ABSTRACT:
Apparatus for clamping one string of a three or more direction oriented string network of a game racket held in a support fixture, to that support fixture. The apparatus includes a pair of jaws adapted to be selectively biased against the string-to-be-clamped in the string network. The jaws include a portion adapted for extension through the openings between the strings of the network, including a plurality of teeth defined by inter-tooth grooves having angular orientations and spacings matching the angular orientations and spacings of the strings crossing the string-to-be-clamped in the network. In another form, an apparatus for selectively clamping two adjacent parallel strings of a three or more direction oriented string network in a game racket includes two pairs of jaws adapted for clamping the two strings. The jaws include a portion adapted for extension through the openings between the strings in the network, including a plurality of teeth defined by inter-tooth grooves having angular orientations and spacings matching the angular orientations and spacings of the strings crossing the two strings-to-be-clamped in the string network.
