ABSTRACT:
A tire uniformity measurement and correction apparatus capable of carrying out measurement and correction of tire uniformity efficiently without causing stagnation of a transfer line due to correction of the tire uniformity is provided.
The apparatus comprises right and left transfer conveyors arranged in two parallel files for transferring tires; rim shafts provided at each corresponding middle position of the right and left transfer conveyors for supporting and rotating the tire by upper and lower rims; a rotary drum arranged between the right and left rim shafts capable of moving in a right and left direction to be pressed against the tire supported by one of the rim shafts for detecting load condition while rotating together with the tire; grinder mechanism provided on each of the right and left transfer conveyors at a position opposite to the rotary drum with respect to the transfer conveyor; and control means for controlling uniformity measurement by the rotary drum and uniformity correction by the grinder mechanism so that when the uniformity correction of a tire supported by one of the rim shafts is carried out, the uniformity measurement of another tire supported by another rim shaft is carried out.
