Abstract
A method and apparatus for removing solid tires from tubular rim bands is disclosed. A transverse cut is first made through the annular rubber tire, then the tubular rim band is heated at its inside surface to a temperature high enough to break the bond between the tire and the outer surface of the band. Also disclosed is an apparatus utilizing gas-fired infrared heat to effect the heating of the rim band.
Claims5
Apparatus for removing solid tires previously severed across their widths from circular band rims, comprising:
- a base including means for supporting the rim and tire;
- gas-fired infrared heat generating means connected to the base for heating the inside surface of the rim band around the circumference of the band;
- and
- means for effecting the circulation of flue gases associated with said infrared heat generating means in the interior space of the rim band,
- whereby, as the rim band is heated, it expands circumferentially to slip with respect to the tire, thereby breaking the bond between the rim band and the tire.
Apparatus for removing a solid tire previously severed across its width from a circular band rim by destruction of the bond between the tire and the rim, comprising a base with means for supporting the rim and tire, and a generally annular array of outwardly directed gas-fired infrared heat generators connected to the base and directed toward the inside surface of the rim band, whereby heat applied to such inside surface is conducted through the band to expand the band so that the tire is freed from the band at least in part by slippage of the tire from the expanding band.
