Abstract
SE DESCRIBE UN PROCEDIMIENTO PARA ROCIAR UNA CUBIERTA TERMOPLASTICA EN EL MARGEN DE UN TUBO DE CARTON. CON ELLO, LA PIEZA PLASTIFICADA QUEDA ROCIADA EN EL ESPACIO (16) FORMADO EN LS PIEZAS INTERNA (7) Y EXTERNA (8, 8'') Y LAS PIEZAS (7,8,8'') QUEDAN ENCAJADAS ENTRE SI A PRESION. PARA PODER FABRICAR PIEZAS DE PLASTICO MAS FINAS, EN UN TIEMPO MENOR Y CON HERRAMIENTAS MAS SENCILLAS, SE PROPONE QUE EL ESPACIO PERFILADO (16) TENGA EN UN PRIMER GRADO UN GRAN VOLUMEN. MIENTRAS, LA PIEZA PLASTIFICADA LLENA CON PEQUEÑA PRESION EL ESPACIO PERFILADO, AL MENOS PARCIALMENTE (20). Y ESTE ESPACIO PERFILADO, EN UN SEGUNDO NIVEL, SE REDUCE A UN VOLUMEN MENOR QUE EL DEL ANTERIOR. CON ELLO, LA FUERZA DE PINZADO, EN LA PRESION MUTUA DE LAS PIEZAS EXTERNA (8,8'') E INTERNA (7) QUEDA ELEVADA EN EL SIGUIENTE NIVEL EN RELACION CON EL DEL PRIMER GRADO.
