Apparatus for drawing and straightening at least a metal wire, comprising a drawing unit of the metal wire along a direction of advance which comprises a first motorized main roll, on part of the periphery of which first idle contrast rolls are disposed, with a smaller diameter than the first main roll. The apparatus also comprises a straightening only unit of the metal wire, independent from the drawing unit, disposed along the direction of advance and upstream of the drawing unit, the straightening only unit comprising a second idle main roll, on part of the periphery of which second idle contrast rolls are disposed, with a diameter smaller than the second main roll.

Method and device (10) to manage a coiler apparatus (11) associated with a distributor (15), in which there is at least an exit of the feeder (21) of hot or cold semi-worked metal products, and with a reel (16), both being respectively moved with suitable controlled movement and rotation means, able to manage the coiling obtaining coils with desired characteristics.

A system for producing reinforcing cages for wind turbine tower segments, wherein a reinforcing cage has in each case substantially horizontally oriented ring segments and substantially vertically oriented stiffening elements. It is proposed that the system has a receiving area which is adapted so as to receive the preferably inner, substantially horizontally oriented ring segments of the reinforcing cage, a first handling robot for supplying and positioning the stiffening elements, and a second handling robot for connecting the ring elements to the stiffening elements.

In a device, in particular machine, for producing Wiegand wire from a wire, in particular pulse wire, and a method for operating a device, the device having a first clamping chuck, a second clamping chuck, and a third clamping chuck, the wire being fed through each of the three clamping chucks, in particular so that the wire is able to be connected in a releasable and torsionally fixed manner to the three clamping chucks, in particular able to be connected to the three clamping chucks in a releasable, torsionally fixed and nonpositive manner. The clamping chucks are set apart from one another in the wire direction, and the second clamping chuck is situated between the first and the third clamping chuck in the wire direction. The second clamping chuck is rotatably mounted so that a torsion is able to be applied to a first wire section and the reverse torsion is able to be applied to a second wire section, the first wire section being situated between the first clamping chuck and the second clamping chuck, the second wire section being situated between the third clamping chuck and the second clamping chuck. The distance in the wire direction between the first and the second clamping chuck is controllable and/or regulatable with the aid of a first linear actuator, and the distance in the wire direction between the second and the third clamping chuck is controllable and/or regulatable with the aid of a second linear actuator.

Pick-up device (10) configured to selectively pick up and extract at least one bar (B) from a plurality of bars (B) disposed on a feed plane (111) and to position it on a delivery plane (12), said pick-up device (10) comprising a support arm (11) terminally provided with a pick-up head (12). The present invention also concerns an apparatus (100) for feeding bars (B) comprising the device (10) as above and a corresponding method for picking up bars (B).

Provided are a systems and methods for continuously providing a metal wire to a welding torch for manufacturing objects by solid freeform fabrication to provide continuous deposition of metal to the freeform object, especially objects made with titanium or titanium alloy wire.

A reinforcing bar binding machine capable of reliably performing a wire gripping operation includes a first movable gripping member that is displaced in a direction to contact with and separate from one side of a fixed gripping member and a second movable gripping member that is displaced in a direction to contact with and separate from the other side of the fixed gripping member. A bending portion brings the first movable gripping member and the second movable gripping member into and out of contact with the fixed gripping member. The fixed gripping member includes a shaft that rotatably supports the first movable gripping member and the second movable gripping member. Further, the bending portion includes an opening and closing pin that pushes an opening and closing guide hole provided in the first movable gripping member, and an opening and closing guide hole provided in the second movable gripping member.

The present invention relates to a metal fiber manufacturing system. The system casts molten metal as a metal fiber; collects the metal fiber in real time; transfers the metal fiber; separates normal products from defective products; and packages a predetermined amount of the normal product metal fiber. The system processes the cast metal fiber continuously or in batches, and manufactures the same, thereby having effects of improving the efficiency of the production process and obtaining significant economic benefits.
