Abstract
A string network for sports rackets comprises joined rectilinear string segments forming a single monolithic volume with regular openings. String networks with openings of quadrilateral, hexagonal and triangular form are shown. Being bonded and secured to each other, and having a streamlined cross-sectional area, the string segments do not move with respect to each other and stay oriented so as to minimize wind resistance during the swinging motion of the sports racket before and after ball contact. The string network is materially separated from the frame of the racquet, and means for securing the network to the frame using conventional stringing machinery are presented.
