A binding machine includes a wire feeding unit configured to feed a wire to be wound on an object to be bound, a binding unit configured to twist the wire wound on the object to be bound, a curl guide configured to curl the wire being fed by the wire feeding unit, an inductive guide configured to guide the wire curled by the curl guide toward the binding unit, and a retraction guide part configured to retract the wire to a downstream side of the binding unit with respect to a feeding direction of the wire that is fed by the wire feeding unit in a direction of curling the wire by the curl guide.

A reinforcing bar binding machine includes a first movable gripping member that is displaced in a direction to come in contact with and separate from one side of a fixed gripping member. A second movable gripping member is displaced in a direction to come in contact with and separate from the other side of the fixed gripping member; and 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. In addition, 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.

An apparatus for handling bars includes a store provided with one or more containing elements, with a respective bundle or group of bars positioned in each. A feed station is located downstream of the store and configured to transfer the bars to a destination station. A removal device of the bars is associated with the feed station and is configured to remove the bars from at least one containing element of the store and transfer them onto the feed station. Movement means of the store, suitable to take at least one of said containing elements into correspondence with the removal device, are also included.

A method and apparatus for rebar cage construction is disclosed. A computerized controller operates an apparatus that automates parts of the rebar cage formation process. The computer controls motors for rotating the barrel and operating a wagon containing spiral coil wire. Initial rods are placed on a plurality of latitudinal conveyors. Dual cage ring assemblies are placed on the latitudinal conveyors, and notches or slots within the cage rings engage with the initial rods. The conveyors rotate the dual cage ring assemblies and a rod dispenser places a rod in additional notches. The rods, when completely installed, form a barrel structure. A wagon containing spiral coil wire is then moved longitudinally while the conveyors rotate to wrap the spiral coil wire around the barrel, to form a spiraled rebar cage.

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.

An apparatus to make a wire mesh with longitudinal wires and transverse wires, on each occasion having a reciprocal pitch defined according to requirements is provided, and includes a first feeder, a second feeder and a welding unit functionally coordinated to make the desired wire mesh.

A handling apparatus including a support plane configured to support a plurality of metal products with an oblong development, and handling devices configured to pick up a metal product from a pick-up zone of the support plane and to deliver it to a delivery zone. Movement devices are associated with the support plane configured to distribute the metal products on the support plane and to move them toward the pick-up zone. The handling devices comprise a plurality of transfer arms provided with magnetic holding elements in order to magnetically hold one of the metal products.

The present invention relates to machines, systems and processes for feeding longitudinal wires (2) for mesh (6) production. Welding of longitudinal wires (2) with transverse wires (4) at welding unit (57) produces mesh (6). Longitudinal wires (2) are controllably rotated around their longitudinal axes to selected angles, and restrained until their welding with transverse wires (4), thus negating effects of residual curvature from roller straightener (36) and resulting in mesh (6) produced planar with distortion stresses effectively neutralized. A wire collector (79) releases a first longitudinal wire (2) for guided travel laterally to a receptacle (45). A rotator unit (71) simultaneously controllably rotates this wire, while the collector (79) simultaneously receives the length of the next longitudinal wire. Particular rotator units (71) facilitate such operation. In some versions an advancement roller assembly (120) proximate to the welding unit (57) may advance longitudinal wires (2) through the welding unit, freeing a longitudinal wires carrier (31) to return to the longitudinal storage (32) and to receive a next set of longitudinal wires.

An automated technique facilitates winding a stator, such as a stator for a submersible motor of an electric submersible pumping system. According to an embodiment, needles are placed in slots of the stator and a sensor system, e.g. a camera-based vision system, is used to determine the positions of the needles. This data is provided to a control system programmed to assign a predetermined wiring pattern to the needle positions. Based on this predetermined wiring pattern, an automatic feeder system moves a feeder guide into position adjacent the appropriate needles. The automatic feeder system is then operated to feed magnet wire into the corresponding stator slot at the corresponding needle position(s) to achieve a desired winding pattern.

A steel bar transverse stepping conveying equipment is provided, including a base, and a front movable clamp area and a rear fixed clamp area arranged on the base. The front movable clamp area and the rear fixed clamp area are connected by a rear fixed clamp area connecting guiderail mechanism for relative translation. A method for controlling the steel bar transverse stepping conveying equipment is further provided. The steel bar transverse stepping conveying equipment is provided with a plurality of clamp mechanisms. A front-movable-clamp-area clamp clamps the steel bar and shifts the steel bar to a next position step by step; then the steel bar is clamped by a rear fixed clamp area clamp, and the front-movable-clamp-area clamp is released and returned to an original position; and the previous action is repeated until the stepping conveying of the steel bar is completed.
