Problems solved by technology

The base member 532 is in close contact with the endless belt under the action of the vacuum suction pressure, but when a tension is applied to the base member 532 to move to the right side in the figure, there is a gap 579, each front waist region 522 arranged in the direction of mechanical movement may sometimes be misplaced or skewed on the endless belt, so sometimes the shape of the front waist region 522 may not be consistent between the various underpants 500 manufactured continuously.

Abstract

In a process for making disposable wearing article, a composite web running in a machine direction is formed with a pair of rectilinear slits extending in a cross direction and a notch intersecting these paired slits. A region surrounded by these slits and notch is cut away from the composite web to form a gap. In a step before the composite web is formed with the gap, second fastener means supported on a fastener base sheet strip are engaged with the associated pair of first fastener means previously bonded to the composite web opposed to each other about the gap as viewed in the machine direction and thereby the fastener base sheet strip is attached to the composite web so as to stride over the gap.

Description

technical field [0001] The present invention relates to a method of manufacturing a disposable wearing article having engaging components. Background technique [0002] As for the underpants type wearing article which exemplifies a disposable underpants type diaper, there is known a structure in which both side edge parts of front and back waist regions are connected by the detachable and reusable joining member. For example, WO 01 / 87209 A1 (Patent Document 1) describes a disposable training underpants 500 as shown in FIGS. 9 and 10 and a manufacturing method thereof. The underwear 500 has a first connecting member 582 on the inner surface of both side edge portions of the front waist region 522, and has a second connecting member as a mating object of the first connecting member 582 on the outer surface of both side edge portions of the rear waist region 524. 584. The first connection member 582 uses, for example, a hook-type connector, and the second connection member 58...
