  • Patent number: 8597458
    Abstract: A manufacturing method for a composite sheet which includes: conveying a first continuous sheet in a first direction so as to abut a depressed surface of a mold member; forming an absorbent body by depositing liquid-absorbent particles on a portion of the first sheet proximal to a suction hole of the mold; and joining a second sheet over the first sheet having the absorbent body that is deposited therebetween, the second sheet being continuously transported in the first direction. A plurality of opposed slope members guide the liquid-absorbent particles onto the first sheet located on the mold member. At least one of the plurality of slope members causes the liquid-absorbent particles to reverse their falling direction from an upper slope member.

  • Publication number: 20130291324
    Abstract: In a wet sheet, hydrophobic outer layer sheets are disposed on both sides of the hydrophilic inner layer sheet impregnated with cleaning solution. Each of intermediate layer sheets is folded over so as to form a space having an opening. End portions of the inner layer sheet are inserted into the spaces of the intermediate layer sheets. The inner layer sheet can come in contact with the outer layer sheet via a space between the intermediate layer sheets. With such a construction, sufficiently high frictional force acts between the inner layer sheet and the outer layer sheet.
