Abstract
Esta invencion se refiera a un aparato y a métodos para fabricar una tela compuesta teniendo un estiramiento transversal. En una modalidad un arado formador forma por lo menos una ranura en una primera tela de material. Un rodillo aplicador aplica una segunda tela de material transversalmente estirable a la primera tela mientras que se mantiene una parte frontal de la segunda tela en una relacion frontal con y separada de la primera tela formada en la ranura. Un aparato de empuje, tal como un rodillo de empuje teniendo un eje, puede empujar intermitentemente la segunda tela a adentro de la ranura y por tanto adentro de la relacion de superficie con la primera tela sobre esencialmente la totalidad de la parte frontal de la segunda tela. Las telas pueden asegurarse mediante por ejemplo un adhesivo, aplicando a partes de la primera y/o segunda tela, o mediante una union ultrasonica, para fabricar por tanto la tela compuesta. En otra modalidad, un rodillo de vacío recibe y forma por lo menos una ranura en la primera y hace avanzar la primera tela a un rodillo de punto de sujecion que asegura una superficie de referencia a la primera a la segunda tela en un punto de sujecion formado mediante el rodillo de vacío y el rodillo de sujecion mientras que se mantiene a la ranura en la primera tela. Las telas son entonces avanzadas a un aparato de empuje incluyendo un rodillo que hacer juego que coincide con el rodillo de vacío para estirar y empujar una parte fronta de la segunda hacia adentro de la ranura y hasta un aseguramiento con la primera tela para fabricar por tanto la tela compuesta. Las modalidades alternas pueden tener ranuras multiples más bien que una ranura unica.
