Abstract: A process for the simultaneous, constantly available provision of amounts of energy and/or signal-transmission media to a plurality of workstations circulating in the shape of an oval is described. A supply line, connected to all the workstations, is circulated with workstations. Energy and/or signal-transmissions are fed through a trailing cable which is connected to a rotary linkage which is capable of travelling back and forth on a rail within the oval in the longitudinal direction of the oval and from the rotary linkage to the supply line.
