Abstract

A glass substrate support system includes a first and second vacuum members extending lengthwise in a glass substrate feed direction along opposing edges of a flexible glass substrate. Each vacuum member has a vacuum body including a pressure chamber located therein and a support surface having a vacuum opening extending therethrough and in communication with the pressure chamber. A support rod assembly is provided that includes a plurality of support rods located between the first second vacuum members in the glass substrate feed direction. The support rod assembly has an out-of-plane configuration that supports the flexible glass substrate in a downward arc orientation.

First claim

What is claimed is:

1. A glass substrate support system, comprising:
first and second vacuum members extending lengthwise in a glass substrate feed direction, each vacuum member comprising a vacuum body including a pressure chamber located therein and a support surface comprising a vacuum opening extending therethrough and in communication with the respective pressure chamber; and
a support rod assembly comprising a plurality of support rods located between the first and second vacuum members and extending in the feed direction.

2. The glass support system of claim 1 , wherein the plurality of support rods comprises a first group comprising at least 5 support rods.

3. The glass support system of claim 2 , wherein each support rod of the first group is spaced equidistant from an adjacent support rod of the first group.

4. The glass support system of claim 2 , wherein the plurality of support rods comprises a second group comprising at least 5 support rods.

5. The glass support system of claim 4 , wherein the each support rod of the second group is spaced equidistant from an adjacent support rod of the second group.

6. The glass support system of claim 4 , wherein the support rod assembly comprises a planar configuration that supports the flexible glass substrate in a substantially planar orientation.

7. The glass support system of claim 6 , wherein the support rod assembly comprises an out-of-plane configuration that supports a flexible glass substrate in a downward arc orientation.

8. The glass support system of claim 7 , further comprising an actuator system that moves the support rod assembly between the planar configuration and the out-of-plane configuration.

9. A glass edge finishing apparatus comprising:
a glass substrate transport system;
a glass substrate support system moveable by the glass substrate transport system in a glass substrate feed direction, the glass substrate support system configured to support a flexible glass substrate comprising a generally planar surface and an out-of-plane direction normal to the generally planar surface, the glass substrate support system comprising:
a vacuum member extending lengthwise along an edge of the flexible glass substrate in the glass substrate feed direction, the vacuum member comprising a vacuum body including a pressure chamber located therein and a support surface comprising a vacuum opening extending therethrough and in communication with the pressure chamber; and
a support rod assembly adjacent the vacuum member and comprising a plurality of elongated support rods extending in the glass substrate feed direction, the support rod assembly comprising an out-of-plane configuration that supports the flexible glass substrate in a downward arc orientation.

10. The glass edge finishing apparatus of claim 9 , wherein the plurality of support rods comprises a first group comprising at least 5 support rods.

11. The glass edge finishing apparatus of claim 10 , wherein each support rod of the first group is spaced equidistant from an adjacent support rod of the first group.

12. The glass edge finishing apparatus of claim 9 , wherein the plurality of support rods comprises a second group comprising at least 5 support rods.

13. The glass edge finishing apparatus of claim 12 , wherein each support rod of the second group is spaced equidistant from an adjacent support rod of the second group.

14. The glass edge finishing apparatus of claim 12 , wherein the support rod assembly comprises a planar configuration that supports the flexible glass substrate in a substantially planar orientation.

15. The glass edge finishing apparatus of claim 14 , further comprising an actuator system that moves the support rod assembly between the planar configuration and the out-of-plane configuration.

16. A method of supporting a flexible glass substrate, the method comprising:
positioning a flexible glass substrate on a glass support system comprising:
first and second vacuum members extending lengthwise in a glass substrate feed direction and along opposing edges of a flexible glass substrate, each vacuum member comprising a vacuum body including a pressure chamber located therein and a support surface including a vacuum opening extending therethrough and in communication with each respective pressure chamber; and
a support rod assembly comprising a plurality of elongated support rods extending in the glass substrate feed direction and located between the first and second vacuum members; and

moving the support rod assembly from a planar configuration to an out-of-plane configuration that supports the flexible glass substrate in a downward arc orientation.

17. The method of claim 16 , wherein the step of positioning the flexible glass substrate on the glass support system comprises positioning the flexible glass substrate on the glass support system with the support rod assembly in the planar configuration.

18. The method of claim 16 , further comprising applying a positive pressure to the flexible glass substrate using the first and second vacuum members during the step of positioning the flexible glass substrate on the glass support system.

19. The method of claim 16 , further comprising, with the flexible glass substrate in the downward arc orientation, applying a negative pressure to the flexible glass substrate through the first and second vacuum members.

20. The method of claim 16 , wherein the step of moving the support rod assembly from the planar configuration to the out-of-plane configuration is performed using an actuator system.
