Glass webs and methods of splicing

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.

What is claimed is: 
     
         1 . A glass web comprising:
 a first glass-web portion including an end portion, the end portion including a first major surface facing a first direction and a second major surface facing a second direction opposite the first direction; and   a second portion including a web portion extending off the end portion of the first glass-web portion, the web portion of the second portion including a first major surface facing the first direction and a second major surface facing the second direction, the second major surface of the web portion of the second portion being free of an adhesive layer, the second portion further including a gas-permeable end portion including a carrier layer including a first major surface that is coplanar with the first major surface of the web portion of the second portion and a second major surface that is coplanar with the second major surface of the web portion of the second portion, and an adhesive layer attached to the second major surface of the carrier layer, a first part of the adhesive layer comprising a first surface of the gas-permeable end portion facing the first major surface of the end portion of the first glass-web portion and attached to the first major surface of the end portion of the first glass-web portion with the first part of the adhesive layer disposed between the second major surface of the carrier layer and the first major surface of the end portion of the first glass-web portion, wherein the gas-permeable end portion is gas-permeable all the way through the gas-permeable end portion from the first surface of the gas-permeable end portion to the first major surface of the carrier layer.   
     
     
         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 comprises a flexible membrane. 
     
     
         5 . The glass web of  claim 1 , wherein the gas-permeable end portion includes at least one vent aperture. 
     
     
         6 . The glass web of  claim 5 , wherein the at least one vent aperture extends all the way through the gas-permeable end portion from the first surface of the gas-permeable end portion to the first major surface of the carrier layer. 
     
     
         7 . The glass web of  claim 1 , wherein the gas-permeable end portion is made from a material that is gas permeable that at least partially provides gas permeability to gas-permeable end portion. 
     
     
         8 . The glass web of  claim 7 , wherein the gas-permeable end portion includes at least one vent aperture that provides further gas permeability to the gas-permeable end portion. 
     
     
         9 . The glass web of  claim 8 , wherein the at least one vent aperture extends all the way through the gas-permeable end portion from the first surface of the gas-permeable end portion to the first major surface of the carrier layer.
