Abstract

La invencion se relaciona con un aparato para fabricar mitades de equipaje de lados duros y otros recipientes por formacion al vacío o formacion por presion de hojas termoplásticas (216). Se describe un aparato para formar mitades y recipientes con armazones moldeados integralmente, lo cual evita la union posterior a un armazon separado. El aparato incluye tapones de esquina (250, 250') los cuales reducen el estiramiento indeseable del material de la mitad que ocurre durante la formacion por diferencia de presion, particularmente el adelgazamiento de las porciones de esquina de la mitad. El aparato incluye formas de estirado laterales (230, 232) para utilizar más eficientemente las porciones sobrantes de la hoja termoplástica para formar el armazon moldeado integralmente. El aparato también incluye una placa de sujecion (246) para cortar el material de sobra del producto final, mientras que el artículo está en la mitad del molde (208).
