  • the extended recess filter is destined to the manufacturing of Papiros king cigarettes with filter.
  • said cigarette that is widely used, without the filter, in the former U.S.S.R. countries, provides a portion of the paper that is wound when empty bigger than the portion filled in with tobacco and the manufacturing of said cigarettes occurs on machines that nothing have to do with those employed to manufacture the conventional cigarettes.
  • the problems concern the capability of obtaining a sufficiently resistant structure.
  • a cigarette filter providing a first inner paper, a second intermediate paper and a third outer paper, said first and second papers having such a width that, when wound, their edge do not overlap, and the third paper having such a width that, when wound, its edges overlap; on the first inner paper, in correspondence of one of the two filter ends, a filtering element being provided.
  • said first paper is glued on said second paper
  • said second paper is glued on said third paper

Abstract

L'invention concerne un filtre (1) de cigarette comportant un premier papier intérieur (2), un second papier intermédiaire (3) et un troisième papier extérieur (4). Les premier et second papiers possèdent une largeur telle que, lorsqu'on les roule, leurs bords ne se chevauchent pas, et le troisième papier (4) possède une largeur telle que, lorsqu'on le roule, ses bords se chevauchent. On a placé un élément filtrant (5) sur le premier papier intérieur (2), en correspondance avec l'une des deux extrémités du filtre. Ainsi on forme un tube qui présente une grande portion vide ainsi qu'une consistance adéquate capable de supporter la compression, et auquel on a incorporé un élément filtrant composé d'un filtre simple, mixte, à cavités, etc..
