Systems and methods and apparatus involving fabricating brush seals
A method for fabricating a brush seal assembly comprising, bending a first plate member to a helical shape, bending a second plate member to a helical shape, securing the first plate member to a drum, winding a wire material around the drum and the first plate member, securing the second plate member to the drum, attaching the second plate member and the first plate member to the wire, and cutting the wire to define a bristle length.
1. A system for fabricating a brush seal assembly comprising:
a drum member having an axis of rotation and a surface partially defining an outer diameter of the drum member;
an alignment portion disposed on the surface operative to align and secure a front plate member and a back plate member of a brush seal assembly along a helical curve.
2. The system of claim 1 , wherein the system comprises a winding apparatus operative to rotate the drum member on the axis of rotation and wrap a wire around the drum and the back plate.
3. The system of claim 1 , wherein the alignment portion is a channel having a helical curve profile.
4. The system of claim 1 , wherein the alignment portion includes an alignment pin operative to align and secure the front plate member and the back plate member.
5. The system of claim 1 , wherein the alignment portion includes a registration surface on the drum member.
6. The system of claim 1 , wherein the front plate member includes a surface operative to contact a registration surface on the drum member and align the front plate member with the back plate member.
7. The system of claim 1 , wherein the surface includes a cutting cavity.
8. The system of claim 1 , wherein the system includes a first clamping apparatus operative to apply a clamping force to the front plate member.
9. The system of claim 8 , wherein the first clamping apparatus is a helical shape.
10. The system of claim 9 , wherein the system comprises a second clamping apparatus operative to apply a clamping force to a wire disposed on the front plate member.
