Patent ID: 8535474

Claim:
A method of producing an absorbent article having, on its side to be brought into contact with a garment, a pressure-sensitive adhesive layer formed by applying an adhesive and being adapted to be attached to the garment via the pressure-sensitive adhesive layer, the method comprising the step of applying an adhesive to a sheet material providing the side to be brought into contact with a garment by using a liquid applicator, wherein the liquid applicator comprises a discharge roller that discharges a liquid fed from feeding means in a prescribed pattern and being configured to apply the liquid discharged from the discharge roller to a moving substrate, the discharge roller comprising a surface plate as an outer peripheral portion thereof and a roller main body as a portion radially inward of the surface plate, the roller main body having in an outer peripheral portion thereof a recess of prescribed shape, in which a liquid introduced therein through inside the roller main body is adapted to spread along a surface of the surface plate, the surface plate having, in the portion thereof covering the recess, a liquid exit part that permits exit of a liquid in a pattern different from the opening shape of the recess and a liquid, block part that blocks passage of a liquid, and the liquid exit part being formed of a porous material having a large number of fine pores, wherein the liquid is an adhesive, where the fine pores of the porous material are smaller than the liquid exit part, wherein the surface plate comprises a pattern plate having a hole different in shape from the opening of the recess and a porous plate having a large number fine pores, the porous plate being superposed on the pattern plate to cover the hole, wherein the porous plate provides the outermost surface of the discharge roller, and the adhesive is applied to a sheet material thought the hole of the pattern plate and the porous plate so that the adhesive is formed in a shape of the hole of the pattern plate or the sheet material.
