Pull-roll cartridges for use in glass manufacturing processes and methods for making and using the same

1. A cartridge assembly for a glass web pulling roll, the cartridge assembly comprising:

a hub portion having a first end and a second end positioned opposite the first end in a cartridge axial direction;

a first retaining ring portion comprising a first snap ring and a first retaining ring member, the first retaining ring portion positioned about the hub portion proximate to the first end of the hub portion;

a second retaining ring portion comprising a second snap ring and a second retaining ring member, the second retaining ring portion positioned about the hub portion proximate to the second end of the hub portion;

a plurality of disc elements positioned between the first retaining ring portion and the second retaining ring portion and about the hub portion, wherein the plurality of disc elements has an outer diameter that is greater than an outer diameter of the first retaining ring portion and the second retaining ring portion; and

a plurality of fastening members positioned at the first end and the second end of the hub portion, the plurality of fastening members extending radially inward through respective openings in the hub portion to connect the hub portion of the cartridge assembly at opposite ends of the plurality of disc elements directly to a shaft member by engagement therewith.

2. The cartridge assembly of claim 1 , wherein at least one disc element of the plurality of disc elements comprises a plurality of spring elements arranged about the hub portion and that extend radially outward from the hub portion to an outer diameter of the at least one disc element, the plurality of spring elements biased radially outward and compliant radially inward to deflect radially inward when in contact with a glass web.

3. The cartridge assembly of claim 1 , further comprising a first biasing member positioned between the plurality of disc elements and the first retaining ring portion, wherein the first biasing member applies a compressive force to the plurality of disc elements in the cartridge axial direction.

4. The cartridge assembly of claim 3 , further comprising a second biasing member positioned between the plurality of disc elements and the second retaining ring portion, wherein the first biasing member and the second biasing member apply a compressive force to the plurality of disc elements in the cartridge axial direction.

5. The cartridge assembly of claim 4 , wherein the first biasing member and the second biasing member comprise spring washers.

6. The cartridge assembly of claim 1 , further comprising a plurality of limiters positioned between the first retaining ring portion and the second retaining ring portion, wherein the plurality of limiters has an outer diameter that is less than the outer diameter of the plurality of disc elements.

7. The cartridge assembly of claim 6 , wherein individual ones of the plurality of limiters and individual ones of the plurality of disc elements are alternately arranged on the hub portion.

8. A glass web pulling roll comprising:

a shaft member;

a cartridge assembly positioned on the shaft member, the cartridge assembly comprising:

a hub portion having a first end and a second end positioned opposite the first end in a cartridge axial direction;

a first retaining ring portion comprising a first snap ring and a first retaining ring member, the first retaining ring portion positioned about the hub portion proximate to the first end of the hub portion;

a second retaining ring portion comprising a second snap ring and a second retaining ring member, the second retaining ring portion positioned about the hub portion proximate to the second end of the hub portion;

a plurality of disc elements positioned between the first retaining ring portion and the second retaining ring portion and about the hub portion, wherein the plurality of disc elements has an outer diameter that is greater than an outer diameter of the first retaining ring portion and the second retaining ring portion; and

a plurality of fastening members positioned at the first end and the second end of the hub portion, the plurality of fastening members extending radially inward through respective openings in the hub portion to connect the hub portion of the cartridge assembly at opposite ends of the plurality of disc elements directly to a shaft member by engagement therewith.

9. The glass web pulling roll of claim 8 , wherein at least one disc element of the plurality of disc elements comprises a plurality of spring elements arranged about the hub portion and that extend radially outward from the hub portion to an outer diameter of the at least one disc element, the plurality of spring elements biased radially outward and compliant radially inward to deflect radially inward when in contact with a glass web.

10. The glass web pulling roll of claim 8 , further comprising a first biasing member positioned between the plurality of disc elements and the first retaining ring portion, wherein the first biasing member applies a compressive force to the plurality of disc elements in the cartridge axial direction.

11. The glass web pulling roll of claim 10 , further comprising a second biasing member positioned between the plurality of disc elements and the second retaining ring portion, wherein the first biasing member and the second biasing member apply a compressive force to the plurality of disc elements in the cartridge axial direction.

12. The glass web pulling roll of claim 11 , wherein the first biasing member and the second biasing member comprise spring washers.

13. The glass web pulling roll of claim 8 , further comprising a plurality of limiters positioned between the first retaining ring portion and the second retaining ring portion, wherein the plurality of limiters has an outer diameter that is less than the outer diameter of the plurality of disc elements.

14. The glass web pulling roll of claim 13 , wherein individual ones of the plurality of limiters and the individual ones of the plurality of disc elements are alternately arranged on the hub portion.
