Abstract
A racquet press made up of two oval shaped members, each member having an inwardly directed peripheral flange engaging the edge of the flange of the other. Each flange has at least four symmetrically arranged flat members attached to its edge remote from the other oval shaped member, a second flange is attached to the adjacent edges of the symmetrically arranged flat members and a web member connects the outer edge of these second flanges. The pin extends through each of the first mentioned flat members and a clamping device is attached to the outer end of the pins so that the pins pull the two symmetrical halves together, clamping the racquet between the flat members.
