    • A manufacturing method for a composite sheet formed by sandwiching an absorbent body that absorbs liquid between a first sheet and a second sheet is provided. The method includes: conveying the first sheet with abutting a mold member on a surface of the mold member, the first sheet being continuous in a first direction, the mold member including a mold formed on the surface in a depressed shape and moving along the first direction perpendicular to a width direction of the surface; forming the absorbent body using a procedure in which a liquid-absorbent particle falls towards the first sheet abutting the surface and the liquid-absorbent particle is deposited on a corresponding portion of the first sheet to the mold by suction from a suction hole of the mold; and joining the second sheet and the first sheet with placing the second sheet over the first sheet, the first sheet having the absorbent body that is deposited thereon, the second sheet being continuously transported in the first direction. In the forming, a plurality of slope members having a slope is included in an up-and-down direction. A height of an upstream end of the slope and a height of a downstream end of the slope are different in the first direction. While the liquid-absorbent particle successively slides a slope of the plurality of slope members, the liquid-absorbent particle is distributed in the width direction and falls on the first sheet located on the mold member. At least one slope member of the plurality of slope members makes the liquid-absorbent particle reverse its sliding direction and slide, the liquid-absorbent particle falling from a slope member adjacent above the one slope member.
    • 提供了通过将吸收体夹在第一片和第二片之间而形成的复合片的制造方法。 该方法包括:将第一片材与模具构件的表面邻接地传送第一片材,第一片材沿第一方向连续,模具构件包括形成在凹陷形状的表面上并沿着第一片状物移动的模具 方向垂直于表面的宽度方向; 使用吸液性颗粒朝向与表面接触的第一片材​​落下的方法形成吸收体,并且吸液性颗粒通过从模具的吸入孔抽吸而在第一片材的相应部分上沉积到模具 ; 以及通过将所述第二片材放置在所述第一片材上而将所述第二片材和所述第一片材接合,所述第一片材具有沉积在其上的吸收体,所述第二片材沿着所述第一方向被连续地传送。 在成形时,具有斜率的多个倾斜构件被包括在上下方向上。 斜坡的上游端的高度和斜坡的下游端的高度在第一方向上是不同的。 当吸液性颗粒依次滑动多个倾斜部件的斜面时,吸液性粒子沿宽度方向分布,落在位于模具部件上的第一片材​​上。 多个倾斜构件中的至少一个倾斜构件使吸液性颗粒与其滑动方向相反并滑动,吸液性颗粒从斜坡构件相邻的斜坡构件下方落下。
