Abstract
Abstract In-line application of liquid adhesive to an optical fiber (10) while it is being wound onto a drum (14) is accomplished by a tube (58) interconnected with a pressurized adhesive source of supply (70). An end (60) of the tube provides adhesive in a beadlike strip which wets the drum or underlying winding layer just under the fiber lower surface before it is laid down onto the drum.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
67 words
Method of forming a filament wound pack on a drum with adjacent winding layers releasably adhered to one another, comprising the steps of: axially rotating the drum with an end of the filament secured thereto to wind the filament on the drum; and continuously wetting the surface of the underlying winding with a liquid adhesive just under and immediately prior to a filament winding being laid down.
Claim 2
Dependent Claim
67 words
Method of forming a filament wound pack on a drum with adjacent winding layers releasably adhered to one another, comprising the steps of: axially rotating the drum with an end of the filament secured thereto to wind the filament on the drum; and continuously wetting the surface of the underlying winding with a liquid adhesive just under and immediately prior to a filament winding being laid down.
Claim 3
Dependent Claim
26 words
Method as in claim 1, in which the adhesive is laid down in a beadlike strip having a width approximately equal to that of the filament.
Claim 4
Dependent Claim
26 words
Method as in claim 1, in which the adhesive is provided to the underlying window in an amount functionally related to the filament winding linear velocity.
Claim 5
Dependent Claim
43 words
Method as in claim 1, in which the wetting with adhesive is accomplished by locating the open end of a tube underneath a filament about to be wound onto the drum, pressurizing adhesive through the tube to be deposited onto the underlying winding.
Claim 6
Dependent Claim
38 words
Method as in claim 4, including the further step of establishing a relative movement parallel to the drum axis between the drum and the tube in a direction to advance the drum wetting in synchronism with filament winding.
Claim 7
Dependent Claim
99 words
Apparatus for applying a liquid adhesive while an optical fiber is being wound onto a drum from a storage spool, comprising: a pulley wheel guiding the fiber toward the drum; a hollow tube mounted with an end located between the optical fiber and the drum at a point after it has been guided by the pulley wheel and before the said fiber is wound onto the drum; and a source of pressurized liquid adhesive connected to the other tube end providing a minimal amount of adhesive to continuously wet the underlying surface on which the fiber is being wound.
Claim 8
Dependent Claim
99 words
Apparatus for applying a liquid adhesive while an optical fiber is being wound onto a drum from a storage spool, comprising: a pulley wheel guiding the fiber toward the drum; a hollow tube mounted with an end located between the optical fiber and the drum at a point after it has been guided by the pulley wheel and before the said fiber is wound onto the drum; and a source of pressurized liquid adhesive connected to the other tube end providing a minimal amount of adhesive to continuously wet the underlying surface on which the fiber is being wound.
Claim 9
Dependent Claim
20 words
Apparatus as in claim 6, in which the pulley wheel has a circumferential groove within which the fiber is received.
Claim 10
Dependent Claim
44 words
Apparatus as in claim 6, in which the tube and pulley wheel are unitarily mounted, and means for providing relative movement between the drum and the unitary pulley wheel and tube radially of the drum and along a path parallel to the drum axis.
Claim 11
Dependent Claim
20 words
Apparatus as in claim 8, in which the tube and pulley wheel are adjustably positionable with respect to each other.
Claim 12
Dependent Claim
27 words
Apparatus as in claim 6, in which means interconnect the tube and pressurized adhesive source for supplying adhesive in a continuous beadlike strip from the tube end.
Claim 13
Dependent Claim
21 words
Apparatus as in claim 10, in which said means supplies adhesive in an amount functionally related to the fiber winding velocity.
Claim 14
Dependent Claim
20 words
Apparatus as in claim 10, in which the strip is of a width approximately equal to that of the fiber.
