Abstract

An absorbent article may comprise a first zone comprising graphics and a second zone comprising graphics, wherein the first and second zones have different elastic properties. Further, the absorbent article may comprise a first absorbent article component and a second absorbent article component having substantially different elastic properties, wherein the first absorbent article component comprises an elastomer. Additionally, the absorbent article may comprise a third absorbent article component overlapping the first and second absorbent article components, wherein the third absorbent article component comprises graphics on at least the portions which overlap the first and second absorbent article components.

First claim

What is claimed is:

1. A method of constructing a pull-on disposable absorbent article having a first waist region, a second waist region, and a crotch region disposed therebetween, the method comprising:
printing a first plurality of graphic objects on a first surface of a first web;
printing a second plurality of graphic objects on a second surface of a second web;
cutting a portion of the first web to form a first side panel;
cutting a portion of the first web to form a second side panel;
cutting a portion of the first web to form a third side panel;
cutting a portion of the first web to form a fourth side panel;
attaching the first side panel to the second web such that a first seam is formed;
controlling placement of the first side panel relative to an edge of the second web or the second plurality of graphics of the second web;
attaching the second side panel to the second web such that a second seam is formed;
controlling placement of the second side panel relative to an edge of the second web or the second plurality of graphics of the second web;
attaching the third side panel to the second web such that a third seam is formed;
controlling placement of the third side panel relative to an edge of the second web or the second plurality of graphics of the second web;
attaching the fourth side panel to the second web such that a fourth seam is formed;
controlling placement of the fourth side panel relative to an edge of the second web or the second plurality of graphics of the second web;
attaching the first side panel to the third side panel such that a fifth seam is formed and a first leg opening is formed; and
attaching the second side panel to the fourth side panel such that a sixth seam is formed and a second leg opening and a waist opening is formed and such that the disposable absorbent article is in a pull-on configuration.

2. The method of claim 1 , wherein the second plurality of graphics is a repeat length of graphics.

3. The method of claim 1 , wherein the controlling of the placement of the first, second, third, and fourth side panels is done via a length control system.

4. The method of claim 3 , wherein the length control system is part of a registration system that utilizes a beam vision system.

5. The method of claim 4 , wherein the beam vision system takes an image of the edge of the second web and compares it to an edge of the first side panel.

6. The method of claim 4 , wherein the beam vision system takes an image of a point of the first plurality of graphic objects and compares it to an image of a point of the second plurality of graphics.

7. The method of claim 6 , further comprising a step of taking corrective action when placing at least one of the first, second, third, and fourth side panels.

8. The method of claim 1 , wherein a registration system takes an image of at least a portion an absorbent core joined to the second web.

9. The method of claim 8 , wherein the registration system takes an image of a trailing edge of at least one of the first, second, third, and fourth side panels.

10. The method of claim 9 , wherein the registration system determines the difference between the trailing edge of at least one of the first, second, third, and fourth side panels and/or the portion of the absorbent core, and a set point.

11. The method of claim 1 , wherein a registration system compares at least a portion of the first and second plurality of graphics and at least a portion of an absorbent article component.

12. The method of claim 11 , wherein the registration system comprises a through beam radiation system.

13. The method of claim 11 , wherein the registration system comprises a combination of detection methods.

14. The method of claim 11 , wherein the registration system comprises a vision capture device adjacent a light emitting device.

15. The method of claim 11 , wherein the registration system comprises a vision capture device across from a light emitting device.

16. The method of claim 15 , wherein the vision capture device comprises a vision capture device generates a through beam image.

17. The method of claim 16 , wherein the registration system detects the location of one or more of an absorbent core, a landing zone, a topsheet, an acquisition layer, a waist feature, a leg cuff.

18. The method of claim 17 , wherein the registration system detects the location of the first plurality of graphics.

19. The method of claim 1 , wherein a registration system compares at least a portion of at least one of the first, second, third, and fourth side panels to a set point.

20. The method of claim 1 , wherein a registration system compares at least a portion of the first plurality of graphics to a set point.
