Abstract

Methods and apparatuses for moving and/or transferring discrete articles are described. In particular, the methods and apparatuses relate to flexible arrangements to move and/or transfer discrete articles that vary in size and/or shape with minimal to no change in equipment.

First claim

What is claimed is:

1. A method for applying fluid pressure to a transfer member configured to transfer multiple discrete articles, the method comprising the steps of:
a. providing a transfer member comprising a transfer surface, the transfer surface comprising:
i. a first zone comprising a first plurality of fluid ports and being configured to accept a first discrete article; and
ii. a second zone at least partially surrounding the first zone, the second zone comprising a second plurality of fluid ports, wherein the first zone and the second zone collectively are configured to accept a second discrete article that is different in size and/or shape from the first discrete article;

b. applying fluid pressure only to the first plurality of fluid ports while contacting the first discrete article with the transfer surface; and
c. separately from step (b), applying fluid pressure to both the first plurality of fluid ports and the second plurality of fluid ports while contacting the second discrete article with the transfer surface;
d. wherein each of the first discrete article and the second discrete article is a disposable absorbent article or component thereof.

2. The method of claim 1 , wherein the first discrete article has a different size from the second discrete article.

3. The method of claim 1 , wherein the first discrete article has a different shape than the second discrete article.

4. The method of claim 1 , wherein the first discrete article has both a different size and a different shape than the second discrete article.

5. The method of claim 1 , wherein the transfer surface comprises (iii) a third zone proximate the second zone, the third zone comprising a third plurality of fluid ports, and wherein at least two of the first zone, the second zone, and the third zone are configured to accept a third discrete article that is different from the first discrete article and the second discrete article.

6. The method of claim 5 , wherein the third zone substantially surrounds the second zone on multiple sides thereof.

7. The method of claim 5 , wherein the third zone is disposed on only one side of the second zone.

8. The method of claim 1 , wherein the transfer surface is substantially flat.

9. The method of claim 1 , comprising rotating the transfer surface during step (b) and/or step (c).

10. The method of claim 1 , comprising translating and rotating the transfer surface during step (b) and/or step (c).

11. The method of claim 1 , comprising rotating the transfer surface about a first axis and about a second axis during step (b) and/or step (c).

12. The method of claim 1 , comprising independently supplying fluid pressure to the first plurality of fluid ports and to the second plurality of fluid ports.

13. The method of claim 1 , comprising the step of (e) orbiting the transfer member through a pick-up zone supplying a plurality of first discrete articles and a drop-off zone to deliver the plurality of first discrete articles.

14. A method for applying fluid pressure to a transfer member configured to transfer multiple discrete articles, the method comprising the steps of:
a. providing a transfer member comprising a transfer surface, the transfer surface comprising:
i. a first zone comprising a first plurality of fluid ports and being configured to accept a first discrete article; and
ii. a second zone on one side of the first zone, the second zone comprising a second plurality of fluid ports, wherein the first zone and the second zone collectively are configured to accept a second discrete article that is different in size and/or shape from the first discrete article;

b. applying fluid pressure only to the first plurality of fluid ports while contacting the first discrete article with the transfer surface; and
c. separately from step (b), applying fluid pressure to both the first plurality of fluid ports and the second plurality of fluid ports while contacting the second discrete article with the transfer surface;
d. wherein each of the first discrete article and the second discrete article is a disposable absorbent article or component thereof.

15. The method of claim 14 , wherein the first discrete article has a different size from the second discrete article.

16. The method of claim 14 , wherein the transfer surface comprises (iii) a third zone on another side of the first zone, the third zone comprising a third plurality of fluid ports, and wherein the first zone, the second zone, and the third zone are configured to accept a third discrete article that is different in size and/or shape from the first discrete article and the second discrete article.

17. The method of claim 14 , wherein the transfer surface is substantially flat.

18. The method of claim 14 , comprising rotating the transfer surface during step (b) and/or step (c).

19. The method of claim 14 , comprising translating and rotating the transfer surface during step (b) and/or step (c).

20. A method for applying fluid pressure to a transfer member configured to transfer multiple discrete articles, the method comprising the steps of:
a. providing a transfer member comprising a transfer surface, the transfer surface comprising:
i. a first zone comprising a first plurality of fluid ports and being configured to accept a first discrete article; and
ii. a second zone comprising a second plurality of fluid ports, wherein the first zone and the second zone collectively are configured to accept a second discrete article that is different in size and/or shape from the first discrete article;

b. applying fluid pressure only to the first plurality of fluid ports while contacting the first discrete article with the transfer surface; and
c. separately from step (b), applying fluid pressure to both the first plurality of fluid ports and the second plurality of fluid ports while contacting the second discrete article with the transfer surface;
d. wherein each of the first discrete article and the second discrete article is a disposable absorbent article or component thereof.
