ABSTRACT:
A reverser apparatus for facilitating the cross stringing of tennis rackets to prevent the strings from frictional contact when pulling the cross strings through the longitudinally extending main strings, the apparatus comprising an in-line assembled plurality of similar members each with a string retainer, and actuator means for displacing, from an initial position in which all members are mutually aligned, every alternate member in one direction, and the members in between in an opposite direction. The members may include mating guide portions by which a member by its back side is slidably coupled to the front side of an adjacent member. The actuator means may consist of an actuator shaft bearing a plurality of eccenter cams. Between the members may be disposed spacers allowing to vary the mutual spacing of the members.
