METHOD OF MAKING THREE-DIMENSIONAL METAL STRUCTURES,MACHINE FOR MANUFACTURING THEM AND THREE-DIMENSIONAL STRUCTURE THEREOF

摘要

A method and apparatus for assembling three-dimensional wire structures. The method includes the steps of preparing a series of plane nettings comprising lengthwise wires and brace wires, and aligning the nettings on holders. The method further includes the steps of placing a pair of cross wires across and against the lengthwise wires of the nettings and welding the cross wires to the nettings. These last two steps are repeated, each time with the nettings in a different position, until the three-dimensional structure is completed.
