Method for manufacturing fiber reinforced elastic sheet, apparatus for manufacturing the same and mold to be used.

摘要

A method for manufacturing a fiber reinforced elastic sheet by extruding and processing an elastomer containing staples by 25 volume % or less. The elastomer, which uniformly flows in a sheet width direction, passes through a slight clearance (6a) of a molding dice in the vertical direction of the sheet, and then the elastomer flow is enlarged in the vertical direction of the sheet. A flow adjustment portion (7) is provided in a passage of the elastomer to flow uniformly in the sheet width direction, and a weir portion (9) is provided on the downstream side of the flow adjustment portion. A clearance Wo of an outlet in the vertical direction of the sheet, a clearance Wi formed by the weir portion in the vertical direction of the sheet and a distance l between the weir portion and the outlet have the relationship of Wo / Wi >/= 2 l >/= 3Wo 0.3 mm
