Abstract
A tire truing machine having a carrier for supporting and moving a motor-driven cutter to and from a mounted and driven wheel having a tire with means to vary the travel of the cutter according to the desired contour of the tire, including a new and improved cutter head having means for mounting the cutter blade onto the motor drive shaft so that the distance between the cutter blade and the housing may be closely controlled to prevent dirt and rubber from entering the motor housing and further having a new and improved means for both automatic and manual sharpening of the cutter blade, and more importantly, for preventing rubber from being drawn between the carbides and the blade to prevent binding of the machine.
