Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
62 words
An arch-wire cable having a non-circular cross section comprising: a plurality of wire strands, each having a non-circular cross section, twisted together along a longitudinal axis defined by the cable; and an outer region on each of said wire strands complementing adjacent wire strand outer regions so that substantially plane surfaces are defined thereby developing the desired noncircular archwire cable cross section.
Claim 2
Dependent Claim
62 words
An arch-wire cable having a non-circular cross section comprising: a plurality of wire strands, each having a non-circular cross section, twisted together along a longitudinal axis defined by the cable; and an outer region on each of said wire strands complementing adjacent wire strand outer regions so that substantially plane surfaces are defined thereby developing the desired noncircular archwire cable cross section.
Claim 3
Dependent Claim
14 words
The arch-wire cable of claim 1 in which said non-circular cross section is rectangular.
Claim 4
Dependent Claim
13 words
The arch-wire cable of claim 2 in which said rectangular cross-section is square.
Claim 5
Dependent Claim
21 words
The arch-wire cable of claim 1 in which each of said wire strands is permanently deformed to said non-circular cross section.
