METHOD AND DEVICE FOR MANUFACTURING COMPOSITE SHEET FOR ABSORPTIVE ARTICLE

摘要

A method of manufacturing a composite sheet for an absorptive article, the method manufacturing the composite sheet by joining in a predetermined meandering pattern a continuous body of an elastic band member to a continuous body of a sheet which is continuously conveyed in the conveyance direction. The method involves: conveying the continuous body of a sheet by winding the continuous body of a sheet around the outer peripheral surface of a conveyance roller rotating in the direction along the conveyance direction; and joining, through a rocking arm which rocks about a support shaft section in the direction intersecting the conveyance direction, the continuous body of an elastic member to a portion of the continuous body of a sheet, said portion being that which is being wound around the conveyance roller. The rocking arm is provided with a rocking end-side roller provided on the rocking end side of the rocking arm, and also with a support shaft section-side roller provided on the support shaft section side. In the joining, the continuous body of an elastic member supplied toward the support shaft section-side roller through a supply route extending in the direction of the rotation center axis of the support section is sequentially passed over both the outer peripheral surface of the support shaft section-side roller and the outer peripheral surface of the rocking end-side roller and guided to the continuous body of a sheet. The driving force for rocking the rocking arm is inputted to a position different from the position of the support shaft section of the rocking arm.
