- 割れ易い材料からなるシートの罫書き方法であって、
前記割れ易い材料からなるシートの第1のエッジから所定の距離だけ離れた開始点において、前記割れ易い材料からなるシートの表面に傷口を付け、
前記傷口上に電磁輻射線ビームを、前記開始点上に割り口が形成されるように照射し、
前記電磁輻射線ビームを前記シートの表面に沿って移動させて、前記割り口を前記割れ易い材料からなるシートの第2のエッジに向かって伝播させることを含み、その場合に、前記割り口は、前記電磁輻射線ビームの移動の間に前記第1のエッジと交差せず、
電磁輻射線源と前記割れ易い材料からなるシートの表面との間に配置されたマスクによって、前記開始点と前記第1のエッジとの間の前記割れ易い材料からなるシートの表面に前記電磁輻射線ビームが当るのを防止することを特徴とする、割れ易い材料からなるシートの罫書き方法。 - 前記割れ易い材料からなるシートは、ガラスまたはガラスセラミックまたはセラミックであることを特徴とする、請求項1記載の方法。
- 前記第2のエッジが前記第1のエッジとほぼ平行であることを特徴とする、請求項1または2記載の方法。
- 前記割れ易い材料が、ふくらんだ両エッジ部分を備えていることを特徴とする、請求項1記載の方法。
- 前記電磁輻射線ビームの移動が、該移動の間に前記割り口が前記割れ易い材料からなるシートの第2のエッジまで伝播しないように、前記割り口を前記第2のエッジから所定の距離だけ離れた位置にある停止点まで伝播させることを含むことを特徴とする、請求項1から4の何れか1項記載の方法。
- 前記電磁輻射線ビームをマスクすることによって、前記停止点と前記第2のエッジとの間の前記割れ易い材料からなるシートの表面に前記電磁輻射線ビームが当るのを防止することを特徴とする、請求項5記載の方法。
- 前記電磁輻射線ビームの出力を減衰させることによって、前記停止点と前記割れ易い材料からなるシートの第2のエッジとの間に前記割り口が伝播するのを防止することを特徴とする、請求項5記載の方法。
- 冷媒からなるジェットを、移動する前記電磁輻射線ビームに近接させて、前記割れ易い材料からなるシートの表面に沿って移動させることをさらに含むことを特徴とする、請求項1から7の何れか1項記載の方法。
- 前記開始点と前記第1のエッジとの間の距離が、前記電磁輻射線ビームの移動の間に前記割り口が前記第1のエッジと交差するのを防止するように選択されることを特徴とする、請求項1から8の何れか1項記載の方法。
- 前記開始点と前記第1のエッジとの間の所定の距離が少なくとも1mmであることを特徴とする、請求項1から9の何れか1項記載の方法。
- 前記マスクは、前記第1のエッジから距離d 1 だけ前記シート上に広がっており、
前記電磁輻射線ビームの移動の間に前記割り口が前記第1のエッジと交差するのを防止するように、前記開始点と前記第1のエッジとの間の所定の距離が前記距離d 1 よりも長く選択されることを特徴とする請求項1記載の方法。
