PCT No. PCT/DE89/00273 Sec. 371 Date Oct. 30, 1990 Sec. 102(e) Date Oct. 30, 1990 PCT Filed Apr. 28, 1989 PCT Pub. No. WO89/10835 PCT Pub. Date Nov. 16, 1989.An apparatus to apply circular strips to pneumatic tires while still mounted on their wheels' rims comprising a turntable with a centered, spring supported member having a conical surface, which is slidable vertically on a shaft that rotates the turntable. The tire is horizontally disposed and frictionally engages the table while held by the centering member. The tire's sidewall is cleaned and then roughened by a chemical roughner. An application wheel supported from the turntable's framework via an adjustable bracket which includes a telescopic horizontal member is adjusted to bear directly against the sidewall at the desired location and inclination. The housing carries electrically energized heating cartridges to heat the surface to 150 degrees C., or alternatively receives a heating block for the same purpose. A preprepared strip is mounted on a spool supported adjacent the housing. A guide having interchangeable plastic inserts for specific strips is mounted adjacent the housing to feed the strip under the heated application wheel so that a strip twenty millimeters in width may be applied to an automobile tire in ninety seconds. The application wheel is pressed by a pneumatic piston and cylinder against the tire at a pressure of about three to eight bars, the tire's internal pressure being about two bars. The application wheel may have a rim or shallow teeth that prevent the tire from moving laterally while being rotated.
