Abstract (en)
[origin: WO8303358A1] In a tennis or squash racket, the strings (22, 24) are mounted without friction on the frame (12) and arranged at the surface of the frame in such a way that two parallel strands (22c, 22d) of the same string are distant by at least one ball diameter. Between said two parallel strands two other strands (24d) belonging to an other string (24) are arranged. Such arrangement of the strings allows to distribute the tension resulting from a stroke on the ball in areas which have not been in contact with the ball.
