Abstract

resumo “filtro; método; e dispositivo para fumar” uma fieira que tem orifícios de triarco pode ser usada para produzir filamentos de triarco. em alguns casos, os orifícios de triarco têm um formato em y com três pinos e sendo que cada pino tem um arco na extremidade do pino que se afunila a partir da extremidade do arco a um ponto de conexão de um arco adjacente, e os filamentos de triarco têm uma seção transversal geralmente em formato de y com pontas bulbosas ou arqueadas. adicionalmente, os filamentos de triarco podem ser úteis em uma pluralidade de aplicações que incluem, porém sem limitação, filtros, filtros que compreendem aditivos particulados e filtros de dispositivos para fumar.
