【Abstract】 This paper deals with the controlling process of the automatic control system of sliver thickness; the funtions of individual elements of the whole system are drived. The residual unevenness of uneven waves with different wave lengths after passing through the system is calculated. It is shown that through more than one year’s production practice in Shanghai Cotton Mill No.7 the evenness wave of the sliver length over 5 meters having become much better, the quality of sliver has been improved.更多还原
