Claim 0:
1. A multi-layer braided article comprising
a core extending along a first axis (z);
a braid wound circumferentially around the core and extending along the first axis, wherein the braid is folded back over itself to form a first layer and a second layer each extending along the first axis; and
a wrapper laid over the first layer of the braid and extending circumferentially around the first axis,
wherein the wrapper defines an edge of the first layer about which the braid is folded back along the first axis to form the second layer;
wherein the edge is a first edge (18a) and the wrapper (18) is a first wrapper, wherein the first wrapper extends a first axial length (18d) from the first edge, the multi-layer braided article further comprising:
a second braid (31) on top of the first braid and extending along the first axis, wherein the second braid is folded back over itself to form a first layer and a second layer extending along the first axis; and
a second wrapper (38) laid over the first layer of the second braid and extending circumferentially around the second braid around the first axis;
wherein the second wrapper defines a second edge (38a), that is located at the same axial location as the first edge, about which the second braid is folded back along the first axis to form the second layer of the second braid;
wherein the second wrapper extends a second axial length (38d) that is less than the first axial length; and
wherein the first layer of the second braid extends from the second edge by a length that is greater than the first axial length, such that the first and second braids form a conical portion of the multi-layer braided article.
