Abstract

PURPOSE:To make possible the tension of the strip to be controlled to a constant value, by installing the load detector, the acceleration detector, and the angle detector, in the looper arm, on purpose to find out the deviation through operations on these detected values and the settled value, and by sending the value of deviation through the D/A conversion to the driving device.
