본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 적층물을 제조하기 위한 인라인 맞물림 및 압출 적층 장치의 개략도이다.
제2도는 다이아그램 형식으로 맞물림 롤러를 나타내는 제1도의 선 2-2에서 취한 단면도이다.
제3도는 신장 전의 섬유를 나타내는 부직 섬유 웹의 단면에서 확대한 다이아그램식 스케치이다.
제4도는 웹의 양쪽 표면으로부터 외부로 연장되어나온 다수의 섬유를 제공하기 위해 증분식 신장 후 제3도의 섬유 웹을 확대한 다이아그램식 스케치이다.
제5도는 부직 섬유와 플라스틱 필름 표면 사이의 저조한 결합을 나타내기 위해 적층 후 제3도의 섬유 웹을 확대한 다이아그램식 스케치이다.
제6도는 증분식 신장에 의해 형성되고 플라스틱 필름 속으로 적충된 다수의 연장되어 나온 섬유 웹의 우수한 결합을 나타태기 위한 적층 후 제4도의 섬유 웹을 확대한 다이아그램식 스케치이다.
