Abstract    Energy-saving effect of blowing-carding unit with wider carding machine was analyzed. Electric control characteristics and continuous feeding control mode based on PID were introduced. Control principles of wider carding machine were analyzed. Energy consumptions of several kinds of carding machines were contrasted. It is considered that continuous feeding can be realized by blowing-carding unit with wider carding machine，card sliver quality can be improved and electricity can be saved. ?
