In order to study the design method of the automatic correction system for the multilayer corrugated board production line, hardware configuration for the automatic correction system and PLC software design were put forward based on PLC, touch screen technology, light grid detection and the anti-crush roller technology. The experiment verified that the control system could automatically guide the corrugated web accurately in real time. The automatic correction system has good accuracy and quick response ability. Thus it can improve the product quality of corrugated board and will have bright prospect in corrugated industry.
