<p>A code-duplicating machine for security keys usable in cylinder locks with a bolt operable by a plug and with a plurality of pins operable axially and rotatably by the cut key inserted into said plug to release it and enable it to rotate, said duplicating machine comprising a cutter (6), a clamp (14) for the key (8) to be cut, and means for causing said clamp (14) and said cutter (6) to undergo mutual movement resulting in said key being cut in accordance with a predetermined code, characterised in that: a first slide (20) is mounted in the base (2) in a manner slidable parallel to the plane of said cutter (6), a support (18) is mounted on said first slide (20) in a manner rockable about an axis (32) contained within the plane of the cutter (6) and perpendicular to the axis of the key (8), a second slide (16) is mounted on said rockable support (18) in a manner slidable parallel to the axis of the key (8), the clamp (14) for retaining said key (8) is mounted on said second slide (16), first control means (48,50,52) are provided for generating the movements of said first slide (20) relative to said base (2) in conformity with the depth of a given notch to be cut, second control means (22,24,26) are provided for generating the movements of said second slide (16) relative to said rockable support (18) in conformity with the position of that given notch to be cut, a control (34) is associated with said rockable support (18) to generate its rotation movements about said axis (32) in conformity with the inclination of that given notch to be cut with respect to the axis of the key (8), and to generate the traversing movements of said second slide (16) parallel to the key axis in conformity with the type of lock pin associated with that given notch to be cut. <IMAGE></p> |
