FLOW-ON SHEET MAKING METHOD FOR FIBER REINFORCED CEMENT BOARD

摘要

PROBLEM TO BE SOLVED: To improve dewatering efficiency of a green sheet formed of a cement slurry which is supplied on a dewatering belt and is developed, and includes cement and a reinforcing fiber as a main component; and increase in sheet making speed. SOLUTION: A water-permeable sheet (6), and an elastic roll (7) arranged on the permeability sheet and rotating in the same direction of a sheet making direction (A) are mounted to the surface side of the green sheet (3) so that floating water rising to the surface layer of the green sheet after excitation is squeezed out by the elastic roll through the permeable sheet to be discharged from the upper side of the green sheet.
