  • Patent number: 4662994
    Abstract: The invention proposes the use, in the manufacture of link belts, of helical coils wound from elongate synthetic plastics material of non-circular, and preferably generally rectangular, transverse cross-section, the major dimension of the said cross-section extending widthwise of the link belt.By using, for example, flat monofilament yarns of a given cross-section in the production of an oval coil of a related major dimension it is possible to increase the cross-section of the wire receiving tunnel formed by two interdigitated coils without prejudice to the capability of interdigitated coils to remain in mutual engagement, and thus facilitate the introduction of hinge wires by mechanical means.
