Abstract
A racquet having interwoven longitudinal and transverse strings, with most of the transverse strings being arranged in pairs in a pattern locating the two transverse strings of each pair in close proximity to one another, and with successive pairs being spaced apart a distance greater than the individual strings of a pair. The two strings of each pair of transverse strings are interwoven with the longitudinal strings in phase with one another, so that both of the strings of the pair are received at the same side of each longitudinal string. In conjunction with this stringing pattern, there is provided at least one elongated positioning element associated with and closely adjacent one of the pairs of transverse strings and extending therewith past a series of longitudinal strings and having locating surfaces acting to block lateral deflection of the longitudinal strings. In the preferred form of the invention, the positioning element is received between two associated transverse strings, in engagement therewith, and contains notches in which the longitudinal strings are seated and by which they are located and two elongated grooves in which the two associated transverse strings are seated and by which they are also located.
