유리 웹의 분리 방법은 유리 웹 상의 경로를 적어도 하나의 레이저 빔에 노출시켜 유리 웹의 손상 없이 경로를 따라서 열 응력을 생성하는 단계 (I)을 포함한다. 이 방법은 경로가 단계 (I) 동안에 생성된 열 응력 하에 있을 동안 경로 상에 결함을 생성하고, 그 결과로 유리 웹이 결함에 응답하여 경로를 따라서 자발적으로 분리되는 것인 단계 (II)를 추가로 포함한다. Methods of separating a glass web include the step (I) of exposing a path on the glass web to at least one laser beam to produce thermal stress along the path without damaging the glass web. The methods further include the step (II) of creating a defect on the path while the path is under thermal stress produced during step (I), whereupon the glass web spontaneously separates along the path in response to the defect.
