1. Device for copying a part depicted by a template (1) with lengthwise axis, comprising a two-dimension copier comprising a lengthwise carriage (4) movable along the lengthwise direction (6) and a cross-wise carriage (11) movable along a cross-wise direction (12) at right angle to the lengthwise direction, and also comprising a feeler device (2) for the template (1) comprising a valve (25) controlling the two-dimension copier as well as at least one feeler rod (21) acting on this valve (25), characterized in that the feeler device (2) comprises a bar (22) on which the feeler rod (21) is so arranged as to have the rod (21) extend substantially in the plane defined by the lengthwise end cross-wise directions, a first swinging link (23) between the bar (22) and the body of the valve (25) the swinging axis of which lies in parallel relationship with said plane defined by the lengthwise and cross-wise directions, and a push-rod (24) to let the feeler rod (21) act on the control valve (25), and in that the copying device comprises means (29, 33) so arranged as to modify the direction of the feeler rod (21) relative to the lengthwise axis of the template (1) about a second swinging link (28) swinging axis of which lies at right angle to said plane. |
