PROCESS FOR MAKING ELASTICALLY STRETCHABLE COMPOSITE SHEET

摘要

In a process for making an elastically stretchable composite sheet an elastically stretchable web and inelastically stretchable web constituting together a stock web are bonded together at a plurality of bonding spots. This stock web is stretched in Y-direction and succeedingly contracted to obtain a composite sheet. The bonding spots are arranged so that each pair of the bonding spots lying adjacent to each other in Y-direction at least partially overlap each other as one of these adjacent bonding spots is translated in Y-direction. Allowing the web to contract in the first direction producing gathers evenly distributed in the first and second directions.
