Abstract
A method of controlling movement of the lower chuck of a tire uniformity machine toward the upper chuck by controlling acceleration and deacceleration of the lower chuck in response to pressure encountered during its movement. One embodiment of the apparatus utilizes a low-range pressure switch connected to a pump which activates a cylinder driving the lower chuck and which senses the pressure and controls the pump in response thereto. This embodiment also employs a high-range pressure switch for sensing closing pressure. Another embodiment substitutes a linear displacement transducer and linear electrohydraulic servo actuator for the switches.
