Abstract
A tire uniformity testing machine includes an upper spindle including an upper rim portion, a lower spindle including a lower rim portion, and a spindle actuator such as a servo actuator adapted to vary a distance between the upper and lower spindles along a y axis. The tire testing machine also includes a conveyor adapted to move an associated tire to be tested along an x axis in a conveying direction. The conveyor is driven by a conveyor actuator said as a servo actuator. A motion controller is provided and receives x axis position feedback indicating a conveying distance moved by the conveyor along said x axis and that uses the x axis position feedback to control the spindle actuator to vary the distance between the upper and lower spindles along the y axis according to a function y=F(x) for coordinated synchronous variation of the distance between the upper and lower spindles along the y axis in response to movement of the conveyor along the x axis. The conveyor also moves vertically along the y axis and its position along with y axis can also be controlled by a servo actuator for coordinated vertical movement as a function of said x axis position feedback and/or as a function of y axis position feedback provided by said spindle actuator indicating a distance between said lower and upper spindles.
