block if the drum 148 rotates at 30 rpm or a revolution every 2 seconds 600 wires sec 1200 wires 2 sec will pass in front of the sensor 52 a sensor plot will consist of a wave of varying amplitude with the amplitude spikes representing the presence of a wire the stream of data may be analyzed and displayed to an operator by suitable display for example a computer screen may display a green light for appropriate within acceptable range wire spacing and a red light for out of acceptable range spacing the system processor may verify wire count spacing amplitude of output signal upon completion of the ply scan the portions 89 of the sidewall are brought back into an original position covering the carcass ply 92 and abutting the miniskirt 87 of the crown 86 any anomalies in the location spacing and condition of the ply wires 94 may be evaluated and a decision based upon the condition of the ply wires can be made adjustments to the assembly process or carcass components may made in u201c real time u201d as necessary to eliminate or lessen the observed and measured anomalies to ensure that the ply wires in future green tires are in an optimal anomaly free configuration and orientation the speed at which the build drum 148 rotates may be controlled for optimal scanning efficiency as set forth.
