Abstract: This disclosure is directed to an apparatus adapted to cut an elastic member for fitness of opposite side edges around the user's legs into desired lengths and then to successively attach these lengths of the elastic member onto a disposable diaper.

Abstract: A disposable diaper includes a semi-rigid absorbent body and high flexible side flaps disposed on laterally opposite side thereof. Each of said side flaps includes a first flap disposed outside said absorbent body and a second flap diverged from said first side flap. Each of said second flaps has the associated one of an elastic band incorporated therein and turned up under an elastic effect of said associated elastic band at least along a line of the divergence.

Abstract: Here is disclosed a method for making wearable articles such as disposable diapers, disposable diaper covers or the like, more particularly, a method for formation of side flaps provided with elastic members for a desired fitness around the wearer's legs. This method comprises steps of forming a main body of the article having first side flaps extending outwards from opposite sides thereof, forming second side flaps separately of the main body, providing the second side flaps along the respective one side edges with elastic members, and joining the second side flaps along the respective other side edges and longitudinally opposite ends thereof to the top surfaces of the respective first side flaps so that the respective one side edges of the second side flaps along which the respective elastic members are disposed are directed outwards.

Abstract: Disposable absorbent underpants useful as training pants for babies, underpants for incontinents and the like, including a main body of underpants comprising a water-permeable topsheet destined to be in contact with wearer's skin, water-impermeable backsheet located on a side opposite to the topsheet and an absorbent core sandwiched between these two sheets, and elastic members adapted to form elastic gathers in a waist band and a pair of leg-holes, respectively.

Abstract: A disposable diaper is disclosed. This diaper includes an absorbent body forming a layer thicker in a crotch area than in the rest area, said thicker layer of the absorbent body defined in the crotch area pressed along both sides thereof, and elastic members located on both sides of the crotch area each made of a relatively wide material.

Abstract: A nonwoven fabrics comprising an upper layer having a substantially smooth surface and a lower layer having a density lower than that of the upper layer is provided; wherein the upper layer contains, as a principal element thereof, hydrophobic fibers, denier thereof being finer than in the lower layer, and containing a larger amount of adhesive bonding materials than in the lower layer; the lower layer contains, as a constituent fiber thereof, hydrophilic fibers and hydrophobic fibers, denier thereof being coarser than in the upper layer, and containing a smaller amount of adhesive bonding materials than in the upper layer.
