    A filter for a cigarette includes a porous filter rod circumscribed by a smoke impervious wrapper wherein the filter rod with the smoke impervious wrapper therearound is provided with grooves embedded therein and extending from one end thereof a preselected distance longitudinally therealong. Tipping material circumscribes the smoke impervious wrapper and is provided with flow-through openings therein in flow communication with the grooves. Support means are provided for the tipping material at the mouth end of the filter to maintain the tipping material in circumferential equalization.

    one ,
    This invention relates to the tobacco industry and can be used in the manufacture of cigarettes.
    The aim of the invention is to increase the stiffness of the filter on its peripheral surface.
    Fig. 1 shows a filter for cigarettes with a support ring attached to the outer surface of the filter; in fig. 2 - filter with a support ring located between the cover and the paper; in FIG. 3, a filter with grooves filled with a filter | per material.
    Filter for cigarettes includes a cylindrical filter rod 1 of porous material enclosed in a smoke-tight: wrapped 2. placed longitudinally along rod 1 from one end to the other and wired at the oral end of the filter at least one longitudinal at one end of the groove 3, the length of which is less than the length of the filter rod 1, the strip 4 of breathable paper extending in the longitudinal direction from the wrapper 2 and surrounding it.
    The filter is equipped with supporting means 5, placed on the oral end of the filter.
    The rod 1 is made of a fibrous or foamy porous material from a standard cellulose acetate rod or similar material, wrapped with non-porous smoke-permeable material to form a wrapper 2 and, by means of, for example, heat-forming form longitudinal grooves 3.
    The breathable paper strip 4 is provided with two parallel rows of ventilation perforations 6, which are located above the longitudinal grooves 3.
    12
    The strip 4 of breathable paper is attached to the tobacco rod 7.
    The support means 5 can be made in the form of a ring of an airtight or air-permeable flexible material, for example plastic.
    The strip 4 of breathable paper is usually thin and flexible. In order to maintain the external shape of the filter during use, support means 5, made in the form of a ring, are placed on the oral end
    filter can be attached to the outer surface of the paper strip 4 (Fig. 1) or can be located between the strip 4 and the wrapper 2 and attached to them both
    (Fig. 2).
    It is possible to perform the support means 5 as follows (FIG. 3).
    The longitudinal grooves 3 fill
    a porous filtering material, for example, similar to the material from which rod 1 is made. The material is chosen in such a way that a large drop in pressure of the passing air is not created.
    Embodiments of the filter (Fig. 2 and 3) provide for the location of the means 5 under the strip 4,
    When using fsttra support
    the means 5 ensure the preservation of the filter during the passage of air through the perforated strip 4 of breathable paper along the longitudinal ganawack 3 through the oral end of the filter
    ra in a smoker's mouth.
    The invention provides an increase in the stiffness of the filter on its peripheral surface by strengthening the oral end of the filter with supporting means,
