    摘要: The present invention relates to an method and apparatus for springing sporting racquets to maintain differential tensions between racquet strings within the racquet, so that it is possible to provide racquets having predetermined properties of elastic quality. To maintain differential tensions between the strings, the strings are tensioned against frictional surface, with may be a high frictional surface such as a grommet strip, corner of a racquet string hole, or a pad of high friction material extending about the outer surface of the racquet.

    摘要: A method of stringing a racquet includes independently tensioning a plurality of strings in the racquet and maintaining the independent tensioning. Individual strings are held and their tensioning maintained using cleats and grommets. In this fashion, the elastic properties of the shorter strings may be matched to that of the longer strings, giving a larger sweet spot. The strings may be manufactured as a pre-woven mesh.
