An apparatus for working bars includes a plurality of containing devices disposed adjacent and parallel to each other with an oblong development in respective longitudinal directions to contain a respective bundle of bars. At least one work station is located downstream of the containing devices. The work station includes at least one removal device to remove at least one bar from one of the containing devices, at least one drawing unit configured to move the bars in a direction of feed parallel to the longitudinal directions, and at least one bending device configured to bend the bars At least one drive member is associated with the work station, configured to move work station in a transverse direction with respect to the longitudinal directions in order to take the removal device into correspondence with one or the other of the containing devices, which are substantially fixed in position.

Method for the continuous production of mesh mats made of steel wire having a plurality of parallel longitudinal wires that are welded to transverse wires extending in a manner spaced apart from one another, wherein hot- or cold-rolled wire material is used as the longitudinal and transverse wires, wherein the longitudinal wires are stretched in a stretching apparatus while being fed to the welding operation, wherein the longitudinal wires are drawn through the stretching apparatus by means of a capstan drum, and wherein the transverse wire material is also stretched in a separate stretching apparatus while being fed to the welding operation, and an installation for carrying out the method.

A binding machine includes a wire feeding unit, a curl forming unit, a cutting unit, and a binding unit. The binding unit includes a locking member that includes a first hook and a second hook and that locks the wire by moving the first hook toward the second hook. The locking member includes a locking part that locks the wire in a state in which the first hook has been moved toward the second hook, and an unlocking part that makes it possible for the first hook to be movable away from the second hook with such an amount of movement that the locked wire does not come off between the first hook and the second hook.

A multifunction work apparatus includes a drawing and yielding assembly and at least one of either a wire guide assembly, a straightening assembly, or a finishing assembly. The drawing and yielding assembly includes a contrast roll, rotatable idly around its axis of rotation, and at least two motorized rolls positioned on the periphery of said contrast roll.

A method and a system for handling slender bodies in a semi-finished production plant includes a cutting station separating slender bodies from a continuous wire, a finishing station of the head ends of the slender bodies, a dimensional verification station downstream of the finishing station, and transporting equipment transporting the slender bodies between stations. At or upstream of the cutting station a marking unit applies a reference marking on the slender bodies, which working identifies an original attitude including angular position. The transporting equipment includes gripping and locking assembly, locking at least the angular position of the reference mark to a relative reference system of the transport equipment. Upstream of the finishing station is a detecting and storing unit for data of the angular position to the relative reference system. A unit determines the original attitude of the slender bodies using the data in the dimensional verification station.

A collision-proof spring transfer takes place in the process, which comprises a continuous transfer of coil springs from the pipeline through an exit opening of the pipeline into assigned spring receptacles, and an automatic prevention of any re-entry of coil springs that have passed through the exit opening in the direction of the spring receptacle and rebound from the region of the spring receptacle back into the pipeline.

The present invention discloses a positioning apparatus for positioning a spring product fed from a spring coiling machine. The positioning apparatus includes a first guiding panel having a first guiding surface for guiding the spring product and the first guiding surface have a length and a width; and a plurality of first mechanical holding members arranged on the first guiding surface in a direction of the length of the first guiding surface for optionally supporting and holding a first part of the spring product.
