Abstract: The filter rod making machine ZL26 was introduced, including, the scheme, technical process, control, configuration of Siemens MC AC servo system and technological design of master and slave motors.The practical production data showed that:by using AC servo system, the variation coefficient of filter rod weight reached 1%, the yield of filter rod was increased;the variance of draw resistance of filter rod was controlled in the rang of ±147Pa, which was much better while comparing with the products made by the filter rod maker whose opening rollers were driven through stepless gears;the hardness of filter rod met demands, and the consumption of plasticizer was reduced.
