ABSTRACT:
An elongate elastomeric tread strip having a contoured tread face of at least two ribs and an intervening valley is applied to a peripheral tread supporting surface of a pneumatic tire carcass by laying the flat back of one end portion of at least one such strip against and generally tangent to the tread supporting surface of the carcass, and rotating the carcass to wrap the tread strip therearound while stitching the strip to the carcass by pressingly engaging the contoured face of the tread strip with a contoured roller defining a moving contoured surface whose contour at least substantially matches that of the tread strip. The method and apparatus also provide for subjecting the tread strip to a rapidly vibrating force to aid further in causing the strip to uniformly contact the tire carcass throughout the width of the tread strip being applied to the carcass.
