Research on Method for Monitoring Longitudinal Rip of Steel Cord Belt

The longitudinal ripping mechanism of steel cord belt was investigated, and the bearing force of assuasive idlers at loading place of trail was analyzed during the belt to be ripped. A new method was presented and a new practical system was developed to monitor the longitudinal ripping of steel cord belt by means of measuring the force of assuasive idlers at loading place of trail. By using strain transducers to measure the force the rip can be determined while the integral quantity of the signal exceeds the threshold value within certain time. This system possesses the advantages such as high reliability, fine real time performance, high anti jamming ability, good versatility, and convenient installation.
