Abstract: A method of manufacturing wet wipes includes a step of continuously conveying a plurality of sheets by a conveyor, a step of folding each of the sheets toward a conveyor non-contact surface side of the sheets, a step of impregnating each of the folded sheets with the predetermined chemical solution, from a conveyor contact surface side of the sheets a step of laminating each of the sheets impregnated with the predetermined chemical solution, and a step of cutting the laminated sheets.

Abstract: This method for producing wet wipes includes the following steps: a step for vertically folding non-woven cloth sheets; a step for impregnating the sheets with a chemical; a step for stacking the sheets; a step for cutting the sheets at predetermined lengths; a step for pulling the cut sheets away from a transporting conveyer provided with a suction mechanism by means of a pusher, and stacking the cut sheets; a step for pressing a bundle comprising the sheets; and a step for packaging the bundle. The pusher is disposed between the transporting conveyers. The blades of the pusher have a plurality of tooth sections. The pusher drops the sheets suctioned to the transporting conveyer downwards by means of moving vertically downwards.

Abstract: In order to achieve both ease of removal and an increase in the rate of impregnation by a predetermined chemical, in this packaging structure of a package of wet wipes, a convex region is formed at a position containing a region that faces the opening of a main package body and that is on the upper surface of a stacked body of wet wipes. The convex region is formed protruding towards the main package body. A space is formed between the region (corresponding to the ends) aside from the convex region formed on the wet wipes and the upper surface to which the opening of the main package body is provided.

Abstract: The present invention prevents unevenness in the amount of impregnation by a predetermined chemical and prevents a decrease in ease of removal resulting from increasing the rate of impregnation by the predetermined chemical. A press device (15) has: a plurality of rollers (201, 202, 203); press belts (204a, 204b) wound around the plurality of rollers (201, 202, 203); and conveyor belts (205, 206) that convey a stacked body (800). At least one roller from among the plurality of rollers (201, 202, 203) drives the press belts (204a, 204b) at a predetermined speed of conveyance and in a predetermined direction of conveyance. The press belts (204a, 204b) are disposed with a gap in an intersecting direction (CD) perpendicular to the conveyance direction (MD) that is such that the press belts (204a, 204b) can contact both end portions (800A, 800B) of the stacked body (800) in the intersecting direction (CD).

Abstract: In a method for manufacturing wet wipes, ridge regions raised along the conveyance direction are formed in sheets by causing each of the sheets to pass through between upper folding plates and a lower folding plate and folding the sheet multiple times on itself; each of the sheets having the ridge regions formed therein is impregnated with a predetermined chemical solution; and each of the sheets having been impregnated with the predetermined chemical solution is stacked on each other. After passing through between the upper folding plates and the lower folding plate, each of the sheets makes contact at a surface thereof with a conveyance roller, the surface being located opposite an extended plane across the surface having the ridge region formed therein, the extended plane being a plane obtained by extending the surface of the lower folding plate.
