Abstract: This system (1) for blocking one or more strings (C) of a racket on the stringing machine comprises a guide support on which two clip holders (3) each provided with a clip (37) for gripping a string (C) are mounted. Each of the clip holders (3) is movable relative to the support along a trajectory forming a closed contour around a central axis (X5) of the support.

Abstract: This system (S) for tensioning a racket string (C) comprises a traction module (1) suitable for exerting a traction force (T) on a string (C) of a racket, including a grip (3) comprising two opposite jaws (32) suitable for gripping the string (C) between them when it is tensioned, and a traction head (5) on which the grip (3) is mounted, the jaws (32) being translatable simultaneously relative to the traction head (5) and arranged such that the translation of the jaws (32) causes them to tighten around the string (C), a rail (7) on which the traction head (5) of the traction module (1) is mounted translatably, and a traction motor able to translate the traction head (5) of the traction module (1) on the rail (7), via a driving system (13).
