Abstract
Tennis racket with the racket head built up by crossing strings fastened to a frame, one set of which strings runs substantially in the longitudinal direction of the racket head and a second set of which runs substantially in the transverse direction thereof. In order to reduce the effect of unclean hits the active length of at least the longitudinal strings of a longitudinal center portion of the racket head is greater the farther away from the longitudinal center line of the racket head they are placed.
