The project of the present invention inhibits superabsorbent polymer exceedingly to collapse in what one side, and one side thinning absorbed thickness.The solution of the present invention,It is the method that the thickness of the absorber with liquidabsorbing fibres and superabsorbent polymer is given to thinning,System include (1) carry above-mentioned absorber processing procedure,And the processing procedure of the thickness of the above-mentioned absorber of (2) thinning,Wherein,The processing procedure of the above-mentioned absorber of the carrying,It is to keep the above-mentioned retaining surface of what by the air-breathing of the suction hole from retaining surface and by above-mentioned absorber on one side,And one side is carried out by the above-mentioned retaining surface of movement,The processing procedure of the thickness of the above-mentioned absorber of the thinning,It is to make: is configured to one side and remains opposite with the movement routine of above-mentioned retaining surface,The band member that can be moved simultaneously along above-mentioned movement routine in the preset range for bridgeing across the movement routine,In above-mentioned preset range,It is attracted by the air-breathing from above-mentioned suction hole toward above-mentioned retaining surface,And it is carried out by clamping above-mentioned absorber with above-mentioned band member with above-mentioned retaining surface.本發明之課題，在於一面抑制高吸收性聚合物過度地崩潰，並一面薄化吸收體厚度。本發明之解決手段，是將具有液體吸收性纖維及高吸收性聚合物之吸收體的厚度予以薄化的方法，係具有：(1)搬運上述吸收體的製程、以及(2)薄化上述吸收體之厚度的製程，其中，該搬運上述吸收體的製程，是一面藉由從保持面之吸氣孔的吸氣而將上述吸收體保持於上述保持面，並一面藉由移動上述保持面而進行，該薄化上述吸收體之厚度的製程，是使：被配置成一面維持與上述保持面的移動路徑相向，同時在跨及該移動路徑的預定範圍中能夠沿著上述移動路徑進行移動的帶構件，在上述預定範圍內，藉由來自上述吸氣孔的吸氣而被吸引往上述保持面，並藉由以上述保持面與上述帶構件來夾壓上述吸收體而進行。
