Abstract

La presente invención se dirige a proveer un método para la formación de una lámina de polímero termoplástico con una región elástica adaptada para extenderse y contraerse en su dirección de espesor sin la preocupación de que la lámina de polímero termoplástico pueda romperse, y a la lámina fabricada mediante este método; la presente invención provee un método para la formación de una lámina de polímero termoplástico 10 a una distancia de un borde periférico externo 12 del mismo con una región elástica 11 adaptada para extenderse y contraerse en una dirección de espesor de la lámina usando un molde estacionario 5 y un molde móvil 6, cada uno teniendo una pluralidad de paletas de formación 2, caracterizado porque una pluralidad de las paletas de formación está configurada para tener perfiles en sección transversal proyectados sobre la lámina definidos por líneas curvas similares y/o líneas de flexión similares alrededor de un centro de similitud y que se extienden en la dirección de espesor de la lámina a partir del molde estacionario y del molde móvil para engancharse entre sí pero no para entrar en contacto entre sí, una etapa de introducción de la lámina entre el molde estacionario y el molde móvil y una etapa de poner las paletas de formación del molde estacionario y del molde móvil en enganche entre sí para estirar la lámina entre extremos distales de cada par de las paletas de formación adyacentes; también se provee la lámina fabricada mediante este método.
