Abstract: A transfer system comprising a closed rail circuit and pallets circulating on the rails of the circuit. Each pallet comprises at least two wheels which are designed to be supported by the rails of the circuit and are driven by a belt. The respective wheels comprise an axle to which a first roller is mounted and a second roller is rotatably mounted on the periphery of the first roller by a bearing. The system reduces the wear of the drive belt and the rollers when the pallet is stationary by permitting the first rollers to be rotated by the continuously moving belt when the pallet is stopped.
