Apparatus for fabricating an optical fiber ribbon

Claim 3

The apparatus of claim 1, wherein the tape is a first tape and said holding means is effective for holding the first tape having an exposed adhesive coating on which a desired group of unbound optical fibers are to be assembled in engagement with said assembly platen; and wherein said bedding means is rendered effective as said organizer is moved along said assembly platen for causing the desired group of unbound optical fibers to become embedded in the adhesive coating of the first tape preparatory to a second tape with an adhesive coating being placed over and engaged with the group of fibers embedded in the adhesive coating of the first tape to provide a bound planar array.

Claim 4

The apparatus of claim 2, wherein said assembly platen comprises: a track comprising a rigid material and having a minimum length which is greater than a maximum desired length of the planar array; a reference guide rail extending longitudinally with said track, said guide rail being effective to guide said organizer mounted on said assembly platen along a desired path; and said track including a pair of grooves formed in an upper surface of said track, being formed to a predetermined depth and extending along the length of said assembly platen, said grooves being parallel and spaced a predetermined distance apart.

Claim 5

The apparatus of claim 3, wherein said predetermined distance between said grooves is substantially equal to a desired width of the planar array, and wherein one of said grooves adjacent to said reference rail being a predetermined distance from said guide rail.

Claim 6

The apparatus of claim 4, wherein said organizer comprises: a body portion; at least one follower mounted to said body portion and adapted to engage said reference guide rail and to be moved therealong as said organizer is moved along said track; a plurality of pins attached to said body portion, said pins being effective to prevent tangling of optical fibers which become disposed in engagement with said organizer; a converging fiber guide which includes a surface which is convex in a direction of the longitudinal axis of said track and which is concave in a direction transverse to the longitudinal axis of said track, said converging fiber guide being effective to cause a plurality of substantially parallel optical fibers to converge into a planar array as said organizer is moved along said track; a plurality of bearing surfaces mounted to said body portion and adapted to engage a surface of the assembly platen and effective to support said body portion; and a fiber guide positioning means attached to said converging fiber guide and being effective to locate said planar array of optical fibers a predetermined distance from said at least one follower.

Claim 7

The apparatus of claim 5, wherein said plurality of bearing surfaces are adapted to engage a guide surface attached to said assembly platen.

Claim 8

The apparatus of claim 5, wherein said plurality of organizer pins are mounted to the body portion and extend perpendicular thereto.

Claim 9

The apparatus of claim 7, wherein said organizer pins are arranged along two intersecting planes in a V-shaped array.

Claim 10

The apparatus of claim 5, wherein said fiber guide positioning means is effective to cause the planar array of optical fibers to be positioned with respect to the first tape so that said bedding means causes the array to be embedded in the adhesive coating of the first tape between said grooves of said track.

Claim 11

The apparatus of claim 2, wherein said bedding means engages the group of unbound optical fibers after the fibers of the group have been moved together and into a planar array and prior to the group of fibers being moved into engagement with the adhesive coating of the first tape.

Claim 12

The apparatus of claim 10, wherein said bedding means cooperates with said organizer as said organizer is moved along said track to cause the unbound optical fibers to become embedded in the adhesive coating of the first tape.

Claim 13

The apparatus of claim 11, wherein said bedding means is maintained in a controlled compressive engagement with the adhesive coating of the first tape.

Claim 14

The apparatus of claim 2, which also includes a ribbon trimming device adapted to be movably mounted on said assembly platen, said device being effective for severing the first and second tapes along a longitudinal path parallel to said bound planar array of optical fibers to facilitate removal of excess lateral portions of the first and second tapes from the bound planar array to provide a planar array of desired width, said ribbon trimming device comprising: a trimmer body; at least one follower which is mounted rotatably on said trimmer body and which engages and which is adapted to be moved along said reference guide rail of said assembly platen; a pair of cutting blades secured to said trimmer body and being effective to sever the first and second tapes which bind a planar array of fibers, one of said blades being adjacent to said at least one follower; a cutting blade positioning device attached to said trimmer body which is effective to secure and position said cutting blades; and a plurality of bearing surfaces mounted to said trimmer body, said bearing surfaces being adapted to engage a surface of said assembly platen and being effective to support said trimmer body.

Claim 15

The apparatus of claim 13, wherein said plurality of bearing surfaces are adapted to engage a guide surface attached to said assembly platen.

Claim 16

The apparatus of claim 13, wherein the cutting blade which is adjacent to said at least one follower is a predetermined distance from said at least one follower, and said cutting blades are positioned in said cutting blade positioning device a predetermined distance apart by a cutting blade spacer such that said cutting blades become disposed in said grooves of said assembly platten when said at least one follower of said trimmer becomes engaged with said assembly platen reference guide rail.
