Laser sensors

For three laser sensors are used to detect

bulges and depressions in tire production. They are mounted on a solid and

accurate transport system. Laser sensors provide single/multi track

measurement, in case of spot laser sensor or whole sidewall is scanned by

sheet-of-light laser providing tire profile in every sample instance.

monitors the signals from sensors, eliminates lettering,

performs filtering and detects bulges and dents, calculates radial and

lateral runout, performs harmonic analysis, checks tire dimensions, defect

quality clasification, according to the customer specification.
