ABSTRACT:
A racket stringing apparatus having a racket frame clamp assembly pivotably mounted to a base. The racket frame clamp assembly includes support arms for carrying the frame clamps. The support arms are such that they allow the clamps to be self-centering with respect to the vertical axis of the base. A tension head assembly is mounted on a beam that is also connected to the base. The tension head assembly is capable of reciprocating movement along the beam. When a sufficient initial tension is placed on the strings, a portion of the tension head assembly is locked in place by a brake. The brake forces the tension head assembly to pivot and this pivoting action automatically actuates a driving means that applies and maintains a predetermined final tension on the string.
