Abstract: An embossing tool is employed for embossing a plurality of cable marking rings. The tool comprises upper and lower embossing heads which are movable against each other. The cable marking rings to be embossed are held on two parallel holding pins which are supported movably in a support body by means of elastic bushings. One of the embossing heads is equipped on each one of two opposing sides with a centering fork comprising centering slots in which the holding pins are centered during the embossing process.

Abstract: A cable marking strip comprises a strip of an adhesive tape having a self-adhering bottom side and carrying an inscribable marking section. The beginning of the inscribable marking section is located at a distance from the adjacent front end of the adhesive tape to define an unlettered, transparent starting section of the strip which may be pressed onto the cable without soiling the marking section or smudging the lettering applied to it.

Abstract: A marking device for applying split rings provided with a mark onto electrical wires of different diameters is constituted by a supply rod for supporting a series of marking rings, an application shoe formed at one end of the rod and having a flared configuration, the bottom of the shoe being provided with a recess communicating with the free end of the shoe and converging toward the supply rod, and the front side of the shoe being split by a V-shaped notch into two prongs which resiliently accommodate the shoe to wires of different diameters.
