Abstract
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° C. range.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
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 consisting essentially 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, selected from the group consisting of sodium alginate, carragenate, guar gum, gum arabic, pectine, galactomanne methylcellulose, sodium carboxymethylcellulose and acetylated starch, 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° C. range.
Claim 2
Dependent Claim
129 words

Claim 3
Dependent Claim
72 words
Glue according to claim 1, characterized by the fact that the gelatine concentration is within the 30-50% range in relation to the water weight, the plasticizer concentration is within the 0.5-4% range in relation to the weight of the gelatine alone, and is adjusted so that the temperature at which the liquefied gel viscosity remains superior to 70 centipoises and becomes lower than 850 centipoises is within the 45-65 degrees centigrade range.
Claim 4
Dependent Claim
17 words
Glue according to claim 2, characterized by the fact that the plasticizer is a water soluble alginate.
Claim 5
Dependent Claim
18 words
Glue according to claim 2, characterized by the fact that the plasticizer is a water soluble cellulose ether.
Claim 6
Dependent Claim
15 words
Glue according to claim 3, characterized by the fact that the plasticizer is sodium alginate.
Claim 7
Dependent Claim
14 words
Glue according to claim 4, characterized by the fact that the plasticizer is carboxymethylcellulose.
Claim 8
Dependent Claim
24 words
Glue according to claim 1, characterized by the fact that the plasticizer ponderal concentration in relation to gelatine is of the order of 1%.
Claim 9
Dependent Claim
27 words
Glue according to claim 1, characterized by the fact that the gelatine ponderal concentration in relation to the weight of water is of the order of 40%.
Claim 10
Dependent Claim
103 words
Process for preparing a glue according to claim 1 characterized by the fact that it comprises dissolving in water maintained between 50° and 70° C. a quantity of gelatine such as the ponderal concentration of the gelatine in relation to water be within the range of 25 and 60%, determining the stoichiometric proportions of the plasticizer on samples in order to limit the solution viscosity at the preparation temperature between 60 and 1000 centipoises, mixing the smallest of the quantities of plasticizer so determined and corresponding to the weight of gelatine used with the solution and cooling the mixture down to ambient temperature.
