Study on profile measurement of extruding tyre tread by laser

摘要

This paper presents a new 2-D measuring sgstem-profile measurement of extruding tyre tread by laser. It includes the thickness measurement of extruding tyre tread by laser and the width measurement of extruding tyre tread using Moire Finge. The system has been applied to process line of extruding tyre tread. Two measuring results have been obtained. One is a standard profile picture of extruding tyre tread including Seven measuring Values. Another one is a series of thickness and width values. When the scanning speed≤100mm/sec and total width≤800mm. The measuring errors of width≤±0.5mm. While the thickness range≤40mm. The measuring errors of thickness≤±0.1mm.
