Abstract: In order to improve the automatic control system of digital foldout machine for prefabricated paper specification, the technology of PLC (Programmable Logic Controller) and capacitive sensor were used. The basic working principle, constitution of hardware, and design process of software were introduced in detail. The communication of human-machine interface was realized by touch screen in the system. The data were collected and converted by the high accurate capacitive sensor and its suited instruments used to measure and check. The function of prefabrication for paper specification was realized by the stepping motor which was driven by PLC. And the experimental results indicated this function was successfully realized. Additionally, the application procedure and the experimental results were given in this article.
