Abstract

um método para perfuração de um filme de material plástico no qual um filme principal (1) é perfurado, enquanto é deslizado por um dispositivo de perfuração (5) por uma pluralidade de jatos de gás quente pressurizado, com uma temperatura acima da temperatura de fusão do filme principal, em que os jatos de gás quente são correlacionados com a velocidade de deslizamento do filme principal (1), e no qual faixas de reforço (25) obtidas de um filme auxiliar de material plástico (2) são conectadas ao filme principal perfurado (1), fazendo as faixas de reforço (25) aderirem entre as fileiras paralelas de furos de base (24); subsequentemente, o filme principal (1) perfurado com as faixas de reforço (25) é esticado na direção de deslizamento longitudinal. durante a perfuração, o filme principal de material plástico (1) é pressionado contra um modelo de perfuração (22), fazendo com que o filme principal de material plástico (1) penetre instantaneamente as aberturas (23) do modelo de perfuração (22) pelos referidos jatos de gás quente. um dispositivo de perfuração por gás quente (5) também é fornecido e um aparelho adequado para perfuração e alongamento de um filme de material plástico, de acordo, com o referido método.
