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.
