Abstract

A holding assembly for articles can be used with a flexible manufacturing system to hold an article in place. The holding assembly can be used with a printing system to print onto the article. The holding assembly can expand to fit the article. The holding assembly can include a moldable surface that can be provided with a temporarily fixed geometry through the use of a vacuum. The holding assembly can help provide a flattened outer surface for the article to facilitate printing.

First claim

What is claimed is:

1. A holding assembly configured to hold an article of footwear, comprising:
a base portion;
a last portion attached to the base portion, the last portion further comprising: a first side portion, the first side portion including an outer surface that is moldable; a second side portion; a bladder member disposed between the first side portion and the second side portion, wherein the bladder member is inflatable;
wherein the first side portion includes a frame portion, a flexible membrane and a plurality of bead members and wherein the plurality of bead members are sealed in an interior chamber bounded by the frame portion and the flexible membrane; and
wherein expanding the bladder member causes the second side portion to extend away from the first side portion.

2. The holding assembly according to claim 1 , wherein the second side portion pivots about the base portion when the bladder member expands.

3. The holding assembly according to claim 2 , wherein the first side portion remains fixed in place with respect to the base portion as the bladder member expands.

4. The holding assembly according to claim 1 , wherein the interior chamber is configured to be in fluid communication with a vacuum pump.

5. The holding assembly according to claim 4 , wherein the outer surface is substantially deformable when no vacuum is applied to the interior chamber, and wherein the outer surface is substantially rigid when a vacuum is applied to the interior chamber.

6. A holding assembly configured to hold an article of footwear, comprising:
a base portion;
a last portion attached to the base portion, the last portion including a first side portion and a second side portion, wherein the first side portion further comprises: a frame portion; a flexible membrane mounted over the frame portion;
a plurality of bead members disposed in an interior chamber formed between the frame portion and the flexible membrane;
wherein the interior chamber is configured to be in fluid communication with a vacuum pump;
wherein the first side portion has a first configuration and a second configuration, the second configuration occurring when a vacuum is applied to the interior chamber of the first side portion;
wherein the rigidity of an outer surface of the first side portion increases from the first configuration to the second configuration; and
wherein the spacing between the first side portion and the second side portion of the last portion is adjustable.

7. The holding assembly according to claim 6 , wherein the flexible membrane is pulled taut against the plurality of bead members in the second configuration and wherein the flexible membrane is loosely disposed over the plurality of bead members in the first configuration.

8. The holding assembly according to claim 6 , wherein the last portion includes a bladder member disposed between the first side portion and the second side portion.

9. The holding assembly according to claim 8 , wherein the bladder member is an adjustable pressure bladder.

10. The holding assembly according to claim 9 , wherein increasing the pressure of the bladder member acts to separate the first side portion from the second side portion and thereby increase the width of the last portion.

11. The holding assembly according to claim 6 , wherein the second side portion has a substantially rigid geometry.

12. The holding assembly according to claim 9 , wherein the pressure of the bladder member is actively increased and wherein the pressure of the interior chamber is actively decreased while the holding assembly is configured to hold the article of footwear.

13. A flexible manufacturing system for articles of footwear, comprising:
a printing system and a platform, wherein the relative position between the printing system and the platform can be changed;
a plurality of mounting arms associated with the platform;
a holding assembly including a base portion and a last portion for holding articles of footwear;
a flattening plate that can be removably attached to the plurality of mounting arms; and
wherein the flattening plate applies a force to the holding assembly when the holding assembly is disposed on the platform.

14. The flexible manufacturing system according to claim 13 , wherein the flattening plate is configured to apply a force to an article of footwear that may be disposed on the last portion of the holding assembly.

15. The flexible manufacturing system according to claim 13 , wherein the last portion includes a first side portion, a second side portion and a bladder member disposed between the first side portion and the second side portion.

16. The flexible manufacturing system according to claim 15 , wherein the bladder member can be expanded to separate the first side portion and the second side portion.

17. The flexible manufacturing system according to claim 15 , wherein the first side portion includes a moldable outer surface.

18. The flexible manufacturing system according to claim 17 , wherein the shape of the moldable outer surface can be temporarily locked in place.

19. The flexible manufacturing system according to claim 18 , wherein the flattening plate can be used to flatten portions of an article of footwear disposed between the flattening plate and the moldable outer surface of the last portion.
