Abstract
Abstract A alignment device used during the winding of optical fibers on a takeup drum, a portion of the periphery of the takeup drum is arranged to form an incline plane or surface which angles inwardly towards the axis of rotation of the drum. The inclined surface provides arrangement of the individual fiber windings into aligned engagement with adjacent fibers arranged on the periphery of the drum.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
114 words
A fiber-aligning device of the type used to align a plurality of fiber windings, the device comprising: a rotatable shaft, a takeup drum rotatably mounted on the shaft, a member integrally mounted on the periphery of the drum wherein the member is incongruous to the remaining peripheral surface of the drum, an incline surface formed on the incongruous peripheral member, the inclined surface being inclined toward the axis of rotation of the drum, whereby the individual fiber windings arranged on said drum are automatically shifted into aligned engagement with adjacent windings on the drum due to the inclined surface being formed at a predetermined angle relative to the axis of rotation of the drum.
Claim 2
Dependent Claim
114 words
A fiber-aligning device of the type used to align a plurality of fiber windings, the device comprising: a rotatable shaft, a takeup drum rotatably mounted on the shaft, a member integrally mounted on the periphery of the drum wherein the member is incongruous to the remaining peripheral surface of the drum, an incline surface formed on the incongruous peripheral member, the inclined surface being inclined toward the axis of rotation of the drum, whereby the individual fiber windings arranged on said drum are automatically shifted into aligned engagement with adjacent windings on the drum due to the inclined surface being formed at a predetermined angle relative to the axis of rotation of the drum.
Claim 3
Dependent Claim
21 words
A fiber-aligning device as in claim 1 wherein the incongruous peripheral member extends upwardly from the peripheral surface of the drum.
Claim 4
Dependent Claim
50 words
A fiber-aligning device as in claim 1 further comprising: a recess formed in the peripheral surface of the drum, the incongruous peripheral member mounted in the recess, the inclined surface formed on the incongruous peripheral member such that the inclined surface extends above the remaining peripheral surface of the drum.
Claim 5
Dependent Claim
17 words
A fiber-aligning device as in claim 3 where the incongruous member is removably mounted in the recess.
Claim 6
Dependent Claim
50 words
A fiber-aligning device as in claim 1 further comprising: a recess formed in the peripheral surface of the drum, the incongruous member comprising at least one pin mounted within the recess, the pin including an inclined surface mounted thereon and being inclined toward the axis of rotation of the drum.
Claim 7
Dependent Claim
21 words
A fiber-aligning device as in claim 1 wherein the angle of inclination of the inclined surface is between 10* and 30*.
