Dewatering element
In wire section the fibers form the paper sheet. But this paper sheet is very wet. To get final dry paper, we need to remove the water from the paper sheets. So dewatering element is the first stage to suction waters from forming wire and paper sheet. In this coating cardboard making machine, we select super quality dewatering elements and the numbers of the suction box are carefully calculated.
