摘要

Method for breaking closed notched brittle profiles made from glass or glass-ceramic comprises crazing the required closed profiles in the brittle material, placing the brittle material on an elastic material having a Shore A hardness of 30-100, placing a sheet metal template on the non-notched side of the brittle material, applying a force on the template to break the profile and removing the material broken along the notched line from the starting material.
