Abstract: PROBLEM TO BE SOLVED: To provide a method of taking up sheets, capable of stably taking up a large number of band-shaped sheets without generating warping and rolling collapse of individual rolls. SOLUTION: In this method of taking up sheets, sheets 30 are taken up to form roll shapes, while pressed by a press roller 44. Press load by the press roller 44 during taking up of the sheets 30 is gradually reduced from start of the taking up toward the completion, such that total load which is a total value of the press load and the weight of the taken-up sheets 30 at the time of completion of the taking up is set within a range of 80 to 110% of corresponding total load at start of the taken up.

Abstract: PROBLEM TO BE SOLVED: To prepare a surface sheet for an absorptive article having an excellent texture provided with the surface characteristics of less frictional stimulation to the skin for hardly causing skin troubles such as itch and rash even while maintaining a macro surface structure capable of quickly absorbing especially highly viscous excreta among urine (soft excrement) and blood containing stimulating materials without leaving it on a surface. SOLUTION: This surface sheet for the absorptive article having recessed and projected shapes are formed on the side of the surface to be abutted to the skin when being put on. When applying the absorptive article using the surface sheet, the recessed and projected shapes are deformed flexibly following the shape and movement of a human body and the recessed parts of the recessed and projected shapes take the highly viscous excrement thereinto and separate the highly viscous excrement from the human body.

Abstract: PROBLEM TO BE SOLVED: To provide a sheet material of which the recovery property when stretched in the flat surface direction, and the recovery property when compressed in the thickness direction are high, and which is bulky.
SOLUTION: This solid sheet material 10 is formed by laminating a first fiber layer 1 containing a fiber which is solidly curled, and a second fiber layer 2 containing a fiber being solidly curled which is the same kind with or a different kind from the first fiber. Both of the fiber layers 1 and 2 are integrated in the thickness direction by being partially bonded at numerous bonded parts 3. Numerous protruding parts 4 are formed by the protrusions of the first fiber layer 1 in spaces between respective bonded parts 3 and 3.
