Embodiment 1

[0024] as attached figure 1 The grooved feeding filter rod shown is formed by wrapping a layer of embossed grooved cellulose paper 2 on the periphery of the cellulose acetate filter element 1, and then wrapping high-transparency forming paper 3 on the periphery of the grooved cellulose paper 2. The surface of the grooved cellulose paper 2 has a combination of grooved segment 4 and flat segment 6, and the filter element 1 wrapped in the grooved segment 4 contains solid granular activated carbon additive 5 for adsorption, filtration or flavoring.

Embodiment 2

[0026] as attached figure 2 The smoke filter tip made of the grooved feeding filter rod shown is cut into the grooved feeding subsection 7 by the grooved feeding filter rod in the embodiment 1, and then the common grooved filter rod is selected and cut into other subsections 8, The two kinds of small sections are spliced ​​together, and finally coated with a layer of outer ring forming paper 9 to form a compound. Wherein, when the cigarette filter is installed on the cigarette, near the shredded tobacco end 10 is a groove feeding segment 7, and the surface of the grooved cellulose paper 2 in the segment has a groove segment 4; near the lip tooth end 11 is other segments 8.

[0027] The smoke filter made of the grooved filter rod not only has the good smoke permeability of the grooved filter rod, and all the tows of the filter element play a role; Effective and full use, the adsorption, filtration or flavoring functions of the cigarette filter are better.

Abstract

The invention provides a groove feeding filter stick is characterized by being formed through firstly coating a layer of groove cellulose paper at the periphery of a filter core and then wrapping a layer of forming paper. The surface of the groove cellulose paper is formed by a through long groove section or combination of a groove section and a flat section, the filter core coated at the groove section contains adsorptive, filtering or flavored additive. The filter tip made by the groove feeding filter stick is formed by splicing a groove feeding small section and other small sections and finally coating an outer ring forming paper for compounding, and the lip close end of a cigarette is of other sections. The filter stick and the filter tip are novel and unique in structure, have the advantages of adsorbing, filtering or flavoring the feeding filter stick, and the advantages of good smoke ventilation, filter core strands and fully-played additive of the groove filter stick.

Description

technical field [0001] The invention relates to a filter stick material for manufacturing cigarette filter tips and the finished product of the cigarette filter tips. Background technique [0002] Cigarette filter is the filter material of cigarettes. The structure and filtering effect of cigarette filter have a significant impact on the variety and quality of cigarettes. Commonly used filter rods (or cigarette filters) are composed of filter elements and forming paper. High-grade filter rods (or cigarette filters) have a ring of cellulose paper with grooves on the periphery of the filter element and inside the forming paper, and some filter rods (or cigarette filters) contain special additives in the filter element. [0003] The applicant's application number is CN201010241592.8 patent specification discloses a "filter rod containing tobacco particles and its preparation method". In the rod tow, a filter rod forming machine is used to prepare a filter rod containing tobac...
