Problems solved by technology

[0005] However, setting the registration mark on the target will become a constraint on the design
In addition, when the registration mark is printed on the target sheet, the printing cost increases according to the amount of ink used.
For example, if the target sheet is not printed at all, the effect of cost reduction becomes significant, but in this case, it is difficult to detect the shape of the target sheet, etc.

Embodiment Construction

[0087] Figure 1 to Figure 6 An example of a belt-type disposable diaper is shown. The symbol X in the figure represents the full width of the diaper except the connecting belt, and the symbol L represents the full length of the diaper. A hot-melt adhesive used as a bonding means for bonding components on the back side. The hot melt adhesive can be applied by slit coating, continuous line or dotted line coating, spiral, Z-shape, etc. spray coating, or pattern coating (hot melt bonding by letterpress method) Coating is carried out by a known method such as transfer of agent). At the fixing portion of the elastic member, it is possible to apply a hot-melt adhesive to the outer peripheral surface of the elastic member instead of these methods or together with these methods, and to fix the elastic member to an adjacent member. As the hot-melt adhesive, there are, for example, EVA-based, adhesive rubber-based (elastic), olefin-based, and polyester-polyamide-based adhesives, which...

Abstract

To facilitate detection of the position of a target sheet without any registration mark, the problem can be solved by a connected disposable wearable article which has a crotch part M including the center in the front-rear direction LD, a ventral-side part F extending from the center in the front-rear direction LD to the front side, and a back-side part B extending from the center in the front-rear direction LD to the rear side, has connection parts 83 which are disposed on both sides of the back-side part B and are removably attached to the outer surface of the ventral-side part F, and has, on the outer surface of the ventral-side part F, a target sheet 20 to which the connection parts 83 are connected. In the inner surface and / or the outer surface of the target sheet 20, all the corners 21 have a whiteness of 80% or more.

Description

technical field [0001] The present invention relates to a bonding defect detection method of a connecting type disposable wearing article such as a belt type disposable diaper and a target sheet in the manufacture thereof. Background technique [0002] A general connected disposable wearing article has: a crotch portion including the center in the front-rear direction; an abdominal portion extending from the center in the front-rear direction to the front; and a back portion extending from the center in the front-rear direction to the rear. Extending, at least the back side portion has wing portions protruding to the left and right sides in the width direction than the crotch portion. In addition, the wing portion has a connecting portion detachably connected to the outer surface of the abdominal portion, and the outer surface of the abdominal portion has a sheet-shaped target piece connected to the connecting portion. In use, the wing part is wound from both sides of the w...
