APPARATUS TO PRODUCE METAL NETS Russian patent published in 1995 - IPC

FIELD: metal nets production. SUBSTANCE: apparatus has coil holders with wires, longitudinal and transverse wires feeding mechanisms. Mechanism of longitudinal wire feeding is made as frictional drum, connected with individual drive. Apparatus has compensating section, made of loops of longitudinal wires. Frictional drum is located inside the compensating loops and transfers to longitudinal wires linear speed. Apparatus also has welding mechanism, that has welding drum with mean to catch welded part of net, made in the form of row of longitudinal grooves for laying and keeping of transverse wires in process of their welding to longitudinal wires. Welding drum is connected with individual drive, that transfer to longitudinal wires linear speed, value of which is lower, than value of linear speed, transferred by frictional drum. EFFECT: apparatus is used to produce metal nets of high quality. 2 dwg
