Abstract

Un método y un aparato para envolver una serie almas absorbentes con una capa permeable al fluido incluye un primer mecanismo de suministro para proporcionar una primera capa de material permeable al fluido, y un mecanismo de depósito para colocar una serie de almas absorbentes sobre la primera capa. Cada una de las almas absorbentes define una periferia de las mismas e incluye un material superabsorbente ahí. Unos segundos medios de suministro de tela proporcionan una segunda capa de el material permeable al fluido para tener en forma de emparedado las almas absorbentes entre las capas primera y segunda. Un mecanismo de sellamiento asegura la primera capa y la segunda capa a lo largo de una región de sujeción de las mismas la cual está localizada a un lado de por lo menos un par de las regiones de borde laterales de las almas absorbentes. La región de sujeción está construida para evitar substancialmente el movimiento de el material superabsorbente desde las almas absorbentes a través de la región de sujeción. Un mecanismo separador remueve regiones seleccionadas de las capas primera y segunda las cuales están localizadas a un lado de la región de sujeción y están espaciadas de las almas absorbentes.
