Abstract Paper-tube machine is a machine used to coil parallelogram paper horizontally. The efficiency of old types was so low that it can not meet the need of market and they needed improvement. Variable-frequncy control and human machine interface(HMI) were applied in paper-tube machine, which performed technological modification on the old machines. The control reguirement and basic control method of the machine were introduced and the emphasis was the communication of variable frequncy speed regulation and HMI. The combination of them made additional functions, such as speed control on line, productivity calculation and easier operation. Practical application shows that the efficiency increases by 7 times and the automation of producing process has been realized．
