As a technical management and operator in the workshop production, you must strictly follow the requirements of the process list to lead the subject and prepare materials. Do not make mistakes.

　　Then, in the specific operation, follow the process parameters of the process list, including the number of lines and outlet depth of the rubber roller, the concentration of the operation of the rubber, the temperature of the heating section of the bakery, and the amount of wind turmoil quantum discharge volume. , The speed of booting speed, as well as the control of the tension, the tension, the control of the scroll tension, the surface temperature and composite pressure of the composite steel roller, and so on.
