A data line that is designed as a coaxial cable and has a line core that extends in a line longitudinal direction. The line core has at least one conductor surrounded at least by insulation and is surrounded by a multi-layer shielding foil, which has a non-conductive layer and a conductive layer. In an overlap region, a free end edge overlaps a further partial region, wherein additionally a conductive connection of the conductive layer at the end edge to the further partial region is formed such that a transverse current flow perpendicular to the longitudinal direction within the conductive layer is enabled. The conductive connection is formed optionally as a conductive strip and/or by a beveled end edge. In particular, the data line is a data line shielded exclusively via the shielding foil. The data line is used in particular in a motor-vehicle electrical system.

An object of the present invention is to make it easy to bind a plurality of electric wires together. An electric wire bundle includes an electric wire group and a binding portion. The electric wire group includes a bundle portion in which at least a portion of a plurality of electric wires in an extension direction is bundled together. The binding portion formed by supplying a fluid binding portion forming material to an outer circumferential portion of the bundle portion in strip-shape in a form in which the bundle portion can be maintained in a bundled state and curing the binding portion forming material. Such a bundle can be formed by discharging the fluid binding portion forming material from a nozzle to the circumference of a bundle portion of a plurality of electric wires supported by an electric wire supporting portion, and curing the fluid binding portion forming material.

A fabric sleeve in the form of a strip of material having compatible attachment members along its lateral edges, is applied to a cable by a device located at a site where the cable can be introduced into a conduit. The device includes a beam carried by a post. The beam carries a plurality of formers which receive the sleeve and the cable from rolls and which progressively fold the sleeve around the cable. The beam also carries an attachment device which receives the sleeve and cable from the formers and which connects the attachment members of the sleeve to confine the cable therein. The attachment device can be opened so that the sleeved cable can be removed. The device is operated at the site until the sleeved cable reaches a downstream installation site and the process is repeated at that downstream site.
