Abstract:
1. A method for spraying a coating fluid on a surface of a green tire comprising the steps of: a) providing a green tire on a chuck, the green tire having a sidewall outer surface extending between a bead and a tread surface; b) providing a camera viewing the green tire on the chuck and generating from the camera an image of the green tire in profile including the tread surface and the sidewall outer surface; c) fitting a first line along a first portion of the image representing the sidewall outer surface and fitting a second line along a second portion of the image representing the tread surface; d) applying calipers to the image to determine a first reference point on the green tire where the sidewall outer surface deviates from the first line and is located a first predetermined distance from the first line and a second reference point on the green tire where the tread surface deviates from the second line and is located a second predetermined distance from the second line; and e) spraying a coating fluid on the sidewall outer surface in a circumferential area bounded by the first and second reference points, said area being less than an entire area of the sidewall outer surface.
