Abstract: A plurality of folding units is arranged in a circumferential direction of a drum that rotates about an axis. Each of the folding units includes: a pad for holding one part of a workpiece on a pad surface; a first folding member and a second folding member each having a folding surface for folding a different part of the workpiece so as to stack the different part over the one part; and a pivot shaft arranged parallel to the pad surface. The first folding member, the second folding member, and the pivot shaft are configured to be rotated together until the folding surface reaches a facing position and a facing posture at which the folding surface faces the pad surface. The pivot shaft is configured to be displaced in a diameter direction of the drum crossing the pad surface.

Abstract: A plurality of folding units is arranged in a circumferential direction R of a drum that rotates about an axis. Each of the folding units includes: a pad for holding each workpiece while a center portion of the workpiece as viewed in a lengthwise direction is placed on the pad; and a first folding member and a second folding member arranged adjacent to both end portions of the workpiece respectively as viewed in the lengthwise direction and used for folding the workpiece so as to stack the both end portions over the center portion. The first folding member and the second folding member are arranged at the same position as the pad of each of the folding units as viewed in the circumferential direction, and a width direction of the drum parallel to the axis is defined in the lengthwise direction of the workpiece.

Abstract: The present invention provides a method of manufacturing an wearing article including: a front waist part which includes a left-front end and a right-front end; and a rear waist part which includes a left-rear end and a right-rear end forming, together with the left-front end and a right-front end, a left-side sealing portion and a right-side sealing portion. In the method, the left-side sealing portion in a layered state in which a fiber-supplemented sheet formed from a nonwoven fabric is layered on an elastic fiber sheet is formed in at least a portion of the article, the right-side sealing portion in the layered state is formed in at least a portion of the article, and, in at least a portion of the elastic fiber sheet, the fiber-supplemented sheet is not layered such that airflow is allowed to pass through the elastic fiber sheet.

Abstract: A sheet manufacturing method includes a conveying step of conveying a base material sheet; and a processing step of rotating a pair of processing rolls to sandwich a conveyance path on which the base material sheet is conveyed, wherein irregular portions along respective outer peripheral faces of the processing rolls engage with each other with a clearance to stretch the base material sheet when the base material sheet passes between the processing rolls. In the conveying step, the base material sheet is conveyed such that the base material sheet contacts along the outer peripheral face of one of the processing rolls immediately prior to passing between the processing rolls; and the tension in the conveyance direction applied to the base material sheet immediately prior to reaching the outer peripheral face of the one of the processing rolls is less than 10% of a breaking load of the base material sheet.
