A process for the blanking of metallic drawer guides, in particular metallic guides for so-called "self-closing" drawers, by a transfer machine, comprising at least one shearing phase from a strip (10) to shape the contours of a preform (12), a phase of separating said preform (12) from said strip (10) to shape a single flat preform (12) in an elongated rectangular form, suitable for producing a whole (13, 14) with two opposed right and left-side guides of a drawer, with additional molding and shaping phases of said flat preform in two parts in the shape of a "Z" facing each other in a specular manner while being centrally joined, and a separating phase by blanking the said two parts so as to shape two guides having an essentially Z-formed cross section (30,40) with an inclined ramp (31,41) in a terminal area (12a). <IMAGE> |
