Abstract
Abstract A method of forming a textile having an undulating wire member therein. The method includes forming a wire which exhibits shape memory behavior into an undulating wire member, training the wire to remember its shape, causing the undulating wire member to straighten by undergoing a shape-memory transformation, securing the straightened wire member in a conventional textile and then causing the straightened wire to undergo a shape memory transformation back to the remembered undulating shape.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
107 words
A method of forming a textile with an undulating wire member therein, said method comprising the steps of: (a) forming a wire exhibiting shape memory behavior into an undulating wire member; (b) training said wire to remember its shape while it is formed into said undulating wire member; (c) causing said undulating wire member to straighten by undergoing a shape-memory transformation, thereby producing a straightened wire with a memory of an undulating shape; (d) securing said straightened wire with said memory of said undulating shape into a conventional textile; and (e) causing said straightened wire to undergo a shape memory transformation back to its remembered undulating shape.
Claim 2
Independent Claim
107 words
A method of forming a textile with an undulating wire member therein, said method comprising the steps of: (a) forming a wire exhibiting shape memory behavior into an undulating wire member; (b) training said wire to remember its shape while it is formed into said undulating wire member; (c) causing said undulating wire member to straighten by undergoing a shape-memory transformation, thereby producing a straightened wire with a memory of an undulating shape; (d) securing said straightened wire with said memory of said undulating shape into a conventional textile; and (e) causing said straightened wire to undergo a shape memory transformation back to its remembered undulating shape.
Claim 3
Dependent Claim
82 words
The method of claim 1 , wherein step (a) comprises: (a-1) providing a flat mandrel with a first series of pins spaced substantially equiangularly at a first radius with a spacing angle θ and a second series of pins spaced substantially equiangularly at a second radius with said spacing angle θ, said first and second series of pins being substantially θ/2 out of phase; and (a-2) winding said wire in an interlaced fashion about said pins to produce said undulating wire member.
Claim 4
Dependent Claim
114 words
The method of claim 1 , wherein step (a) comprises: (a-1) providing a cylindrical mandrel with a first series of pins spaced substantially equiangularly, with a spacing angle γ, along a first helical path, and a second series of pins spaced substantially equiangularly, with said spacing and angle γ, along a second helical path which has an identical helix angle to said first helical path and which is displaced axially a predetermined distance therefrom, said first and second series of pins being substantially γ/2 out of phase when viewed along an axis of said cylindrical mandrel; and (a-2) winding said wire in an interlaced fashion about said pins to produce said undulating wire member.
