ABSTRACT:
An expandable metal belt is formed from a plurality of figure-8 shaped sections linked together, each section being formed by weaving a tubular-shaped mesh section from spring metal wire. A coiled wire tensioned spring is passed through the center of the tubular shaped mesh and the ends of the spring are secured to the ends of the tubular mesh section. The opposite ends of the mesh section and tension spring are looped around and brought into abutting relationship and positioned in adjacent parallel relationship to the center of the mesh section to form two loops in the shape of a figure-8. The abutting ends and adjacent center of the mesh are then clamped together by bending a thin metal piece tightly around the adjacent portions of the tubular-shaped mesh section.
