Loss of tobacco from the ends of cigarettes is reduced or prevented by applying foamed adhesive thereto. The foam may in general be blown onto the cigarette ends or may be "printed" onto the cigarette ends. The expansion ratio of the foam in preferably at least 10:1, so that very little liquid adhesive is needed to contact a significant area of tobacco. Thus the liquid content of the adhesive may be readily absorbed into the tobacco so as not to create a drying problem. In a preferred example foam is supplied by a pipe to fill apertures on a disc from which measured quantities of foam are blown by an air jet from a pipe. Suction is applied to the filter ends of the cigarettes via a manifold and flexible seals to help in drawing the foam into the cigarettes.
A method of treating cigarettes in which the cigarettes are conveyed sideways past an adhesive applicator whereby a measured quantity of foamed adhesive is applied to the tobacco end of each cigarette by pneumatically transferring a measured quantity of the foamed adhesive from said adhesive applicator toward and onto the tobacco end of each cigarette to secure the tobacco in the cigarette.
A method of treating cigarettes in which the cigarettes are conveyed sideways past an adhesive applicator whereby a measured quantity of foamed adhesive is applied to the tobacco end of each cigarette by pneumatically transferring a measured quantity of the foamed adhesive onto the tobacco end of each cigarette to secure the tobacco in the cigarette, the measured quantities of adhesive being produced by filling apertures in a moving disc with foam, and in which the foam in each aperture is pneumatically transferred onto the corresponding cigarette end.
A method of treating cigarettes in which the cigarettes are conveyed sideways past an adhesive applicator whereby a measured quantity of foamed adhesive is applied to the tobacco end of each cigarette by pneumatically transferring a measured quantity of the foamed adhesive onto the tobacco end of each cigarette to secure the tobacco in the cigarette, and in which, while foam is being applied to one end of each cigarette, suction is applied to the other end to assist in drawing the foam into the cigarette.
Apparatus for treating cigarettes to reduce the loss of tobacco from the ends, comprising a conveyor for conveying cigarettes sideways along a predetermined path, means adjacent to the path for generating individual measured quantities of foamed adhesive, and means for pneumatically transferring a respective measured quantity of the foamed adhesive from said generating means toward the path and onto one end of each cigarette.
