Abstract
An apparatus for removing the rubber from the crown portion of a tire having a rotatably driven rasp and a linearly displaceable capture roller. The capture roller is moved from a load position distant the rasp to an engagement position closely adjacent the rasp. First and second tensioning rollers are biased to pinch a tire between each of the tensioning rollers and the capture roller. In forcing a captive tire into the area between the tensioning rollers, the capture roller presents to the rasp a work surface which is highly stressed. Traction-enhancement rollers further deform the tire by increasing the wrap angle around each of the tensioning rollers.
