Definitions

• cigarette-paper should be considered as being an integral part of tobacco and'it shoull have even been made todo its share towards the improvement of the qualities, the taste and the flavour of the weed.
• the part played by cigarette-paper should have been similar to that of'the external leaf Wrapped round a cigar. Nevertheless, no serious investigation has ever been undertaken to examine the possibilities of eliminating or neutralising the acrid taste,
• WVhile remaining, as hithereto, thin, silky, White, opaque and combustible, cigarettepaper should contain inits cellulose texture certain essential elements, such as are to be found in high class oriental tobacco, principally aromatic resin-gums and ,glucosides.
• High class oriental tobaccos owe their fragrant and mellow taste to the presence oi those essential elements which exist in the pulp of their leaves, also, they owe the characteristic soothing and delicate aroma of their smoke to the distillation of these elements when making cigarettes.
• vapours of those aromatic resin-gums and the products of the distillation of the glucosides alone are able to sweeten and neutralise the sharp taste andcaustic flavour of the smoke due to the combustion of the cellulose albumins and other constitutive elements of tobacco.
• the process, object of this invention is one which allows the incorporatlon, 1n the cigarette-paper'pulp, at a suitable stage of man ufacture and especially'in the last beating, of a natural. or artific1al, gum containing soothing and sweetening elements such as aromatic resin-gums, for instance, arabic gunnadraganthin and more especially gum known 'as mastic-gum which, thanks to its. viscous nature, is retained in the paper pulp carried away by the water and cannot be which is driven out of the pulp during the manufacture of the paper;
• soothing and sweetening elements such as aromatic resin-gums, for instance, arabic gunnadraganthin and more especially gum known 'as mastic-gum which, thanks to its. viscous nature, is retained in the paper pulp carried away by the water and cannot be which is driven out of the pulp during the manufacture of the paper;
• Mastic resin-gums are obtained by cutting into the bark of certain shrubs of the pisgroWn mainly in the island of Chic in the'G-recian archipelago'and in the neighbourhood of Smyrna. v
• This paper is of silky texture in appearance, with normal strength, absolutely white and opaque and in no way different from ordinary cigarette-paper.
• composition of the cellulosic pulp of this new paper is absolutely the same as the one used for manufacture of ordinary cigarette-paper; the invention consists in incorporating with such pulp 3 to 5% mastic resin-gums, prepared in a solution in the following manner:
• the mastic gum is previously macerated for 24 hours in a hermetically closed container, with, for example, eight times its acetone and twice its weight in alcohol. Sugar may be added to the extent of 2% of the dry weight of the paper pulp which is being subjected to the treatment.
• the incorporation of the gums with the paper paste can also be effected as follows
• the gums are first pulverized and dried and afterwards dissolved in acetone or another solvent of the same chemical nature. gum to the acetone may vary from 1 to 5 per cent.
• the invention is applicable to manufac ture of cigarette-paper for all purposes.
• a process for the manufacture of cigarette paper as claimed in claim 1 further characterized in that to the paper pulp, in the last beating before the pulp is poured into the vat, is added a 3 to 5% quantity of masticresin-gum macerated for 24; hours in a hermetically closed receptacle with eight times its weight in acetone and twice its weight in alcohol.
• a process for the manufacture of cigarette paper as claimed in claim 1 further characterized in that to the said mastic-gum is added a quantity of sugar equal to about 2% of the dry weight of the paper pulp to be treated.
• a process for the manufacture of cigarette paper as claimed in claim 1 further characterized in that mastic gum from p1s tachio shrubs, is used for preparing the solution.
• a process for the manufacture of cigarette paper as claimed in claim 1 further characterized in that the gum solution is incorporated hi the cigarette-paper by aspersiou or steeping of that paper when it leaves the machine.
• the natural gum being the gum known as masticgum.
• Cigarette paper which is on combustion, free from a disagreeable and caustic flavour and manufactured from pulp in which is incorporated a natural gum contaming soothing and sweetening elements.
• Cigarette paper which is on combustion, free from a disagreeable and caustic flavour and manufactured from pulp in which is incorporated an aromatic resin gum.
• Cigarette'paper which is on combustion, free from a disagreeable and caustic flavour and manufactured from pulp in which is incorporated adraganthin.
• Cigarette paper which is on combu tion, free from disagreeable and caustic flavour and manufactured from pulp in which is incorporated arabic gum.
• Cigarette paper which is on combustion, free from a disagreeable and caustic flavour and manufactured from pulp in which is incorporated mastic gum.
