Title
(EN) ABSORBENT ARTICLE HAVING ELASTICIZED BUMPERS AND METHOD OF MANUFACTURE
(FR) ARTICLE ABSORBANT A BOURRELETS ELASTIQUES ET SON PROCEDE DE FABRICATION
Abstract
(EN)
An absorbent article includes a moisture barrier, a bodyside liner bonded to the moisture barrier, and an absorbent structure disposed between the bodyside liner and moisture barrier. Elasticized bumpers which function as three-dimensional physical barriers to liquid movement are disposed in the margins of the article. The elasticized bumpers include an internal barrier structure and an elasticized cover disposed over the internal barrier structure and bonded to one of the margins. In particular embodiments, the elasticized cover is formed of a hydrophobic material, is unadhered to the internal barrier structure, and/or is comprised of elastic strands of variable degrees of power. A method of making the absorbent article includes the steps of providing a continuous carrier web having opposite side edges and disposing a continuous absorbent web on the continuous carrier web between the side edges. Continuous strands of an internal barrier material are disposed on the continuous carrier web with one of the strands being located between the absorbent web and each of the side edges. The continuous carrier web, absorbent web and strands of internal barrier material forming a continuous in-process composite structure which is transversely cut to form a plurality of individual, in-process composite structures. Each individual, in-process composite structure includes an absorbent structure and a pair of internal barrier structures disposed on a carrier sheet. The method also includes disposing the individual, in-process composite structures on a continuous moisture barrier web, and providing a pair of continuous covers. The continuous covers are elasticized over at least part of their length and are positioning over the internal barrier structures. The continuous covers are bonded to the moisture barrier and the moisture barrier web and the covers are cut between the individual, in-process composite structures.

Un article absorbant comprend une couche d'arrêt de l'humidité, un revêtement situé côté corps, lié à cette dernière, et un élément absorbant placé entre la couche d'arrêt de l'humidité et le revêtement situé côté corps. Des bourrelets élastiques, servant de couches physiques tridimensionnelles d'arrêt du mouvement des liquides, sont placés sur les bords de l'article. Les bourrelets élastiques comprennent une couche d'arrêt interne, et une couverture élastique placée sur cette dernière, et liée à l'un des bords de l'article. Dans certains modes de réalisation, la couverture élastique est constituée d'un matériau hydrophobe, n'adhérant pas à la couche d'arrêt interne et/ou constituée de fils élastiques ayant un degré de puissance variable. Un procédé de fabrication de cet article absorbant comprend les étapes constituant à fournir une bande de support continue, présentant des bords opposés, et à disposer une bande absorbante continue sur la bande de support continue, entre les bords latéraux. Des fils continus d'un matériau formant une couche d'arrêt interne sont placés sur la bande de support continue, un des fils étant placé entre la bande absorbante et chacun des bords latéraux. La bande de support continue, la bande absorbante, et les fils du matériau formant couche d'arrêt interne constituent une structure composite en cours de fabrication qui est coupée dans le sens transversal pour former plusieurs structures composites individuelles. Chacune de ces structures individuelles comprend une structure absorbante et une paire de structures formant couches d'arrêt internes, placées sur une feuille de support. Le procédé consiste également à disposer les structures composites individuelles sur une bande formant couche d'arrêt continue de l'humidité, et à prévoir une paire de couches de couverture continues. Ces dernières sont élastiques sur au moins une partie de leur longueur et sont positionnées sur les structures formant couches d'arrêt internes. Les couches formant couvertures continues sont liées à la couche d'arrêt de l'humidité et la bande d'arrêt de l'humidité et les couches de couverture sont coupées entre les structures composites individuelles.
