Abstract: A device for measuring the draft of cigarettes comprises a vertical tubular body in which cigarettes are fed one by one. A first sphincter-member mounted inside the body is operable to prevent a cigarette from falling and stop it in a given position. A second sphincter-member positioned above the first member is actuated when the first member is released so as to hold the cigarette in the above given position. A seal is provided at the bottom side of the tubular body to define a gas-tight chamber with the second sphincter-member, and an orifice connected to a source of air under vacuum is formed in the body between the first sphincter-member and the seal.

Abstract: A smokable material for the tobacco industry, characterized in that it is formed in its major part with coherent spheroidal aggregates of entangled tobacco fibers having no preferential direction.

Abstract: Glue for articles of the tobacco industry such as cigarettes, cigarillos, cigars, filter tips, coupling-sleeves, etc., characterized by the fact that at ambient temperature it is in gel form composed mainly of water and gelatine, the gelatine concentration being in the 25-180% range in relation to the water weight, and a minor quantity of plasticizer for the gelatine in aqueous solution, belonging to the food polymers group comprising natural and modified vegetable gums and cellulose ethers, the plasticizer's concentration being within the 0.25-8% range in relation to the weight of the gelatine alone, and being adjusted so that the temperature at which the liquefied gel viscosity remains superior to 50 centipoises and becomes lower than 1000 centipoises is within the 40-70.degree. C. range.
