A further object of the invention is to provide a recovering unit having the edges coated with a preparation that retains its vulcanizing properties more or less i ndefinitely so as to make practicable the application of the re-covering unit to the stripped period of time after unit has left the fact Heretofore, it has n enter of the ball for a long the prepared re-covering ory.

Still another object vide the covers in the centers with a of the invention is to propacks ready for attachment to cold rubber cement placed to the air does not on one face of each strip,

Numeral 5 refers to a center from which the former cover has been removed. The re-coverto encase the center. have been employed in securing the covers to the center, the preferred form at the present time being the use of cement. The securing of the edges The present invention proposes to apply cold cement 8 to the inner face of the covers 6 and l and on the edges 9, the term cold cement being a trade designation for a rubber cement which as has been previously stated retains its vulcanizing property notwithstanding its prolonged exposure to air. The cover pieces 6 and I will be dispensed in packs, preferably of ten or a dozen, as shown in Figure 4, congruently piled.

A mold or heating apparatus H3 is shown in Figure 3 for receiving the centers with the covers 5 and 7 in place.

As actually used, the coach or tennis attendant upon the old co-vers becoming worn, will strip the same from the balls. Two of the ready-prepared patches 6 and 7, having cold cement or other vulcanizable material along the edges 9 and The centers, place, are then placed in the heating apparatus in pressure at the surface of the ball and' result in the two pieces forming the cover being firmly in place and'the edges closely adhering together; The pieces the user complete with cold cement along the edges as well as on one face of the covers, making it feasible for the recovering of centers away from the place of manufacture. The furnishing of ready-prepared covers to individuals, coaches and attendants suitable for recovering the cen- V ters, makes .itt'onlynecessary'to have a heating apparatus in order to recover the centers, and

will result in a great savings in cost and oper ation.

Numerous variations may doubtiess be devised forming the covers come to V posure to air, one
