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.

A coil end shaping apparatus shapes a plurality of edgewise bent portions that are bent in the edgewise direction in a lead wire portion extending from one end of a coil, and includes first and second shaping dies capable of approaching each other to shape the edgewise bent portions provided on the base end side with respect to the edgewise bent portion e4 that is the closest to the free end side among the plurality of edgewise bent portions, and a third shaping die capable of cooperating with the second shaping die to shape the edgewise bent portion that is the closest to the free end side.

A machine for forming RFID antennas includes a support structure provided with a support for an RFID substrate and a plurality of forming pegs having vertical axes fixed with respect to the support and arranged above it to define a predetermined path for a wire configured to form the RFID antenna The machine has a wire feeding system that has a wire guide element and a handling assembly, a pair of grippers arranged at ends of the path and operable to assume a closed position, in which the wire is blocked, and an open position, in which the wire is released, and a movable structure carried by the support structure and provided with a thrust element movable vertically between an upper position in which it allows the wire to be wound around the pegs and a lower position in which it deposits the formed antenna on the substrate.

A self-furring welded wire mesh for reinforcing generally planar concrete and stucco structures is formed of a matrix of longitudinally and transversely extending wires disposed about a first common plane and welded together at their intersections. A selected plurality of the longitudinally extending wires each define a plurality of generally V-shaped spacing furrs therein extending generally perpendicular to the first plane with the bottoms of the furrs being disposed in a second plane spaced from the first plane a distance substantially equal to one-half of the predetermined thickness of the concrete panel. The spacing furrs in the selected longitudinally extending wires are located so as to be longitudinally and transversely staggered along the mesh. The spacing furrs are formed by pushing portions of the selected longitudinal wire perpendicular to the axis of the wires while holding an upstream portion thereof in a fixed disposition so as to form these without damaging or thinning the wires along the spacing furrs.

Machine for working bars, suitable for working at least one bar having a mainly oblong development; the machine comprises at least two support sliders, of which at least one is mobile reciprocally toward/away from the other along an axis of movement and each provided with a work plane on which at least one curving unit is installed, suitable to curve at least a longitudinal portion of said bar, and at least a first bending unit, provided with a first contrast element having a first bending radius, and with a first bending element selectively rotatable about said first contrast element in order to bend said bar around the latter.

An irregularly-shaped diamond die is an irregularly-shaped die for producing an irregularly-shaped wire, wherein a processing hole having a bearing portion is provided, a first side and a second side that face each other are provided in a cross section of the bearing portion perpendicular to a wire drawing direction, and each of the first side and the second side has a shape that is convex toward a center side of the processing hole in the cross section.

A portable electric power tool for bending elongate objects includes an electric motor, a bender having a body portion and a bending portion which is axially moveable relative to the body portion. The bender is operatively coupled to the electric motor for causing the axial movement between a home position and a retracted position for causing force to be applied by the bender at different locations along the length of the elongate object for bending the elongate object; a home position sensor for generating output indicative that the bending portion has reached the home position during a reset stage of operation and a controller for receiving motor turn information indicative of the number of turns of the electric motor and for monitoring the axial position of the bending portion based on the motor turn information and the output generated by the home position sensor.

A cable bending system comprises at least one bending module. The bending module includes an active actuator having a first body, and an active rod mounted in the first body. The active rod is movable in a first direction perpendicular to an axial direction of a cable to be bent. A passive actuator of the bending module includes a second body connected to the first body and defines a shaping cavity open to the active rod. The active rod pushes a portion of the cable into the shaping cavity of the second body in the first direction for bending the portion of the cable.
