Abstract
Abstract A method for manufacturing an optical cable includes simultaneously introducing a light waveguide and filling material into a chamber of a central element with the waveguide having an excess length. Preferably, the central element is moved axially and rotated on the axis and the light waveguide and filling material are passed through a tube which is inserted in the chamber as the central element is moved relative thereto.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
86 words
A method for manufacturing optical cables having a central element with at least one open chamber receiving at least one light waveguide having an excess length and a filling compound, said method comprising the steps of providing the central element having the open chamber, and simultaneously introducing the light waveguide with a filling compound into the chamber in a single step including guiding the waveguide and filling compound through a common filling tube to be discharged from an end of the tube into the open chamber.
Claim 2
Independent Claim
86 words
A method for manufacturing optical cables having a central element with at least one open chamber receiving at least one light waveguide having an excess length and a filling compound, said method comprising the steps of providing the central element having the open chamber, and simultaneously introducing the light waveguide with a filling compound into the chamber in a single step including guiding the waveguide and filling compound through a common filling tube to be discharged from an end of the tube into the open chamber.
Claim 3
Dependent Claim
29 words
A method according to claim 1, which includes subsequent to introducing the fiber and filling compound into the chamber, closing the chamber by simultaneously extruding a cladding layer thereon.
Claim 4
Dependent Claim
33 words
A method according to claim 1, wherein the step of providing includes moving the central element axially and rotating the element on its axis as the step of simultaneous filling the introducing occurs.
Claim 5
Dependent Claim
19 words
A method according to claim 3, which includes the step of stripping excess filling compound from the central element.
Claim 6
Dependent Claim
22 words
A method according to claim 4, which includes after the step of stripping, closing the chamber by extruding a cladding layer thereon.
Claim 7
Dependent Claim
36 words
A method according to claim 3, wherein the step of introducing the filling compound and the light waveguide includes introducing the filling compound faster than the longitudinal movement of the corresponding chamber of the central element.
Claim 8
Dependent Claim
26 words
A method according to claim 1, wherien the step of introducing includes positioning the common filling tube with the discharge end projecting into the respective chamber.
Claim 9
Dependent Claim
21 words
A method according to claim 7, wherein the filling tube has a cross-section that roughly corresponds to that of the chamber.
Claim 10
Dependent Claim
65 words
A method according to claim 1, wherein the step of providing the central element provides an element with a plurality of chambers, and the step of introducing includes providing a separate filling tube with a discharge end for each chamber and guiding waveguides and filling compound through the filling tubes to be discharged from the discharge ends into each chamber of the plurality of chambers.
Claim 11
Dependent Claim
37 words
A method according to claim 1, wherein the step of providing includes moving the central element axially and rotating the central element on its axis relative to the filling tube which is held in a fixed position.
