Abstract
An apparatus for forming a sector of an annular component having an arrangement for securely retaining at least a portion of a blank mountable thereon. The retaining arrangement is adapted for leaving a portion of the retainable blank accessible. A punch is provided having an external surface contour shaped to correspond to the shape of all or a part of the profile of the sector of the annular component from a trailing edge to a leading edge and/or from a leading edge to an inlet edge. The apparatus has a cooperating forming arrangement for forming the profile of the sector of the annular component from the leading edge to the inlet edge. The retaining arrangement is adapted for forming a clamping boundary enclosing the accessible part of the blank to be formed by the punch.
