Abstract
Abstract A line guide for a fishing rod having a circular laminate (14) of resin-impregnated graphite fibers and a linear foot laminate (13) of resin-impregnated graphite fibers. The foot is attached to the circular laminate by winding some of the fibers (14) of the circular laminate underlying the foot and others (14') overlying the foot, and then heat-curing the assembly to produce a monolithic line guide and foot structure (12).

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
60 words
A monolithic line guide and mounting foot for a fishing rod comprising a circular laminate of wound resin-impregnated graphite fibers and linear foot laminate of resin-impregnated graphite fibers heat-welded to one side of said circular laminate in substantial parallelism to the axis thereof, some of the graphite fibers of said circular laminate underlying said foot and others overlying said foot.
Claim 2
Dependent Claim
60 words
A monolithic line guide and mounting foot for a fishing rod comprising a circular laminate of wound resin-impregnated graphite fibers and linear foot laminate of resin-impregnated graphite fibers heat-welded to one side of said circular laminate in substantial parallelism to the axis thereof, some of the graphite fibers of said circular laminate underlying said foot and others overlying said foot.
Claim 3
Dependent Claim
26 words
A line guide and mounting foot as defined in claim 1, wherein the ratio of graphite fibers to resin is about 60% to 40% by volume.
Claim 4
Dependent Claim
16 words
A line guide and mounting foot as defined in claim 1, wherein the resin is epoxy.
Claim 5
Dependent Claim
26 words
A line guide and mounting foot as defined in claim 3, wherein the ratio of graphite fibers to resin is about 60% to 40% by volume.
Claim 6
Independent Claim
78 words
The method of making lightweight line guide for a fishing rod comprising the steps of winding uncured resin-impregnated graphite fibers into a circular laminate, positioning a linear foot laminate of uncured resin-impregnated fibers exteriorly in contact with one side of said circular laminate and substantially parallel to the axis thereof, winding additional uncured resin-impregnated graphite fibers overlying said circular laminate and said linear laminate, and heat-curing the assembled laminates to produce a monolithic line guide and foot structure.
Claim 7
Independent Claim
78 words
The method of making lightweight line guide for a fishing rod comprising the steps of winding uncured resin-impregnated graphite fibers into a circular laminate, positioning a linear foot laminate of uncured resin-impregnated fibers exteriorly in contact with one side of said circular laminate and substantially parallel to the axis thereof, winding additional uncured resin-impregnated graphite fibers overlying said circular laminate and said linear laminate, and heat-curing the assembled laminates to produce a monolithic line guide and foot structure.
Claim 8
Dependent Claim
21 words
The method as defined in claim 5, wherein said linear laminate is formed into longitudinally concave contour during said heat-curing step.
Claim 9
Dependent Claim
22 words
The method as defined in claim 6, wherein the ratio of graphite fibers to resin is about 60% to 40% by volume.
Claim 10
Dependent Claim
12 words
The method as defined in claim 7, wherein the resin is epoxy.
Claim 11
Dependent Claim
22 words

Claim 13
Independent Claim
111 words
The method of making a plurality of lightweight line guides for fishing rods comprising the steps of providing axially abutting dies forming circular winding grooves at the joints and having aligned longitudinal slots in their peripheries, winding uncured resin-impregnated graphite fibers around said grooves into a circular laminate, positioning a continuous linear foot laminate of resin-impregnated graphite fibers in said aligned slots, winding additional uncured resin-impregnated graphite fibers overlying said circular laminate and said linear laminate, heat-curing the assembled laminates, cutting the linear foot between joints to provide a plurality of monolithic line guide and foot structures, and separating the dies at the butt joints to allow removal of said structures.
