  • Patent number: 9758306
    Abstract: A closed continuous conveyor for pallets has an upper run and a lower run, which respectively form an upper and a lower conveyor track with reversal sections in which deflecting elements are arranged, of which at least one is connected to and driven by an engine, with tension elements rotating endlessly in the upper and lower runs and in the reversal sections, which engage the deflecting elements in the reversal sections and are driven by them. At least one rotating pallet is carried by the tension elements. At least one closure element is fixed to the underside of the pallet and engages in the reversal section with a second form closure element or frictional closure element that rotates around a fixed axis of rotation. The closure element includes at least one elastic buffer component.
