Abstract
A method of applying a spacer to a glass sheet while forming an insulating glazing unit includes the step of integrating the application of the sealant to the spacer body with the automated manufacturing process. The sealant is applied to the spacer body on line so that the sealant-laden spacer body may be applied to the glass without manually handling the sealant.
Claims18
A method for forming an insulating glazing unit comprising the steps of:
- (A) providing a flexible spacer body in a storage container wherein the spacer body includes a pair of shoulders defining the width of the spacer body;
- the spacer body defining a pair of notches;
- (B) removing at least a portion of the spacer body from the storage container;
- (C) applying a first sealant to at least the notches of the spacer body to form a sealant-laden spacer body after step (B);
- (D) connecting the sealant-laden spacer body to a first glass sheet by adhesively connecting one of the shoulders to the first glass sheet after step (C) such that a portion of the first sealant engages the first sheet of glass and continuing to connect the sealant-laden spacer body to the first glass sheet to form a spacer frame;
- (E) adhesively connecting a second sheet of glass to the other shoulder of the sealant-laden spacer body after the spacer frame is formed to define an outwardly-facing channel between the two sheets of glass and the spacer body;
- and
- (F) adding a second sealant to the outwardly-facing channel after step (E).

A method for forming an insulating glazing unit comprising the steps of:
- (A) providing a flexible, desiccant-carrying spacer body in a storage container;
- the spacer body including a pair of spaced shoulders;
- (B) removing a portion of the spacer body from the storage container and feeding the spacer body into an automated apparatus adapted to apply the spacer body to a first sheet of glass;
- (C) applying a first sealant to the spacer body without fully covering the shoulders to form a sealant-laden spacer body after step (B);
- (D) forming a spacer frame directly on the first sheet of glass by attaching one of the shoulders of the sealant-laden spacer body to the first sheet of glass with an adhesive after step (C) such that a portion of the first sealant engages the first sheet of glass to form a seal between the first sheet of glass and the spacer body;
- (E) attaching a second sheet of glass to the spacer frame with adhesive such that another portion of the first sealant forms a seal between the second sheet of glass and the spacer body and defining an outwardly-facing channel between the two sheets of glass and the spacer body;
- and
- (F) adding a second sealant to the outwardly-facing channel after step (E).
