Abstract

According to certain aspects, a wrapped green body carrier for a green body includes side supports and moveable supports mounted to the side supports. Each of the moveable supports includes an inner end configured to move relative to the side supports. The green body carrier includes a flexible sheet attached to and suspended from each inner end of the moveable supports. The inner ends of the moveable supports are configured to move inward to wrap the flexible sheet around at least a portion of the green body (e.g., more than 180°). Accordingly, the wrapped green body carrier supports a large circumference of the green body and accommodates large deviations in shape and/or diameter. In certain embodiments, the flexible sheet includes radiation coupling material or radiation blocking material so that wrapping the flexible sheet around the green body improves uniformity during microwave drying.

First claim

What is claimed is:

1. A green body carrier, comprising:
at least one first side support;
at least one second side support positioned opposite the at least one first side support;
at least one first moveable support mounted to the at least one first side support, each of the at least one first moveable support comprising a first inner end configured to move relative to the at least one first side support;
a flexible sheet attached to and suspended from the first inner end of the at least one first moveable support; and
wherein the first inner end of the at least one first moveable support is configured to move inward to wrap the flexible sheet around at least a portion of a green body.

2. The green body carrier of claim 1 , further comprising:
at least one second moveable support mounted to the at least one second side support, each of the at least one second moveable support comprising a second inner end configured to move relative to the at least one second side support;
wherein the flexible sheet is attached to and suspended from the second inner end of the at least one second moveable support; and
wherein the second inner end of the at least one second moveable support is configured to move inward to wrap the flexible sheet around at least a portion of the green body.

3. The green body carrier of claim 1 , wherein the green body carrier is configured to wrap the flexible sheet around at least 180° of the green body.

4. The green body carrier of claim 1 , wherein the green body carrier is configured to wrap the flexible sheet around at least 200° of the green body.

5. The green body carrier of claim 1 , wherein the green body carrier is configured to wrap the flexible sheet around at least 300° of the green body.

6. The green body carrier of claim 1 , wherein the flexible sheet comprises at least one of radiation coupling material or radiation blocking material.

7. The green body carrier of claim 6 , wherein the radiation coupling material or the radiation blocking material is embedded within the flexible sheet.

8. The green body carrier of claim 6 , wherein the radiation coupling material or the radiation blocking material comprises radiation coupling panels or radiation blocking panels attached to an external surface of the flexible sheet.

9. The green body carrier of claim 8 , wherein the radiation coupling panels or the radiation blocking panels are positioned across a width of the flexible sheet to cover at least a portion of a circumference of the green body.

10. The green body carrier of claim 1 , wherein the first inner end of the at least one first moveable support comprises a first spool with at least a portion of the flexible sheet wrapped around the first spool.

11. The green body carrier of claim 1 ,
further comprising a first spool with at least a portion of the flexible sheet wrapped around the first spool; and
wherein the at least one first moveable support comprises a plurality of first moveable supports, each first inner end of the plurality of first moveable supports attached to a portion of the first spool.

12. The green body carrier of claim 1 , wherein the at least one first moveable support comprises a telescoping moveable support.

13. The green body carrier of claim 1 , wherein the at least one first moveable support comprises a toothed rack engaged with and driven by a pinion gear.

14. The green body carrier of claim 1 , further comprising at least one first articulation motor coupled with the at least one first moveable support and configured to move the first inner end between an extended position and a retracted position.

15. The green body carrier of claim 1 ,
further comprising at least one first spool motor coupled with a first spool having at least a portion of the flexible sheet wrapped around the first spool; and
wherein the at least one first moveable support comprises a plurality of first moveable supports, each first inner end of the plurality of first moveable supports attached to a portion of the first spool.

16. The green body carrier of claim 1 ,
further comprising a first spool with at least a portion of the flexible sheet wrapped around the first spool, and a second spool with at least a portion of the flexible sheet wrapped around the second spool;
wherein the at least one first moveable support comprises a frontward first moveable support and a rearward first moveable support, each first inner end of the frontward first moveable support and the rearward first moveable support attached to a portion of the first spool;
wherein the at least one second moveable support comprises a frontward second moveable support and a rearward second moveable support, each second inner end of the frontward second moveable support and the rearward second moveable support attached to a portion of the second spool; and
wherein the flexible sheet comprises radiation coupling material or radiation blocking material.

17. The green body carrier of claim 16 , further comprising:
at least one first articulation motor coupled with the frontward first moveable support and the rearward first moveable support, each of the at least one first articulation motor configured to move the first inner end of each of the frontward first moveable support and the rearward first moveable support between an extended position and a retracted position;
at least one second articulation motor coupled with the frontward second moveable support and the rearward second moveable support, each of the at least one second articulation motor configured to move the second inner end of each of the frontward second moveable support and the rearward second moveable support between an extended position and a retracted position;
at least one first spool motor coupled with a first spool having at least a portion of the flexible sheet wrapped around the first spool; and
at least one second spool motor coupled with a second spool having at least a portion of the flexible sheet wrapped around the second spool.

18. A method of handling a green body, comprising:
placing a green body onto a flexible sheet attached to and suspended from a first inner end of at least one first moveable support and a second inner end of at least one second moveable support, the at least one first moveable support mounted to at least one first side support and the at least one second moveable support mounted to at least one second side support; and
moving the first inner end of the at least one first moveable support relative to the at least one first side support and the second inner end of the at least one second moveable support relative to the at least one second side support inward to wrap the flexible sheet around at least a portion of the green body.

19. The method of claim 18 , further comprising rotating a first spool at the first inner end of the at least one first moveable support to adjust a length of the flexible sheet wrapped around the green body.
