Feed segments within an adjustable feed matrix may be vertically adjusted, horizontally adjusted, and adjusted for rebar thickness. The adjustable feed matrix may be used in rebar structure building. A feed column may include a plurality of feed segments. Each feed segment may include a feed input and a feed output connected by a feed cavity. The feed cavity can include a feed mechanism and/or stabilizing mechanism that allows different thicknesses of rebar to consistently pass through the feed segment to the feed output. A vertical adjustment may adjust vertical spacing of the segments and increase or decrease vertical spacing of the feed outputs, enabling different vertical spacing between rebar passing through segments of the feed column. The feed column may attach to a rail through a coupling. The coupling may be released through a horizontal adjustment, enabling the feed column to slide along the rail and adjust horizontal spacing of the feed outputs.

Systems and processes for feeding longitudinal wires in a mesh 3 production machine. Mesh 3 is produced by the welding of longitudinal wires 2 with transverse wires 6 at a welding unit 27. The longitudinal wires may be pulled from decoiler reel 40, straightened, and then deposited in longitudinals storage 19. They are then received by a longitudinals carrier 15 and transported towards welding unit 27. The longitudinal wires 2 are selectively rotated around their longitudinal axes with selected angle, and restrained until their welding with the transverse wires. This negates effects of any possible curvature acquired during their straightening with rollers 9, so that after their welding, the resulting mesh 3 is produced planar with the distortion stresses neutralized.

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.

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.
