Patent ID: 7111487

Claim:
Deforming apparatus for forming a curve in a deformable material strip, the apparatus comprising: a first member comprising a first member body and a first deforming portion, the first deforming portion extending in a first direction between a first deforming end and a second deforming end; and a second member comprising a second member body and a second deforming portion; wherein the first and second members are arranged to receive a deformable material strip between them in a second direction along the length of the deformable material strip and transverse to the first direction; the first and second members are movable relatively towards each other to a first relative position to deform the deformable material strip with the first and second deforming portions; the first and second members are movable relatively away from each other to a second relative position; and when the first and second members are in the first relative position, the first deforming end of the first deforming portion is closer to the second deforming portion than the second deforming end of the fist deforming portion is to the second deforming portion such that the deformable material strip is being curved in a first plane defined by the first direction and the second direction and without the deformable material strip being curved in a second plane orthogonal to the first plane and parallel to the second direction.
