Abstract
A process of forming a turbine engine seal includes the steps of: providing a flat strip of material; roll forming the flat strip of material forming an asymmetric profile in the flat strip of material; coiling the formed asymmetric profile into an overlapping ring shape; cutting the circular shape to a predetermined length; and joining ends of the predetermined length forming the seal. The seal includes at least two peaks that are formed on opposing sides of a gap. The at least two peaks contact opposing sides of a U shaped profile at a zero radius. The asymmetric profile includes a circular shape and the ends are joined.

A process of forming a turbine engine seal comprising the steps of:
- providing a flat strip of material;
- roll forming the flat strip of material to form an asymmetric profile in the flat strip of material wherein the asymmetric profile is defined by a U shaped profile having a pair of opposing ends to define a gap, at least two peaks formed on opposing sides of the gap, the at least two peaks directly contacting the opposing sides of the U shaped profile at a zero inside radius;
- coiling the formed asymmetric profile into an overlapping ring;
- cutting the circular shape to a predetermined length;
- and
- joining ends of the predetermined length forming the seal.
A process of forming a turbine engine seal comprising the steps of:
- providing a flat strip of material;
- roll forming by continuously bending the flat strip of material in a plurality of passes to form an asymmetric profile in the flat strip of material wherein the asymmetric profile is defined by a U shaped profile having a pair of opposing ends to define a gap, at least two peaks formed on opposing sides of the gap, the at least two peaks directly contacting the opposing sides of the U shaped profile at a zero inside radius;
- coiling the formed asymmetric profile into an overlapping ring;
- cutting the circular shape to a predetermined length;
- and
- joining ends of the predetermined length forming the seal.
