Abstract
<B> APARELHO E PROCESSO PARA FORMAçãO DE FIBRAS FUNDIDAS POR EXTRUSãO UTILIZANDO UM GáS PARA ARRASTO DAS FIBRAS <D> Aparelho e processo para produção de fibras fundidas por extrusão empregando um fluxo de ar frio primário de co-fluxo e fluxo de ar quente secundário em um bocal de fusão por extrusão. O fluxo de ar frio primário fornece a maior parte da força utilizada para atenuar a corrente de polímero em fibras, enquanto um fluxo de ar quente secundário reveste a ponta do molde e impede a saturação prematura.
