Abstract
A papermaking screen device finely selects disintegrated fibers effectively to enhance a fine selection effect, and is made compact. In the papermaking screen device, fibers in an area of a papermaking raw material having a high concentration on a downstream side of a screen are disintegrated by cooperation between stirring-member one-side disintegration portions and screen other-side disintegration portions, and the disintegrated fibers are guided to an outside from a portion inside the cylindrical screen facing end-portion-side stirring members to be finely selected so as to improve the fine selection effect. Also, the papermaking screen device includes disintegration functions inside the screen so as to effectively use a height in a vertical direction of the screen, and make a whole device compact as well.
