Technical parameter: Electric control install two groups of operation plate, upper and lower bridge can be adjusted arbitrarily. Characteristics: Transducer adjusts the capacity of wind, and control the tension.With PLC automatically control and keep same speed with glue machine and single facer, controls the cumuli number of paper invariableness inf favor of the volatilization of the moisture in the paperboardd and being shape.Get the signal from the detector of the mill roll stand, automatic track the edge of single corrugated paperboard to achieve the automatic adjustment.The wind plates is fully adopted chrome plating, and the easy-abrade parts is plated with tungsten carbide to make the plates' life longer.
