Abstract: An assembly line system has a pallet travelling along a work top of a work table section. The table section has a track along which a cardanic chain moves to convey pucks connected to the underside of the pallet in spring-loaded manner, by means of frictional engagement between the chain and pucks. The pallet is provided with a set of castors having resilient wheels. Passageways convey the pneumatic supply necessary for operating various items of equipment along the assembly line. The assembly line system also includes an adjustable track bend. In a modification the pucks are locked in the track.
