Abstract
A racket stringing machine consists of a racket cradle assembly, to lock a racket frame in place, and a tension head assembly to grip and apply tension to the string during the stringing or restringing process. During the process an electronically controlled, motor-driven assembly holds the loose end of the string and applies tension as it guides it in its motion away from the racket frame. Electronics compare at each instant the tension on the string to a previously dialed-in one and when both are equal the carriage halts.
