Abstract
A method and an apparatus for compensating a radial deflection and/or a lateral deflection in tire grooving wherein a cutter movement is controlled by a plurality of operating shafts and a desired pattern grooves are formed in a tire surface, wherein the radial deflection in a direction along diameter of the tire, which is supported by a tire supporting shaft, and/or the lateral deflection in a direction along diameter of the tire are detected before or during tire grooving, an a radially driving member, which moves a cutter in a direction along diameter of the tire, and/or a laterally driving member, which moves a cutter in a direction along width of the tire, are actuated in accordance with a reference program, and concurrently a movement of the radially driving member and/or a movement of the laterally driving member are adjusted in accordance with a correction program based on the detected deflection value in order to follow the radial deflection and/or the lateral deflection. The method and apparatus forms a groove having a desired constant depth and a desired constant width at a desired constant position from the tire tread center and simplifies the structure of the program to allow a smaller size of the apparatus.
