ABSTRACT:
The invention relates to the formation of a tire tread profile by the application of rubber tread material upon a tire casing by employing a micro-computer programmer in conjunction with a tread material applicator apparatus. The control system employed during tread formation uses a programmer having a micro-computer unit, a floppy disk and a keyboard, interfaced with a tread material application apparatus.
In operation, the programmer is connected to a drive motor of the tire tread application assembly and operates under the control of a tire profile program stored in the floppy disk. Proper tread profile shape is arrived at as a function of the digital ratio between the actual position of the tire rotation and the transverse position of the tire tread applicator assembly. The latter is digitally controlled within the parameters of a preprogrammed set of commands, as a direct and sole function of the position of the tire casing about its spin axis.
