Abstract: The invention relates to a wire feed station of a wire shaping machine, said station including grooved rollers functioning in pairs and rotating in reverse directions with respect to each other. The wire is clamped between said rollers by these moving closer to one another. Both rollers of the same pair of driving rollers are supported at the front of the same bearing block unit, said bearing block being elastically deformable to absorb a relative movement of the rollers. Preferably, said bearing block also supports an endless transmission screw on which are engaged a couple of transmission wheels coaxial with the driving rollers which they drive into rotation. More particularly, a bearing block is deformed so that a relative movement of the rollers results in a rotation-deformation of the bearing block about the transmission screw axis.

Abstract: The invention relates to a shaping station of a metal wire shaping sequence machine, a machine wherein a wire feed station supplies the wire along a travel axis through a bending nose which brings the wire in front of tools of a bending head which can be moved about the wire travel axis. The bending head is supported by an annular arm centered on the travel axis, and mounted to rotate about said travel axis. Preferably, the annular arm, with the guiding in rotation thereof by rollers and a toothed ring, are mounted on a support plate positioned vertically and perpendicularly to the wire travel axis. In addition, the support plate can be moved in horizontal and vertical translation in a plane perpendicular to the wire travel axis, which also is the arm rotation axis.
