Description

  The present invention relates to a method for manufacturing a vertically long article having a vertically long main body such as a sanitary napkin and an adhesive application portion formed on one surface side of the main body.

  Conventionally, absorbent articles such as sanitary napkins, panty liners, and incontinence pads are formed in a vertically long shape, and the absorbent article is placed on the clothing contact surface side (non-skin contact surface side) such as shorts. An adhesive part for fixing to the underwear is provided. The adhesive portion is usually covered with a sheet-like member such as a packaging material or a release sheet for individually packaging the absorbent article. When the absorbent article is used, one end in the longitudinal direction of the sheet-like member is picked with a finger. It is exposed and used by peeling along the longitudinal direction of the absorbent article.

  However, the adhesive constituting the adhesive portion has, for example, an adhesive application portion extending in the width direction orthogonal to the longitudinal direction of the absorbent article, and a plurality of the adhesive application portions with a predetermined interval in the longitudinal direction. When the sheet-like member covering the entire adhesive part is peeled along the longitudinal direction of the absorbent article as described above when applied in the arranged application pattern, the adhesive application part and the sheet form The member is intermittently peeled off, and peeling sound is generated by the intermittent peeling. In a scene where the absorbent article is used, for example, when exchanging a sanitary napkin in a toilet or a changing room, there may be a case where the sound of peeling off the napkin from shorts is heard in the surroundings and the peeling sound may be annoying.

  According to the study by the present inventors, such peeling sound can be reduced by applying the adhesive constituting the adhesive portion in a coating pattern parallel to the peeling direction of the packaging material or the release sheet. all right. That is, the adhesive has “an adhesive application portion 12 extending in the longitudinal direction L of the absorbent article 1 (a sanitary napkin in FIG. 3), and the adhesive application portion 12 has a width orthogonal to the longitudinal direction L. Applying with a plurality of application patterns (four in FIG. 3) arranged at predetermined intervals in the direction S is effective in reducing peeling sound. This application pattern is intended to prevent the above-described intermittent peeling by continuously forming the adhesive application part 12 along the peeling direction of the sheet-like member (longitudinal direction L of the napkin 1). .

  Conventionally, as described above, when an adhesive application portion extending in the longitudinal direction of an article is to be formed on the surface of the longitudinal article, as shown in FIG. In the state where the adhesive application section 12 extending in the longitudinal direction L is formed by applying the adhesive to the application means 90 and applying the adhesive with the application means 90 while maintaining the transport direction (for example, Patent Document 1). Patent Document 2 discloses a method for producing an absorbent article (sanitary napkin) employing such an adhesive application method. Specifically, a longitudinal napkin is transported in the longitudinal direction thereof. 3 and the napkin is folded in three with the transport direction maintained, and an adhesive is applied via a hot melt film to form an adhesive application pattern as shown in FIG.

  However, an adhesive application method as shown in FIG. 12, that is, an application method for applying an adhesive by supplying a longitudinal article, which is an adhesive application object, to the adhesive application means with its longitudinal direction as the transport direction, Since the longitudinal direction of the vertically long article is set as the conveying direction, the production line becomes long, and there is a problem that it takes time to manufacture the final product (the article having the adhesive application portion formed on the vertically long article).
