Abstract
Abstract An electric current supply conduit comprising a metal support rail of substantially U-shaped cross-section forming an open longitudinal channel. The support rail is provided with longitudinally extending current conductors fastened at the opposite side walls of the support rail. The ends of the current conductors are bent to project angularly, preferably perpendicularly with respect to the longitudinal direction of the support rail inwardly into said open channel of the support rail.
