ABSTRACT OF THE DISCLOSURE A space framework comprises two multi-wire systems of helically-wound wires, the wires which, in the one system, are wound in the one direction, and, in the other system, are wound in the other direction, being interconnected at points where they intersect. In the manufacturing process, the wires in both sys- tems are wound simultaneously in opposite directions during si- multaneous advancement. In this instance, the wires are stretched and shaped about a forming device. The wires are then intercon- nected at those points where, in the winding operation, they in- tersect at the outer contour of the space framework. A machine for manufacturing a space framework consists of magazines for supplying the wires in both systems, for winding purposes a templating and welding device for the wound wires, and an advancement means for the space framework produced at the tem- plating and welding device.
