UNiTED STATI-:s PATENT OFFICE REENFORCED WYIRENETTING Johan Blger, Amsterdam, Netherlands Application April 23, 1931, Serial No. 532.328, and in the Netherlands March 2, 1931 This invention relates to reenforced wire netwires of the fine netting are located above the tings as supports or insertions for plaster ceilweft wires of the stiiening wire netting. ings, walls, road coverings, and the like, and has The method of production of the reenforced ior its object to provide an efficient reenorced wire netting according to the invention is efmaterial which is cheap to manufacture. -iected as follows:

Heretofore wire nettings have been known con- A set of single heavy wires a and a set of sisting of a heavy reeniorced wire netting, complural and bundled thin wires d run in one plane bined with a liner wire netting, of which the in one longitudinal direction. Other single thin separate ne wire netting serves as a covering wires c run in the same manner but to and fro for the heavy wire netting, which, at the same in the transversal direction, weaving the middle 55 time, is arranged for suspension from the ceiling heavy longitudinal wires a between these thin beams. This combined netting, therefore, does transversal wires c and the heavy and longitudinot form an integral net-work, so that it is unnal wires al into return loops therefrom, thus suitable as a good support or insertion for a forming selvedges into the netting. The same plaster covering as it is not free from buckling, transversal thin Wires c are woven through the 70 stretching and tearing. Also, other metallic iron loops of the bundled longitudinal thin wires d. wire nettings previously known are not suitable Other single heavy wires b run in the same as plaster insertions by reason of insufcient stiffmanner in the transversal direction and are also ness. woven through the loops of the bundled longi- According to this invention, the netting contudinal thin wires d. The heavy longitudinal 75 sists of an integral unit of combined heavy rewires a, al, a2, a3 and a4 may cross the wires enforced wires with thin supporting wires. .All b in any way, as shown for example in Figs. 3, the heavy and the thin wires are interwoven 4 and 5. All crossing points e or" the heavy wires with each other and mutually in one plane and are electrically and strongly welded together.

the heavy wires are welded together at their By this method and means there is obtained 80 crossing points; consequently, the longitudinal a reenforced wire netting which forms a conwires oi the wire netting are welded into the nected stiff wire plate which does not bulge outtransversal heavy wires at all their mutual crosswardly and is statically stiff, and which can be ing points. Also, these longitudinal heavy wires bent to any desired shape by heating.
