Abstract
A racquet stringing machine includes a base, a racquet mounting frame attached to the base for mounting and securing a racquet to be strung with string, a string clamping device which holds the clamped end of the string in place relative to the racquet frame while tension is being applied to the tensioning end of the string and a string tensioner having a string tensioner frame mounted to the base in offset relation to the racquet mounting frame, a tension setting mechanism movably mounted to the string tensioner frame for applying a desired amount of tension to the strings and a string gripper mounted to the tension setting mechanism for holding the tensioning end of the string while tension is applied. The racquet stringing machine is improved by providing a rotational string guide mounted in a fixed relation to the string gripper which guides the tensioning end of the string into the string gripper such that the line of action of the force from the string being tensioned against the string gripper remains the same regardless of the elevation of the clamped end of the string relative to the string gripper. In addition, the tension in the string on the string tensioner side of the string guide is the same as the string tension in the string on the string clamp side of the string guide.
