ABSTRACT:
The lengths of string (22 and 24) of a racket, more specifically a tennis or squash racket, are trained over bend points of the frame (12) with a low degree of friction and are so strung backwards and forwards across the frame that the spacing between two parallel strings of the same length of string (22) is at least equal to the radius of a ball. Between these strings (22c and 22d) there are parallel strings (24d), that are parts of other string lengths (24). This system of stringing the frame makes it possible for tension forces produced on ball impact to be transmitted to other parts of the array of strings not contacting the ball.
