1. A method for production of a line guide for a clean room application, with electric lines and an elongate flexible enclosure which is reciprocatingly displaceable with formation of a direction-changing arc between two runs, wherein the elongate flexible enclosure has a plurality of parallel receiving means for at least one respective line, wherein each receiving means of the plurality of parallel receiving means extends in a passage in a longitudinal direction from a first end to a second end; the method comprising:
providing at least one line bundle of interrelated lines; and
providing the elongate flexible enclosure,
wherein the elongate flexible enclosure is prefabricated and the at least one line bundle is introduced into a receiving means of the plurality of parallel receiving means of the prefabricated elongate flexible enclosure, wherein the at least one line bundle includes a wire bundle comprising at least two twisted wires each having its own insulation, wherein the at least one line bundle does not have its own respective outer sheath, and
wherein the prefabricated elongate flexible enclosure comprises at least one enclosure unit having two cooperating closure profiles of a closure for dust-tightly closing an opened state and the at least one line bundle is introduced transversely to the longitudinal direction into the opened enclosure; or
wherein the prefabricated elongate flexible enclosure includes at least one enclosure unit which is produced peripherally closed and the at least one line bundle is drawn into the closed enclosure unit in the longitudinal direction; and
wherein the at least one line bundle includes an outward separating layer comprising a slidable material, which at its outside includes a fluoropolymer.
