Abstract

"EXTRUSãO A ALTA VELOCIDADE PARA FECHAMENTO DE SACOS" Apresenta-se um processo para a extrusão a alta velocidade de elementos perfilados (16) para unidades de armazenamento doméstico, como sacos termoplásticos reutilizáveis. Elementos de travamento entre si ou tiras de zíper de plástico são extrudadas diretamente em um banho de água (17) para serem resfriadas bruscamente, e são estiradas através do banho (17) por uma distância suficiente para resfriar os elementos (16) abaixo do ponto de amolecimento do material extrudado. Taxas de coleta de cerca de 61 a cerca de 107 metros lineares por minuto (200 a 350 pés lineares por minuto) são atingidas pela passagem dos elementos através de uma profundidade de pelo menos 0,9 metros (3 pés) de água antes de seu primeiro contato com um elemento de manipulação sólido (19).
