Abstract

resumo “métodos para produzir filtros e hastes de filtro que compreendem massas porosas e artigos relacionados aos mesmos” trata-se de massas porosas que compreendem uma pluralidade de partículas ativas e partículas aglutinantes ligadas em uma pluralidade de pontos de contato que podem ser úteis em filtros, incluindo artigos (como dispositivos para tabagismo) e métodos relacionados aos mesmos. a produção de tais filtros pode envolver a produção de hastes de filtro que envolve formar uma configuração adjacente desejada que compreende uma pluralidade de seções, em que a pluralidade de seções compreende pelo menos uma seção de massa porosa e pelo menos uma outra seção de filtro; prender a configuração adjacente desejada de modo a produzir um comprimento de haste de filtro segmentado; e cortar o comprimento de haste de filtro segmentado em hastes de filtros segmentados, em que as etapas de formar, prender e cortar são realizadas de modo a produzir as hastes de filtros segmentados em uma taxa de cerca de 25 m/min ou maior.abstract methods for producing filters and filter rods comprising porous masses and articles related thereto concerns porous masses comprising a plurality of active particles and binder particles bonded at a plurality of contact points that may be useful in filters , including articles (such as smoking devices) and related methods. the production of such filters may involve the production of filter rods which involves forming a desired adjacent configuration comprising a plurality of sections, wherein the plurality of sections comprises at least one porous mass section and at least one further filter section; clipping the desired adjacent configuration to produce a length of segmented filter rod; and cutting the segmented filter rod length into segmented filter rods, wherein the forming, clamping, and cutting steps are performed to produce the segmented filter rods at a rate of about 25 m/min or greater.
