A liquid packaging machine produces liquid packaging bags by controlling a vertical seal roll, a horizontal seal roll, a cut roll cooperatively. These rolls are driven by servomotors separately as a multi-axis servo mechanism. In this paper we propose two control methods to enable the high speed production. One is two-steps velocity control of the horizontal seal roll. This method enables continuous production of bags of arbitrary size. Second is a phase control which determines the cut position on a film accurately according to the seal position. The phase control changes the rotary phase difference between the horizontal seal roll and the cut roll by adjusting the high feeding velocity of the cut roll. Experimental results using the liquid packaging machine showed the effectiveness of the proposed control methods.
