A method including: placing at least one elastic member stretchable in the carrying direction so that at least one elastic member extends in base portions of each continuous portion located at the same positions in the carrying direction as protruding portions or in the protruding portions; and intermittently folding the divided non-woven fabrics so that the elastic member is sandwiched between the base portions and the protruding portions and so that layered portions are formed, each layered portion including a protruding portion laid on a base portion adjacent to the protruding portion.

A permanently closed containment pant includes an elastically extensible chassis and a sling positioned within the chassis. The sling is joined to the front waist region and the back waist region. The sling includes a fluid-impervious base sheet and a containment flap joined with the base sheet to create a fluid-impervious pouch. The sling also includes a first transition and a second transition that are elastically extensible in a longitudinal direction and in a transverse direction. The base sheet is a fabric laminated with polyurethane and the containment flap is a fabric laminated with polyurethane. The polyurethane surface of the base sheet is ultrasonically joined in facing relationship with the polyurethane surface of the containment flap. The permanently closed containment pant is substantially devoid of an integrated absorbent core.

A series of elastic break brakes are provided throughout a travel path of elastics in a machine operation. Elastic strands thread through each individual brake mechanism, and if an elastic strand breaks downstream, a natural snap back of the elastic, which ordinarily travels through the system under tension, drives an immediately upstream cam mechanism back, and holds the elastic thread in place at the elastic break brake immediately upstream of the break as to minimize rethreading required downstream of the elastic break brake.
摘要:
A method for producing pant-type articles having a waist-encircling portion and leg-encircling portions. The method includes forming a chassis structure and at least one elastic panel being formed by providing a first web, which is an elastic web including at least one layer of an elastic material. The first web is stretched at least 70% in at least one direction. The stretched first web is bonded while the first web is held in the stretched state to a second web. The second web includes at least one layer of an elastic or non-elastic material, and the bonded first and second webs form an elastic composite web. The elastic composite is relaxed in the at least one direction by at least 4% of the stretched length of the stretched first web. The chassis structure is assembled from chassis components including the stretched and relaxed composite web.

It is aimed to provide a device for manufacturing an elastic laminate which device can stably position an elastic member with respect to both sheets. A drive mechanism 20 includes a timing belt 25 having a guide plate 19 fixed thereto, a plurality of timing pulleys 26 configured such that the timing belt 25 is provided thereon along an annular path T including a travel path E1, a motor 28 configured to drive the timing pulleys 26 to be successively rotated in forward and reverse directions to reciprocate the guide plate 19 along the travel path E1, and a slider 29 and a rail 30 configured to permit a movement of the guide plate 19 relative to both nip rolls 5 along the travel path E1 and regulate a movement of the guide plate 19 relative to the both nip rolls 5 in a direction orthogonal to the travel path E1.
