| 摘要 |
The present invention refers to a method for continuous manufacturing of three- dimensional electro -welded metal nets obtained from the stacking of a plurality of flat nets, the upper one (2) of which is cut (4), folded and electro -welded directly to the underlying one (1), which is flat and horizontal, and corresponding apparatus for the manufacturing of said three-dimensional electro -welded metal nets. The apparatus that performs the folding of the upper net operates vertically from the bottom upwards, and is formed from a central strut (6), that pushes it upwards, at the midpoint between the two locator folder bars (7). The central strut (6) grips the section of the upper net (2.1) and lifts it vertically until it reaches the desired elevation, after which point the central strut (6), by pushing the longitudinal rod (5.3) upwards, folds the transverse rods (5) downwards until they reach the base net (1), where subsequently they will be further and automatically folded and electro -welded. |
