Abstract
Abstract A bundle of optical fibers for use in the manufacture of an ornamental bouquet, lamp or like device. A ribbon or juxtaposed fibers is formed with its fibers secured together along a strip extending across the width of the ribbon intermediately of its opposite ends. The ribbon is rolled laterally to bundle the fibers together and ends of the fibers at one side of the securing strip are grouped tightly together while portions of the fibers oppositely of the strip remain unconnected to flare freely outwardly of the bundle when the bundle is disposed vertically.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
189 words
The method Of making an ornamental bouquet of flared lightconducting fibers comprising the steps of: forming a ribbon of a plurality of juxtaposed light-conducting fibers; securing said fibers together with a strip of material extended across said ribbon; cutting across said ribbon through said juxtaposed fibers along two lines, one spaced away from each of respectively opposite sides of said strip, one of said lines being oblique to the longitudinal direction of said fibers at least throughout a substantial portion of its extension across said ribbon to produce fibers of progressively varying lengths according to the ornamentation desired of said bundle; removing the section of said ribbon extending between said two lines of cutting; rolling said section of ribbon from an edge adjacent the shortest of said varying lengths of fibers toward its opposite edge in a direction generally perpendicular to axial directions of the juxtaposed fibers to form at least some of said fibers into a bundle; securing said bundle against unrolling; and orienting said bundle generally vertically with said fibers extending from one side of said strip directed generally upwardly and ornamentally flared outwardly of said bundle.
Claim 2
Independent Claim
189 words
The method Of making an ornamental bouquet of flared lightconducting fibers comprising the steps of: forming a ribbon of a plurality of juxtaposed light-conducting fibers; securing said fibers together with a strip of material extended across said ribbon; cutting across said ribbon through said juxtaposed fibers along two lines, one spaced away from each of respectively opposite sides of said strip, one of said lines being oblique to the longitudinal direction of said fibers at least throughout a substantial portion of its extension across said ribbon to produce fibers of progressively varying lengths according to the ornamentation desired of said bundle; removing the section of said ribbon extending between said two lines of cutting; rolling said section of ribbon from an edge adjacent the shortest of said varying lengths of fibers toward its opposite edge in a direction generally perpendicular to axial directions of the juxtaposed fibers to form at least some of said fibers into a bundle; securing said bundle against unrolling; and orienting said bundle generally vertically with said fibers extending from one side of said strip directed generally upwardly and ornamentally flared outwardly of said bundle.
Claim 3
Dependent Claim
14 words
The method according to claim 1 wherein said strip of material is an adhesive.
Claim 4
Dependent Claim
20 words
The method according to claim 2 wherein said strip of material further includes a plastic film attached to said adhesive.
Claim 5
Dependent Claim
37 words
The method according to claim 1 wherein said one of said lines along which said fibers are cut biases said fibers at an acute angle relative to at least one of said opposite sides of said strip.
Claim 6
Dependent Claim
31 words
The method according to claim 1 wherein one of said opposite sides of said strip is disposed and directed substantially parallel to the direction of said one oblique line of cutting.
Claim 7
Dependent Claim
38 words
The method according to claim 1 wherein said one of said lines of cutting across said ribbon biases said fibers in one direction partially thereacross and is jogged to a different direction over remaining fibers of said ribbon.
Claim 8
Dependent Claim
26 words
The method according to claim 1 wherein said one of said lines of cutting across said ribbon contains a plurality of jogs in its extent thereacross.
Claim 9
Dependent Claim
29 words
The method according to claim 1 wherein portions of said fibers extending from the side of said strip opposite to said one side are grouped and secured tightly together.
