    • PURPOSE: To provide a stretchable composite sheet capable of stretching to an almost constant length in the longitudinal direction with an almost identical strength in the whole region in the lateral direction without forming many irregular shrinks and folds and a method for forming many folds on a stretchable composite sheet. CONSTITUTION: The stretchable composite sheet 1 is constituted with a non- stretchable nonwoven fabrics 2, 3 extending in the longitudinal direction and plural rows of elastic members 4 extending in the longitudinal direction and arranged with a specific space between rows in the lateral direction, and the elastic members 4 are fixed to the nonwoven fabrics 2, 3 in a stretched state. The composite sheet 1 has many folds which are formed by the repetition of alternating ups and downs in the longitudinal direction created by the nonwoven fabrics 2, 3 and the elastic members 4. The folds 5 extend in the lateral direction substantially continuously, and they are arranged in the longitudinal direction with a roughly equal space between rows.
    • 目的:提供一种拉伸复合片材,其能够在纵向方向上以几乎相同的强度在整个区域中沿长度方向拉伸至几乎恒定的长度,而不形成许多不规则的收缩和折痕以及在可拉伸的条件下形成许多褶皱的方法 复合片材 构成:伸缩性复合片1由长度方向延伸的非伸缩性无纺布2,3和沿长度方向延伸的多列弹性构件4构成,并且在横向上排列有规定间隔, 弹性部件4以拉伸状态固定在无纺布2,3上。 复合片1具有通过由无纺布2,3和弹性部件4产生的在纵向上的交替上下颠倒而形成的多个褶皱。折痕5在横向方向上大致连续延伸, 在纵向方向上布置有大致相等的行间距。
