The current invention aims at improving the playability, durability, and spin generation of different playing rackets, as tennis, squash, and badminton rackets. The method to do so is by applying mechanical forces which generate relative motion of the latitudinal strings over the longitudinal strings. This is done in order to create friction that generate depressions in the contact points of the latitudinal strings with the longitudinal strings. These depressions, made by the described method and machine, induce more friction, and generate spin, while increasing the playability and durability during the play.

A set of racket cross-string guides which are pre-woven over a string guide holder in the same pattern used for inserting the racket cross-strings.

A device is provided for stringing a racket having a racket frame with holes in the racket frame. The device includes a frame and a cradle rotationally coupled to the frame and configured to mechanically secure the racket via the racket frame. The device also includes multiple elements coupled to at least one of the frame and cradle, including a grasping element configured to engage a string and modify the position and/or tension of the string, a clamp configured to engage the string and maintain the position and tension of the string, an imagining device, and a processor, the processor capable of receiving information from the imaging device indicative of a racket position, hole position, and/or string position, and providing instructions for operating the grasping element, clamp, and/or cradle.
