Abstract
The matrix (17) has a coordinate array of holes (18) which have a spacing of approximately 2.54 millimetres, over its entire working surface. A punch support (8) carries the punch tools (9), with a guide block (14) below the latter having further holes aligned with those in the matrix (17). The guide block (14) and the punch support (8) can be adjusted by screws (29) cooperating with springs (30). The matrix (17) is secured in place by quick-release means, so that it can be readily interchanged with a second matrix with holes of a different diameter, the matrix hole sizings covering a range of 0.8 to 1.2 millimetres.
