    Abstract: An apparatus (31) for forming an annular part (53) comprising a punch (2) having a forming end with an external surface (32) shaped to correspond to the shape of the annular part (53). The apparatus further comprises a clamping arrangement (3, 5) for clamping a large diameter end of a preform (4) and a gripping arrangement (6, 7) for adjustably gripping a small diameter end of the preform (4). An actuation system is provided for facilitating relative coaxial movement only between the punch (2), the clamping arrangement (3, 5) and the gripping arrangement (6, 7).
