Estimating the term…
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 1/2 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.
A process for manufacturing a sheet member intended to be used as a topsheet or a backsheet forming front and rear sections of a disposable garment comprising the front section, the rear section and a crotch section extending therebetween, the crotch section having transversely opposite side edges curved inward with respect to the garment, the process for manufacturing the sheet member at least comprising the steps of:
