Abstract

ELEMENTO ELÁSTICO PARA FRALDA. A presente invenção refere-se a um elemento elástico para fralda com uma camada elástica (1) e uma camada (2) de não tecido. O elemento elástico apresenta áreas de conexão (5) entre a camada elástica (1) e a camada (2) de não tecido. As áreas de conexão (5) se estendem em uma direção preferencial. A camada (2) de não tecido é ondulada quando o elemento para fralda está em estado não esticado, para garantir áreas (6) como reserva para permitir o alongamento. De acordo com a presente invenção, as áreas de conexão (5) apresentam descontinuidades (10) em sua extensão.
