Abstract
Abstract A multi-layer industrial type woven webbing having a multiple weave construction has at least one warp end of polyamid yarn adjacent both of the selvage edges of both the upper layer of fabric and the lower layer of fabric to provide greater toughness at the edges of the webbing. Further toughness of the edges is provided by additionally adding two or more warp ends of polyamid monofilament at each selvage edge of each fabric layer.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
108 words
Woven webbing of the type having multiple weave construction having at least an upper layer of body fabric and at least a lower layer of body fabric, a first selvage edge and a second selvage edge adjacent said layers of body fabric said layers of body fabric being fabricated from polyester warp and filling yarns and having binders joining the at least one upper layer and at least one lower layer, and at least one warp yarn of nylon yarn adjacent the first and second selvage edges of the upper layer of body fabric and the lower layer of body fabric to provide greater toughness at the edges.
Claim 2
Dependent Claim
108 words
Woven webbing of the type having multiple weave construction having at least an upper layer of body fabric and at least a lower layer of body fabric, a first selvage edge and a second selvage edge adjacent said layers of body fabric said layers of body fabric being fabricated from polyester warp and filling yarns and having binders joining the at least one upper layer and at least one lower layer, and at least one warp yarn of nylon yarn adjacent the first and second selvage edges of the upper layer of body fabric and the lower layer of body fabric to provide greater toughness at the edges.
Claim 3
Dependent Claim
71 words
The woven webbing of claim 1 wherein there are two nylon warp yarns in the upper layer of body fabric adjacent the first selvage edge, two nylon yarns in the upper layer of body fabric adjacent the second selvage edge, two nylon yarns in the lower layer of body fabric adjacent the first selvage edge and two nylon yarns in the lower layer of body fabric adjacent the second selvage edge.
Claim 4
Dependent Claim
40 words
The woven webbing of claim 2 further including at least one monofilament warp filament between the selvage edges and the nylon yarns at each of the upper and lower layers of body fabric at the first and second selvage edges.
Claim 5
Dependent Claim
31 words
The woven webbing of claim 3 wherein there are two nylon monofilament filaments at each of the upper and lower layers of body fabric at the first and second selvage edges.
