Process for manufacturing a sheet member forming a part of disposable garment |
摘要 |
A web intended to be used as a topsheet or a backsheet defining front and rear sections and a crotch section extending therebetween in a disposable garment is continuously fed in its longitudinal direction, and a width of the web is divided in two halves along a longitudinally extending cutting line describing a curve approximate to a sine curve in and thus two webs are obtained. These two webs are transversely spaced from each other by a predetermined dimension and one of these two webs is longitudinally shifted relatively to the other by +E,fra 1/2+EE period. Thereafter, these two webs are joined together in their overlapping regions. The two webs thus joined together is cut for every period with each pair of such overlapping regions lying in a middle of this period. The invention can thereby provide the topsheet or the backsheet without any waste pieces cut therefrom.
