ABSTRACT:
PCT No. PCT/US79/00666 Sec. 371 Date Aug. 30, 1979 Sec. 102(e) Date Aug. 30, 1979 PCT Filed Aug. 30, 1979 PCT Pub. No. WO81/00538 PCT Pub. Date Mar. 5, 1981
This invention relates to a buffing tool (10, 10a) and method for preparing internal surface portions (14) of a tire (13) for application of a sealing patch thereto. A puncture (12) formed in a beadless tire (13), having a tread formed integrally therewith, is difficult to prepare for patching by use of conventional buffing tools and methods due to the mass of tightly wrapped reinforcing wires and multiple plies incorporated in the tire. The pencil-like buffing tool (10, 10a) embodying this invention comprises a shaft (15, 15a), a buffing tip (17, 17a), and a hinge connection (18, 18a) for pivotally mounting the buffing tip (17, 17a) on the shaft (15,15a)for movement between a first, installed position aligning it with the shaft (15, 15a) and a second, operative position, for buffing the internal surface portions of the tire, responsive to rotation of the buffing tool (10, 10a).
