Abstract

"APARELHO E MéTODO PARA ESTICAR UMA PELìCULA". As películas poliméricas esticadas podem ser usadas em uma variedade de aplicações, incluindo aplicações ópticas. As condições de esticamento e formato das esteiras de esticamento, de um aparelho de esticamento, podem determinar ou influenciar as propriedades da película. Métodos e aparelhos de esticamento podem incluir regiões de esticamento ajustáveis ou definidas por zona.
