METHOD OF MAKING A DISPOSABLE TRAINING PANT HAVING FUSION-SLIT SIDE SEAMS AND DISPOSABLE TRAINING PANT PRODUCED THEREFROM

摘要

A method of making and a disposable garment manufactured from a fusion-slit chas sis having a pair of seams. The seams are formed by folding the chassis in the crotch portion so that the longitudinal side regions of the front portion and rear portion are superposed to form seaming areas; each seaming area is treated with ultrason ic energy sufficient to sever the material of the seaming area in a first area while simultaneously bonding the material of the se aming area in a marginal area adjacent the first area to form a flangeless seam which extends from the disposable garment 1/16" o r less, preferably 1/32" or less, and in a preferred embodiment will form a splice between the front portion and rear porti on of the chassis. The seaming area will consist of layers of polymeric material and in a preferred embodiment will consist of nonwo ven webs of 100 % polypropylene fibers.
