COMPOSITE EXTENSIBLE MEMBER AND METHOD OF MANUFACTURING THE SAME

摘要

A composite extensible member (1), comprising an extensible part (10) having two sheets of sheet materials (2) and (3) and a plurality of elastic members (4) disposed between these both sheet materials. The two sheets of sheet materials (2) and (3) are joined to each other at intermittent positions in both the extensible direction (X-direction) of the extensible part (10) and a direction (Y-direction) orthogonal to the extensible direction. The elastic members (4) are disposed in the extensible part (10) so as not to pass joined parts (5) between the both sheet materials and fixed to the both sheet materials at both ends thereof. Each of the both sheet materials (2) and (3) forms a plurality of pleats (6) continuously extending along the plurality of elastic members (4).
