ABSTRACT:
Racket stringing equipment having movable arms, for holding the racket on the stringing cradle as the racket is strung, includes profiled gripping jaws to bring the string mesh plane of the racket into alignment with a predefined stringing plane. The string tensioner holds the string being applied to the racket in a raised position in alignment with the reference stringing plane, as the racket is being strung. The string tensioner moves to a retracted position as the stringing cradle is rotated, to allow the handle of the racket to pass over the string tensioner, and returns to the raised position when the racket handle has passed. The clips for holding tension in the strings strung on the racket are freely rotatably mounted on a rotatable satellite arm. An electromagnetic lock simultaneously locks the satellite arm and the mounting arm of the clip to prevent movement of the clip with respect to the stringing cradle.
