Abstract

Glass web including a first glass-web portion (30), a second portion (40), and a splice joint (50) coupling the first glass-web portion to the second portion, wherein the slice joint includes a splice member (60) with at least one gas-permeable attachment portion. In further examples, methods of splicing a first glass-web portion to a second portion include the step of splicing the first glass-web portion to the second portion with a splice member, wherein the step of splicing includes attaching a gas-permeable attachment portion of the splice member to the first glass-web portion.

Claims

1. A glass web comprising:

a first glass-web portion including an end, a first major surface facing a first direction and a second major surface facing a second direction opposite the first direction;

a second portion including an end, a first major surface facing the first direction and a second major surface facing the second direction, wherein the end of the first glass-web portion and the end of the second portion are spaced apart by a gap;

a splice joint coupling the end of the first glass-web portion to the end of the second portion, wherein the splice joint comprises a first splice member including a first gas-permeable attachment portion, a second gas-permeable attachment portion, and a length extending between an outer end of the first gas-permeable attachment portion and an outer end of the second gas-permeable attachment portion, the first splice member further including a carrier layer extending between the outer end of the first gas-permeable attachment portion and the outer end of the second gas-permeable attachment portion, and an adhesive layer attached to the carrier layer;

a first part of the adhesive layer comprising a first surface of the first gas-permeable attachment portion facing the first glass-web portion and attached to the first glass-web portion with the first part of the adhesive layer disposed between the carrier layer and the first glass-web portion, and the first gas-permeable attachment portion further comprising a second surface opposite the first surface, wherein the first gas-permeable attachment portion is gas-permeable all the way through the first gas-permeable attachment portion from the first surface to the second surface of the first gas-permeable attachment portion;

a second part of the adhesive layer comprising a first surface of the second gas-permeable attachment portion facing the second portion and attached to the second portion with the second part of the adhesive layer disposed between the carrier layer and the second portion, and the second gas-permeable attachment portion further comprising a second surface opposite the first surface of the second gas-permeable attachment portion, wherein the second gas-permeable attachment portion is gas-permeable all the way through the second gas-permeable attachment portion from the first surface of the second gas-permeable attachment portion to the second surface of the second gas-permeable attachment portion;

the splice joint further comprising a second splice member including a third gas-permeable attachment portion, a fourth gas-permeable attachment portion, and a length extending between an outer end of the third gas-permeable attachment portion and an outer end of the fourth gas-permeable attachment portion, the second splice member further including a carrier layer extending between the outer end of the third gas-permeable attachment portion and the outer end of the fourth gas-permeable attachment portion, and an adhesive layer attached to the carrier layer of the second splice member;

a first part of the adhesive layer of the second splice member comprising a first surface of the third gas-permeable attachment portion facing the first glass-web portion and attached to the first glass-web portion with the first part of the adhesive layer of the second splice member disposed between the carrier layer of the second splice member and the first glass-web portion, and the third gas-permeable attachment portion further comprising a second surface opposite the first surface of the third gas-permeable attachment portion, wherein the third gas-permeable attachment portion is gas-permeable all the way through the third gas-permeable attachment portion from the first surface to the second surface of the third gas-permeable attachment portion; and

a second part of the adhesive layer of the second splice member comprising a first surface of the fourth gas-permeable attachment portion facing the second portion and attached to the second portion with the second part of the adhesive layer of the second splice member disposed between the carrier layer of the second splice member and the second portion, and the fourth gas-permeable attachment portion further comprising a second surface opposite the first surface of the fourth gas-permeable attachment portion, wherein the fourth gas-permeable attachment portion is gas-permeable all the way through the fourth gas-permeable attachment portion from the first surface of the fourth gas-permeable attachment portion to the second surface of the fourth gas-permeable attachment portion,

wherein the first gas-permeable attachment portion is attached to the first major surface of the first glass-web portion, the second gas-permeable attachment portion is attached to the second major surface of the second portion, the third gas-permeable attachment portion is attached to the second major surface of the first glass-web portion, and the fourth gas-permeable attachment portion is attached to the first major surface of the second portion.

2. The glass web of claim 1, wherein the second portion comprises a second glass-web portion.

3. The glass web of claim 1, wherein a thickness of the first glass-web portion is from about 10 microns to about 300 microns.

4. The glass web of claim 1, wherein the carrier layer of the first splice member comprises a flexible membrane.

5. The glass web of claim 1, wherein the first gas-permeable attachment portion and the second gas-permeable attachment portion each include at least one vent aperture.

6. The glass web of claim 5, wherein the at least one vent aperture of the first gas-permeable attachment portion extends all the way through the first gas-permeable attachment portion from the first surface of the first gas-permeable attachment portion to the second surface of the first gas-permeable attachment portion;

and the at least one vent aperture of the second gas-permeable attachment portion extends all the way through the second gas-permeable attachment portion from the first surface of the second gas-permeable attachment portion to the second surface of the second gas-permeable attachment portion.

7. The glass web of claim 1, wherein the adhesive layer of the first splice member extends along the entire length of the first splice member.

8. The glass web of claim 1, wherein the first gas-permeable attachment portion is made from a material that is gas permeable that at least partially provides gas permeability to the first gas-permeable attachment portion;

and the second gas-permeable attachment portion is made from a material that is gas permeable that at least partially provides gas permeability to the second gas-permeable attachment portion.

9. The glass web of claim 8, wherein the first gas-permeable attachment portion and the second gas-permeable attachment portion each include at least one vent aperture that provides further gas permeability to the first gas-permeable attachment portion and the second gas-permeable attachment portion.
