Abstract:
An elastically stretchable composite sheet comprising a first sheet having x- and y-directions orthogonal to each other and being elastically stretchable at least in said y-direction and a second sheet being inelastically stretchable at least in said y-direction wherein said first and second sheets are bonded intermittently in said y-direction to form the composite sheet adapted to be elastically stretchable in said y-direction, wherein:a third sheet being elastically stretchable in said y-direction and having a dimension in said y-direction longer than said first sheet is bonded to at least one surface of said first sheet intermittently in said y-direction so that said third sheet has a plurality of pleats formed due to a dimension by which said third sheet is longer than said first sheet in said y-direction; and said second sheet having a dimension in said y-direction longer than both said first and third sheets is bonded to said first directly or indirectly by means of said third sheet so that said second sheet has a plurality of pleats formed due to a dimension by which said second sheet is longer than said first sheet in said y-direction.
