Abstract
Abstract A fabric connector seam in which woven complementary seam-halves joined by a pintle are provided and in which each seam-half comprises a single and a double layer zone mechanically bound by the nature of the weave and in which the crosswise yarns of each seam-half form alternately displaced loops on one edge thereof which can be intermeshed with like loops formed on the edge of the remaining seam-half.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
124 words
A fabric connector seam having two identical seam-halves joined by a pintle in which each seam-half contains first, second and third warp systems and a single filling system, said first and second warp systems respectively providing with said filling, face and back weaves, said face weave overlying said back weave for a portion thereof providing a double layer zone and said third warp system binding said face and back weaves together in the double layer zone, and said filling system woven in folded position along an edge to enable said face weave to overly said back weave to form alternately displaced protruding loops along said edge for intermeshing with like loops formed along the edge of a like seam-half for receipt of said pintle.
Claim 2
Dependent Claim
124 words
A fabric connector seam having two identical seam-halves joined by a pintle in which each seam-half contains first, second and third warp systems and a single filling system, said first and second warp systems respectively providing with said filling, face and back weaves, said face weave overlying said back weave for a portion thereof providing a double layer zone and said third warp system binding said face and back weaves together in the double layer zone, and said filling system woven in folded position along an edge to enable said face weave to overly said back weave to form alternately displaced protruding loops along said edge for intermeshing with like loops formed along the edge of a like seam-half for receipt of said pintle.
Claim 3
Dependent Claim
94 words
A fabric connector seam-half containing first, second and third warp systems and a single filling system, said first and second warp systems respectively providing with said filling, face and back weaves, said face weave overlying said back weave for a portion thereof providing a double layer zone and said third warp system binding said face and back weaves together in the double layer zone, and said filling system woven in folded position along an edge to enable said face weave to overly said back weave to form alternately displaced protruding loops along said edge.
Claim 4
Dependent Claim
94 words
A fabric connector seam-half containing first, second and third warp systems and a single filling system, said first and second warp systems respectively providing with said filling, face and back weaves, said face weave overlying said back weave for a portion thereof providing a double layer zone and said third warp system binding said face and back weaves together in the double layer zone, and said filling system woven in folded position along an edge to enable said face weave to overly said back weave to form alternately displaced protruding loops along said edge.
Claim 5
Dependent Claim
27 words
A fabric connector seam-half in accordance with claim 2 in which said filling loops are formed of a heat settable material and are heat set into position.
Claim 6
Dependent Claim
22 words
A fabric connector seam-half in accordance with claim 2 in which the filling yarn is a four-carrier braid having a core yarn.
Claim 7
Dependent Claim
17 words
A fabric connector seam-half in accordance with claim 4 in which the filling yarn is multifilament NOMEX.
Claim 8
Dependent Claim
26 words
A fabric connector seam-half in accordance with claim 2 in which the double layer is a double plain weave bound together by the third warp system.
Claim 9
Dependent Claim
32 words
A fabric connector seam-half in accordance with claim 2 in which the seam-half is of stepped configuration so that it can be attached to a fabric by stitching the single layer thereto.
