Abstract: A system and method for cleaning, protecting and lubricating hyperbolic rollers and bearings for bending, using air and oil, placed in a rotating rotor (1) that contains rollers (32) placed on bearings (34) and shafts (33) inside roller housings (30), where rollers (32) are positioned at an angle with respect to the bending axis and, as bending occurs they cause bending and also as rotor (1) rotates around the item being bent it straightens and feeds the item. Rollers (32) are placed on bearings (34) and are protected through rotational seals (35). The bearings' (34) area of rollers (32) inside the rotational seal (35) is supplied with air at pressure higher than the atmospheric, so that inflow of contaminants are inhibited, or is supplied with air enriched with oil so that bearings (34) are lubricated, and rotational seals (35) located next to bearings (34) of the rollers (32) allow the air flow from the area between the bearings towards the surrounding area.

Abstract: 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.

Abstract: 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.

Abstract: Systems and methods for producing dowel baskets from dowel side frames and transverse dowel rods. The dowel side frames are introduced at a top location of the production system, where there is initially introduced a first dowel rod and subsequently, with successive stepwise advancements, the remaining dowel rods are introduced. The dowel side frames with the dowel rods advance on guides that may rotate the dowel side frames relative to the axes of the longitudinal wires so as to impart a desired inclination angle ? relative to the rods. In following, with continuous stepwise advancements, the dowel rods are alternately welded, each to one of the opposed dowel side frames. Transverse wires are welded on the longitudinal wires to impart rigidity to the dowel basket. Subsequently, mass-produced dowel baskets may be stacked in groups.

Abstract: Systems and methods for producing metallic frames from wire or strip or other material of prismatic cross section, which material may subjected to plastic bending, and the ends of which are joined together. The production process for metallic frames occurs in three phases, in three separate positions, which may function independently of one another. In the first position the wire or strip (1) may be pulled from a spool, be straightened (2), then measured (4) in length and cut. At the second position the beginning and end of wire material (1) are there transferred, and there the ends are joined. In the third phase the frame is transferred, with its ends joined, and the measurements and bendings of the sides are made, so as to produce a desired product configuration at the third position.

Abstract: A system and method for supplying electric welding machines producing meshes (5), wherein the longitudinal wires (1) come from material wound on at least one spool (4) that is unwound with assistance of a reel (15). The longitudinal wires are fed (29), subjected to advancement (20) and straightening (17), followed by a measurement of length (7) and cutting (4) to desired length. Thus, the wires (1) are supplied to positions of sheaths 19 on an appropriate supplier arrangement (2) for longitudinal wires (1), which positions (19) correspond to locations of the longitudinal wires (1) in the mesh (5) to be produced; furthermore the longitudinal wires (1) are transferred from the supplier arrangement (2) and introduced into a suitable welding line (6) where production of mesh (5) is effected. During the production of mesh (5) the supplier (2) for longitudinal wires (1) may return to its filling position to be supplied anew with longitudinal wires (1) for the next-to-be-produced mesh (5).

Abstract: A process of production of three-dimensional products from wire (1) or other suitable material, which process may be implemented in a system (8) that may include an advancement mechanism (9), a straightening mechanism (11), a length measuring arrangement (18) towards which advances the material (1), a gripper arrangement (14) suitable to hold the material with fixed grippers (15) and simultaneously with other grippers (16) to twist it to a desired angle around its longitudinal axis (X), and a rotatable bending mechanism (12) that can bend the material plastically in one plane and simultaneously can rotate at a desired angle around the longitudinal axis (X) of the wire (1) so that it may generate bends in different planes. The system (8) implementing the process may also carry a cutting arrangement (13).

Abstract: A machine and method according to which advancing material (1) such as wire, prismatic material, or rod is gripped during the duration of its advancement from an advancement unit (2) towards a bending unit (3). The gripping is effected by a jaw (4) that grips material (1) with sufficient force so that the material (1) cannot twist. By gripping the advancing material (1), the under-production part (16) is simultaneously gripped and prevented from rotating, so that bends are made in the correct plane and the bent product is produced with great accuracy.

Abstract: According to the method, the transversal wire or rebar to be formed (1) and the longitudinal wires or rebars or other material of prismatic cross section (2), (3) are fed to the main forming and welding machine subsystem, in a stepwise manner, at the appropriate distance each time, through a driving mechanism (22-30). At this location, the transversal wire (1) is cut and then formed upon the action of a press (36). Welding of the formed transversal frame with one of the two longitudinal wires is performed while the formed transversal wire is still restrained by the action of the press (38) at the formation location. Welding with the second longitudinal wire is performed at the next production step, simultaneously with the welding of the next transversal frame with the first longitudinal wire, at the formation location. After the welding action, the transversal frame is released by the press and the forming tools (37-39), and the next production step is initiated.

All the straightening mechanisms may be driven by a common motor, through a common driving mechanism; all the bending mechanisms may be driven by a common motor, through a common driving mechanism; all the mechanisms for the changing of the bending plane may also be driven by a common motor, through a common driving mechanism; and all the cutters may be driven by a common power source. All the operation of the motors and of the driving mechanisms may be controlled and programmed by one common controlling unit.
