US 2026/0049674 A1 · COMPACT LINE GUIDE FOR CLEAN ROOM APPLICATIONS AND PRODUCTION METHOD AND SLEEVE UNIT FOR SAME

Abstract

A method for producing a conduit for a clean room application, comprising electric cables and an elongate flexible sheath which can be moved back and forth so as to form a deflecting bend between two towers, wherein the flexible sheath has a number of parallel receiving portions, each for at least one cable, wherein each receiving portion extends in the manner of a channel in a longitudinal direction from a first end to a second end; the method comprising the steps of providing at least one cable bundle of contiguous cables and providing the flexible sheath, wherein the sheath is prefabricated and the cable bundle is introduced into a receiving portion of the prefabricated sheath, wherein the prefabricated sheath comprises at least one sleeve unit having two interacting closure profiles of a closure in order to close an open state in a dust-tight manner and the cable bundle is inserted into the opened sheath transversely to the longitudinal direction or the prefabricated sheath comprises at least one sleeve unit which is produced so as to be circumferentially closed and the cable bundle is drawn into the closed sleeve unit in the longitudinal direction.

1-30. (canceled)

An enclosure unit for an elongate flexible enclosure of a line guide, comprising:

wherein the enclosure unit forms at least one receiving means to guide at least one line and extends passage-like in a longitudinal direction from a first end to a second end,
wherein the enclosure unit is formed of plastic and has an enclosure wall comprising a flexible plastic,
wherein the enclosure unit comprises two laterally oppositely disposed functional regions, one of the functional regions being a first fixing strip and another one of the functional regions being a second fixing strip, wherein the first and second fixing strips are of mutually matching relationship to form a releasable connection, and/or wherein the enclosure unit comprises a functional region embodied as a closure including two closure strips, wherein the two closure strips extend in the longitudinal direction and cooperate to dust-tightly close an opened state of the enclosure unit, wherein in the opened state a line is introducable into or removable from the enclosure unit transversely relative to the longitudinal direction, and in a closed state of the enclosure unit the enclosure wall has a tubular form and an oval or round cross section,
wherein the first and second fixing strips and/or the two closure strips are flexurally stiffer than the enclosure wall.
