Abstract
Abstract A knitted selvage is formed along an otherwise woven ribbon by tying off loops of filling thread inserted into successive sheds of warp threads. A primary selvage thread is drawn through each loop of filling thread along with only one of two auxiliary selvage threads, the auxiliary selvage threads being drawn alternately through successive loops with the primary selvage thread.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
48 words
A ribbon comprising longitudinally-extending warp threads, loops of filling thread extending transversely of and woven through said warp threads, a primary selvage thread knitted through each filling thread loop, and first and second auxiliary selvage threads each knitted through alternate filling thread loops with said primary selvage thread.
Claim 2
Dependent Claim
48 words
A ribbon comprising longitudinally-extending warp threads, loops of filling thread extending transversely of and woven through said warp threads, a primary selvage thread knitted through each filling thread loop, and first and second auxiliary selvage threads each knitted through alternate filling thread loops with said primary selvage thread.
Claim 3
Dependent Claim
35 words
The ribbon defined in claim 1, in which each loop of filling thread is knitted through an adjacent loop of filling thread along with the primary selvage thread and one of the auxiliary selvage threads.
Claim 4
Dependent Claim
16 words
The ribbon defined in claim 1, in which the auxiliary selvage threads are of different diameters.
Claim 5
Dependent Claim
15 words
The ribbon defined in claim 1, in which the auxiliary selvage threads are different yarns.
Claim 6
Dependent Claim
20 words
The ribbon defined in claim 1, in which at least one of the auxiliary selvage threads is a textured yarn.
Claim 7
Dependent Claim
15 words
The ribbon defined in claim 1, in which the auxiliary selvage threads are unshrunk yarns.
Claim 8
Dependent Claim
70 words
In a method of manufacturing a woven ribbon which includes forming successive sheds of warp threads and looping a filling thread into such successive sheds, the improvement comprising alternately knitting first one and then another of at least two auxiliary selvage threads into successive loops of the filling thread, respectively, along with a separate primary selvage thread which is knitted through each loop to form a selvage to deter raveling.
Claim 9
Dependent Claim
70 words
In a method of manufacturing a woven ribbon which includes forming successive sheds of warp threads and looping a filling thread into such successive sheds, the improvement comprising alternately knitting first one and then another of at least two auxiliary selvage threads into successive loops of the filling thread, respectively, along with a separate primary selvage thread which is knitted through each loop to form a selvage to deter raveling.
Claim 10
Dependent Claim
37 words
In the method defined in claim 7, positioning the auxiliary selvage threads at the top and bottom of each shed, respectively, and changing the respective positions of the auxiliary selvage threads as the next shed is formed.
Claim 11
Dependent Claim
33 words
In the method defined in claim 7, knitting each loop of filling thread into the previously-formed loop of filling thread along with the primary selvage thread and one of the auxiliary selvage threads.
