Abstract
Abstract The invention relates to a method of feeding a plurality of optical waveguides into a clamping device, between whose clamping jaws the optical waveguides are clamped in a side-by-side relationship in one plane. A simple and easily operatable method, which in subsequent production stages ensures the preservation of the relative position of the individual optical waveguides, is obtained in that the clamping device is placed such by means of form-locking elements in a fixed position at a housing member between two sorting forks of the sorting device that feed-in channels of the sorting forks are in alignment with a take-up channel of the clamping device, in that thereafter the optical waveguides are placed in the sorting forks and in the take-up channel which has previously been widened by loosening its clamping jaws, in that the optical waveguides are then pressed together by means of a slide-film material which is inserted into the threading channels and/or the take-up channel, in that the clamping action of the clamping jaws causes the optical waveguides to be clamped and finally the clamping device together with the optical waveguides contained therein is removed from the sorting device.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
163 words
A method of feeding a plurality of optical waveguides into a clamping device having clamping jaws, the optical waveguides being clamped between said clamping jaws in one plane. wherein (a) the clamping device is applied by means of form-locking elements in a fixed position at a housing member between two sorting forks of a sorting device having threading channels so that feed-in channels of the sorting forks are in alignment with a take-up channel; (b) the optical waveguides are placed in the sorting forks and in the take-up channel which has previously been widened by loosening the clamping jaws of the clamping device; (c) the optical waveguides are then pressed together by means of insertion of a slide-film material which is inserted into the threading channels and/or the take-up channel so that the clamping action of the clamping jaws causes the optical waveguides to be clamped; and the clamping device is taken from the sorting device together with the optical waveguides inserted therein.
Claim 2
Independent Claim
163 words
A method of feeding a plurality of optical waveguides into a clamping device having clamping jaws, the optical waveguides being clamped between said clamping jaws in one plane. wherein (a) the clamping device is applied by means of form-locking elements in a fixed position at a housing member between two sorting forks of a sorting device having threading channels so that feed-in channels of the sorting forks are in alignment with a take-up channel; (b) the optical waveguides are placed in the sorting forks and in the take-up channel which has previously been widened by loosening the clamping jaws of the clamping device; (c) the optical waveguides are then pressed together by means of insertion of a slide-film material which is inserted into the threading channels and/or the take-up channel so that the clamping action of the clamping jaws causes the optical waveguides to be clamped; and the clamping device is taken from the sorting device together with the optical waveguides inserted therein.
Claim 3
Dependent Claim
37 words
A method as claimed in claim 1, wherein the optical waveguides are pressed by the slide film material onto stop bottom surfaces selected from the group consisting of the threading channels, the take-up channels and combinations thereof.
Claim 4
Dependent Claim
92 words
A sorting device for performing the method as claimed in claim 1 or 2, which includes a basic member (18) with two spaced apart facing sorting forks (8, 9, 19, 20) having threading channels (10, 11, 25) that are in alignment with each other, a clamping device being fixed between the sorting forks (8, 9, 19, 20) by means of form-locking elements (13, 14, 37, 38, 39, 40) said clamping device having adjustable clamping jaws (5, 6, 34, 35) in a take-up channel (1) which is in alignment with the threading channels.
Claim 5
Dependent Claim
53 words
A device as claimed in claim 3, wherein the form-locking elements (13) of the sorting device (7, 21) engage form-locking elements (14, 37, 38) of the clamping device (2, 26), which are provided for the purpose of positioning the clamping device on arrangements for the manufacture of a splice of the waveguides (3).
Claim 6
Dependent Claim
23 words
A device as claimed in claim 4 wherein one of the side walls (27) constituting the threading channels (25) can be pivoted outwardly.
Claim 7
Dependent Claim
43 words
A device as claimed in claim 4 wherein the slide-film material (22) is provided on a slide holder (31) of the sorting device (21), which is slidable against the action of a spring (34) along longitudinal bearings (32, 33) of the sorting device.
Claim 8
Dependent Claim
61 words
A device as claimed in claim 4, wherein the form-locking elements are constituted by pins provided on the sorting device (21) one pin projecting into an associated bore (37) of the clamping device (26) and the other pin projecting into a slotted hole (38) of the clamping device (26), which extends in a direction towards the connecting lines of the pins.
Claim 9
Dependent Claim
