Abstract (en)
[origin: US2014034072A1] Porous masses that comprise a plurality of active particles and binder particles bound together at a plurality of sintered contact points may be useful in filters, including articles (like smoking devices) and methods relating thereto. The production of such filters may involve the production of filter rods that involves forming a desired abutting configuration that comprises a plurality of sections, the plurality of sections comprising at least one porous mass section and at least one other filter section; securing the desired abutting configuration so as to yield a segmented filter rod length; and cutting the segmented filter rod length into segmented filter rods, wherein the steps of forming, securing, and cutting are performed so as to produce the segmented filter rods at a rate of about 25 m/min or greater.
