초록

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.
