Abstract:
1. A method of deforming a thin walled body comprising: (i) holding the body gripped securely in a holding station; and (ii) whilst gripped in the holding station engaging tooling to deform the peripheral wall of the body at a predetermined wall zone, the tooling comprising internal and external tooling and being provided at a tooling station which is adjacent the holding station during deformation; wherein the predetermined wall zone is co-aligned with the tooling by rotation of the body about an axis prior to securing at the holding station and wherein the tooling station is provided with a cam formation arranged such that relative movement of the tooling with respect to the cam formation in the axial direction of the body causes the tooling to move to engage the peripheral wall of the body.
