Definitions

  • the present invention relates to a gumming procedure used in the manufacture of continuous wads of reconstituted tobacco sheets. Its field of application is that of articles for the smoker and in particular that of a set of reconstituted tobacco sheets gummed and bound to each other in such a way that they may be dispensed automatically by pulling on them gently. In this way, the smoker may use the reconstituted tobacco sheet either for rolling shredded-leaf tobacco or else for smoking the actual rolled tobacco sheet.
  • BOLLORE document FR 2 772 237 takes up the idea of US patent 5762074 , but proposing a presentation with the sheets collated instead of being joined to each other by one of their edges.
  • the likewise BOLLORE document FR 2 785 504 acknowledges the scant adhesive properties of the gumming according to FR 2 772 237 due to the high capacity of adhesive absorption by the reconstituted tobacco sheet, which leaves too small an amount of adhesive free in order to be able to fulfil its function.
  • the solution proposed consists of increasing the amount of adhesive used considerably, up to values above 70 mg/m. These high values give rise to a new problem, consisting of the fact that, although it fulfils its function, the band of adhesive becomes rigid and brittle, so that its drying has to be strictly controlled to ensure that it takes place slowly and without the moisture content dropping overly, which is achieved by spraying with water.
  • Such a solution entails a higher cost, both on account of the adhesive used and the additional means needed during drying.
  • the invention is based on depositing a minimum quantity of adhesive and preventing its absorption by the sheet. It has been found that the presence of 20-25% of water at the time of gumming permits the depositing of layers of adhesive of a linear thickness of less than 60 mg/m, which surprisingly enough have an excellent sticking capacity.
  • the necessary subsequent adhesive drying operation is carried out in a conventional way without any need for spraying with water, as we start with very high initial values for the moisture content and the thickness of adhesive deposited is very low.
  • the little adhesive used lies "outside" the sheet, so it is highly effective.
  • the control of the attractive stress of the rollers makes it possible to adjust the quantity of water retained precisely, so as to obtain a moisture content 20% or more and, therefore, the adhesive absorption capacity of the reconstituted tobacco sheet.
  • the surplus water is evaporated during the adhesive drying operation until the moisture is reduced to the optimum values for the actual reconstituted tobacco sheet, which, as is common knowledge, should lie between 7-10%.
  • the final operation will consist of joining up a plurality of individual sheets, either by means of a light adhesive along one of their edges or else through mere collation, using processes that are common knowledge.
  • the gum used for applying the band of adhesive to one of the margins of the reconstituted tobacco sheet is an adhesive for food products, the same as that used for paper for rolling cigarettes, and it is applied in a conventional way so that the amount of adhesive in a dry state is in the range between 45-60 mg/m.
  • the method of the invention is integrated in a system of continuous manufacturing of pads of gummed and interlinked sheets, of variable format in width and length, so that, starting from one or two pairs of input rolls of the necessary width for obtaining the required number of sheets, as many bands of adhesive as may be needed are applied to each of the rolls so as to proceed afterwards to the drying of the adhesive and terminate with the longitudinal cutting of the strips of paper, trimming, conveyance and storage of the selvedges.
  • These strips obtained from the cutting will be folded in half and the sheets of gummed paper will be bound to each other to form a continuous pack which will be cut transversely to the desired length of the pads of gummed and bound sheets for stacking for their storage and subsequent boxing.
