Abstract
Abstract A method of constructing a low-tension wire array including the steps of arraying wires on an expandable frame expanding the wires past their elastic limit, and releasing the frame tension until each wire hangs in catenary. The wires are then placed onto an epoxied sheet and the ends cut.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
128 words
The method of assembling a wire array in a low-tension framework comprising the steps of arranging an array of wires in a substantially parallel relationship in an expandable frame with the ends of said wires affixed to the frame members, tensioning each wire of said array simultaneously by expansion of said frame members in the direction of length of said wires until the elastic limit of each of said wires of said array is exceeded, removing said tensioning by contracting said frame members until each of said wires hang in catenary, raising a substantially flat epoxy-coated planar support surface up into said array of wires until the wires contact the surface over its entire length, allowing said epoxy to cure and cutting said wires loose from said frame.
Claim 2
Independent Claim
128 words
The method of assembling a wire array in a low-tension framework comprising the steps of arranging an array of wires in a substantially parallel relationship in an expandable frame with the ends of said wires affixed to the frame members, tensioning each wire of said array simultaneously by expansion of said frame members in the direction of length of said wires until the elastic limit of each of said wires of said array is exceeded, removing said tensioning by contracting said frame members until each of said wires hang in catenary, raising a substantially flat epoxy-coated planar support surface up into said array of wires until the wires contact the surface over its entire length, allowing said epoxy to cure and cutting said wires loose from said frame.
Claim 3
Dependent Claim
14 words
The combination of claim 1 wherein said surface is a sheet of thermoplastic material.
Claim 4
Dependent Claim
27 words
The combination of claim 1 wherein each of said frame members is a threaded bar which is individually adjustable for positioning the wires relative to said bar.
Claim 5
Independent Claim
138 words
The method of assembling a wire array in a low-tension framework comprising the steps of arranging an array of wires in a substantially parallel relationship in an expandable frame with the ends of said wires affixed to the frame members, tensioning each wire of said array simultaneously by expansion of said frame members in the direction of length of said wires until the elastic limit of each of said wires of said array is exceeded, removing said tensioning by contracting said frame members until each of said wires hang in catenary, raising a substantially flat epoxy-coated planar support surface up into said array of wires until the wires contact the surface over its entire length, allowing said epoxy to cure, cutting said wires loose from said frame, and epoxy bonding said resulting wired plane to a support frame.
