<p>An automatic machine for curving, in a spatial configuration, thin and rectilinear metal elements, more especially metal wires. The present invention provides an automatic machine for curving thin and rectilinear metal elements of constant thickness of the wire strip or tube kind. This machlne comprises a distributor means 13 through which a metal element to be curved (1) may be moved with a stepped feeding movement, a bending means (14) which is situated downstream and in the vicinity of the outlet of the distributormeans (13) and which may, on the one hand, be driven with an angular rotational movement about an axis (Y) perpendicular to the feed direction of the metal element and, on the other hand be moved with a reciprocal movement over a rectilinear path (X) parallel to this axis (Y). This machine further comprises means for generating a relative angular rotational movement between th bending means (14) and the metal element (1), around a second axis. (Z) merging with the feed direction of the metal element. Preferably, these means cause the bending means (14) to rotate about the metal element (1) which is secured against rotation.</p> |
