Abstract

"APARELHAGEM PARA A PREPARAçãO DE UM EMARANHADO FIBROSO SOPRADO EM FUSãO, PROCESSOS PARA PREPARAçãO DE UM EMARANHADO FIBROSO SOPRADO EM FUSãO, DE UM FILTRO, E DE UMA MáSCARA, EMARANHADO FIBROSO SOPRADO EM FUSãO DE MúLTIPLAS CAMADAS, E, MáSCARA". Emaranhado fibroso soprado em fusão de múltiplas camadas, bem como aparelhagem e processos de formação de emaranhados. Os emaranhados são produzidos sobre um coletor rotativo que também se move paralelamente ao seu eixo longitudinal. Os emaranhados são deste modo formados em um processo helicoidal, e o emaranhado tubular resultante é separado em uma direção paralela a um ângulo de hélice. Pela separação do emaranhado tubular em uma direção paralela ao ângulo de hélice, um emaranhado fibroso soprado em fusão de múltiplas camadas planas é proporcionado que permite a incorporação de bordas emplumadas durante a preparação do artigo.
