected parts, made by injection molding, abutting against each other through a radial side face, with the cavities and ribs necessarily present for the injection molding process being located in the interior of the wheel half.
