Definitions

  • the present invention relates to a method of gluing one or more longitudinal zones of a strip of paper intended to form the envelope of a sausage, in particular in the tobacco industry. It also relates to a cigarette filter rod obtained according to the above method.
  • the gluing of the paper strips intended to form the cylindrical casing envelopes, in particular in the tobacco industry, is an operation which must satisfy multiple requirements.
  • the simplest and most widespread solution up to now consists in using a glue liquid at room temperature, for example polyvinyl acetate, and in gluing the bonding zones which will later form the joints, by transfer of this glue liquid on the strip of paper, for example by means of a thin disc driven in rotation of which a part of the periphery is immersed in a container of glue.
  • the patent application document DE-A-34 01 588 describes for example an improvement made to applicators of this kind. Instead of the disc applicators, glue applicators have also been proposed for the deposition of polyvinyl acetate, provided with a nozzle which opens into contact with the paper (US Pat. No. 3,619,328).
  • the aim of the present invention is to propose a simple sizing process making it possible to carry out the sizing operation at high speed on all kinds of paper, in particular highly porous papers, and the costs of which are used are as small as possible.
  • a particularly advantageous application of this process relates to the manufacture of the strands of cigarette filter.
  • Another object of the invention is therefore a cigarette filter rod comprising the characteristics mentioned in claims 8 and 9.
  • a strip of paper l which scrolls at high speed in an installation so as to constitute the envelope of a cigarette filter rod designated by 2.
  • the band l constitutes a cylindrical envelope which surrounds a filtering mass 3 of cellulose acetate and the two edges of which are folded over one another and kept fixed by a glue joint 4.
  • This glue joint is called the seam joint.
  • a second adhesive joint 5 is located in the center of the strip and provides the connection between the filtering mass 3 and the strip l.
  • the strip l permanently receives on its central zone 6 a jet of liquid glue forming the inner seal in the form of a median thread.
  • a jet of liquid glue forming the inner seal in the form of a median thread.
  • a second jet of glue which forms a marginal thread 7 and constitutes the sewing thread.
  • the threads 6 and 7 are approximately 2 mm wide.
  • the strip 1 After having received the glue threads 6 and 7, projected horizontally, the strip 1 is led into a device for forming the flange, which is known per se and is only shown diagrammatically in FIG. l.
  • Guide means lift the edges of the strip to give it the shape of a U in which a continuous bar 3 of cellulose acetate, forming the material of the filter is engaged.
  • the assembly of the strip l and of the filling 3 then passes through a closing guide 27 in which the two edges of the strip l are folded over the mass 3 and pressed against one another, thus ensuring the adhesion of the connecting zones 6 and 7.
  • the sausage is then dried and cut into segments which are incorporated into cigarettes during subsequent operations.
  • the means used to deposit the two adhesive threads 6 and 7 are shown in more detail in FIGS. 2 and 3.
  • Fig. 2 shows the entire planned installation.
  • This installation includes a fully closed glue tank 8.
  • Tubing 9 comes out and leads the liquid adhesive to the two projectors 10 and 11 which are placed in front of the strip l at locations fixed so as to project the adhesive joints 6 and 7 thereon.
  • a tube 12 compressed air is admitted into the upper part of the container 8 in order to pressurize the liquid adhesive contained in this reservoir.
  • a valve 13 and a connector on the pipe 9 make it possible to supply the container 8 with adhesive, if necessary.
  • the installation requires a compressed air supply and adjustment and control means acting on this supply.
  • the control panel 14 comprises, in addition to the control switch 15, regulators 16, 17 and 18 adjustable and consequently making it possible to adjust the pressures of the air going, on the one hand, to the container 8 by the tube 12, d on the other hand, to the projector 10 by a pipe 19 into which a heating device 20 is introduced and finally into a duct 21 which supplies the projector 11.
  • the projection devices 10 and 11 are also supplied with compressed air at unregulated pressure, from a pipe 22, through a control valve 23. This control makes it possible to maneuver the needle of the projectors, as will be seen below.
  • the general supply of table 14 is carried out from a source of compressed air through a presetting regulator 24.
  • the device 10 comprises a nozzle 25 provided with an opening calibrated at its anterior end.
  • a movable needle, visible at 26, is biased by a spring so as to be held in a position where it closes the opening of the nozzle.
  • the air pressure arriving through the conduit 22 causes the needle to retreat and consequently the opening of the nozzle.
  • a mixture of air and liquid coming from the two conduits 9 and 19 is then brought behind the opening of the nozzle and projects a jet of fine droplets of liquid on the strip l which passes at high speed in front of this nozzle, at a certain distance, for example of the order of 4 mm. It has been found that different features make it possible to obtain results which fully satisfy the conditions.
  • the dosage of the adhesive with regard to the degree of fluidity and its capillarity characteristics must be adjusted by means of preliminary tests as a function of the desired running speed and the type of paper to be bonded.
  • the compressed air pressures must be determined from case to case with accuracy, as mentioned above.
  • the diameter of the droplets and the spraying rate depend on the characteristics of the opening of the nozzle as well as the dimensions and the shape of the interior chamber in which the mixing takes place. .
  • the glue which is deposited by projection, in very fine droplets, on the fibers of the paper does not penetrate the thickness of the latter. A reliable connection is thus obtained, in particular at the so-called “sewing” joint, preventing any fouling of the machines, even with highly porous paper.
