Abstract: In a process for the manufacture of an optical ribbon conductor from several optical conductors, the outer circumference of at least one optical conductor (LW2) is coated with a first coating material (FC). The optical conductor (LW2) and at least another optical conductor (LW3) are arranged adjacent to each other in their longitudinal direction (OA) and are formed into a ribbon conductor and coated with a second coating (BC), so that a gap (S) results between the two adjacent optical conductors which is not occupied by an optical conductor. The position of at least one of the optical conductors (LW2, LW3) within the ribbon conductor (LWB) is controlled relative to the coating thickness (D) of the second coating material (BC). The second coating material (BC) can then dependably be removed after manufacture without also removing the first coating material (FC).

Abstract: An optical transmission element (BL1, BL2) shows at least two optical fiber sub-units (BL1, BL2) which are combined by means of a common plastic covering (BSA). To the plastic covering (BS1, BS2) of the respective optical fiber sub-unit (BL1, BL2) at least one binding agent (HM1, HM2) is applied which causes the adhesion of the plastic matrix of the common second covering (BSA) of the optical transmission element (BL12) to the respective plastic matrix of the coverings (BS1, BS2) of the at least two optical fiber sub-units (BL1, BL2).

Abstract: When enveloping an electrical or an optical conductor, the method applies a radiation-reactive resin having photoinitiators with an absorption maximum onto the conductor and then the resin is cured by subjecting it to a radiation of a wavelength preferably in the wavelength range for the absorption maximum of the photoinitiators. The apparatus for enveloping includes an arrangement for applying the resin followed by a radiation source for applying the radiation of the desired wavelength that falls into the range of the absorption maximum of the photoinitiators of the resin.

Abstract: A method and an apparatus for forming a waveguide conductor ribbon by passing several light waveguides through a through-opening so that as the waveguides are passed through the opening, they are coated by a liquid coating material, which creates a drag force current for moving the waveguides through the opening. The diameter of the light waveguides and/or the position of the light waveguides inside the ribbon conductor is determined and the width of the through-opening of the coating apparatus is modified on the basis of the measured diameter value and/or on the basis of the size of any gap between the fibers to optimize the amount of drag current forces being produced.

Abstract: A method and apparatus for forming color identifiers for a lead includes a mechanism for surrounding an outer surface of a lead, which may be an optical lead or an electrical lead, with a primer coating, a mechanism for injecting either drops of paint or a line of paint into the still unhardened coating followed by a mechanism for drying the primer coating with the integrated paint.

Abstract: A plurality of light waveguides are conducted side-by-side through a coating arrangement that will surround the waveguides and supply them with a coating material for enclosing the light waveguides to form a ribbon conductor. The light waveguides are guided freely running both proceeding as in the coating arrangement so that they essentially come into contact only with the coating material. A drag flow or entrained flow of the liquid coating material contributes to a self-centering of the light waveguides and is produced by the longitudinal motion of the light waveguides in the coating material of the arrangement.
