• instruction of system
The system, by monitoring a edge of entering strip with photoelectronic sensor, will export the electronic signal of position’s change to the control amplifier, and controller will compare with preestablished guiding zero signal.
if the warp detected, the output will be a relative guiding signal to servo valve which can transform from the electronic signal into magnitude hydrolic power to drive the cylinder for pushing the recoiler, then the strip will follow up with the reciprocal direction, and align the edge of strip with the zero position of photoelectric sensor. The coiller will be dapper at the ends after the tracing process repeated. The armless constructure can install the photoelectronic sensor far from the coiller alonely.
