Definitions

  • the invention relates to a method for producing tobacco smoke filter rods, in particular cigarette filter rods, filter dew being drawn from a supply and consisting of crimped staple fibers and / or filaments - Spread, loosened, stretched, relaxed and, if necessary, provided with a plasticizer in a preparation zone and - Is then fed to a processing zone, where it is combined in an inlet zone, then optionally wrapped with a wrapping strip and finally cut into individual tobacco smoke filter rods as a tobacco smoke filter strand.
  • the invention also relates to devices for carrying out the method in each case a preparation device which has devices for spreading, loosening, stretching and relaxing the filter rope and, if appropriate, a device for providing the filter rope with plasticizer, and -
  • a processing device which optionally has an inlet nozzle for conveying the filter rope, furthermore an inlet device for combining the filter rope with possibly an inlet funnel and with an inlet finger, also optionally a wrapping device for wrapping the filter rope with a wrapping strip and a cutting device for cutting the formed tobacco smoke filter strand into individual ones Has tobacco smoke filter rods.
  • filter tow means a fleece made from a multitude of crimped e.g. synthetic staple fibers and / or filaments.
  • the filter rope can consist, for example, of crimped cellulose acetate, in particular cellulose 2,5-acetate staple fibers and / or filaments.
  • the known devices for producing tobacco smoke filter rods are normally composed of a processing device and a processing device.
  • the processing device usually has devices for spreading, loosening, stretching and relaxing the filter rope and, if the filter rope is to be provided with plasticizer, a device for wetting the staple fibers and / or filaments of the filter rope with a plasticizer.
  • the processing device usually has an inlet device for combining the filter dew with an inlet funnel and an inlet finger, moreover, if the filter rope with e.g. Paper to be wrapped, a wrapping device for wrapping the filter rope with a wrapping strip and a cutting device for cutting the tobacco smoke filter strand formed by the combination and optionally wrapping into individual tobacco smoke filter rods.
  • the inlet funnel is preceded by an inlet nozzle for conveying the filter dew, the inlet funnel then having holes in its wall for the escape of the gas, which is preferably air, fed through the inlet nozzle from the Has inlet funnel.
  • the - endless - filter rope made of, for example, crimped cellulose-2.5-acetate staple fibers and / or filaments, which is stacked on top of one another and thus pressed into a bale, is removed from the surface this bale is continuously drawn off, spread out, guided over a roll or a similar guide element, then spread again, guided by brake rollers, stretched, relaxed, again spread, sprayed with plasticizer, passed over deflection rollers, through an inlet nozzle and from there through a Inlet funnel and an inlet finger guided and optionally wrapped with a wrapping strip made of paper, for example, after which the tobacco smoke filter strand thus formed is cut into finished tobacco smoke filter rods.
  • the filter rope With the stretching of the filter rope, it is achieved that the crimped staple fibers and / or filaments separate from one another. During the subsequent relaxation, the filter rope contracts due to its elasticity under the formation of bulges. The ability to form bulbs depends on whether the stretching is optimal, ie not too weak, so that a complete fiber separation takes place, but also not too strongly, so that no plastic deformation occurs.
  • the known methods and devices for producing tobacco smoke filter rods have the following disadvantages: - With increasing speed and possibly also increasing bulk of the filter rope, the friction between the filter rope and the surrounding air in the area between the deflecting rollers and the inlet nozzle increases, which increases the tendency to wrap on the deflecting rollers, which means that the filter rope is easily around the Deflection rollers can wrap. In order to safely pull the puffy filter rope away from the deflection rollers, the pressure of the gas with which the inlet nozzle is operated must be increased. - The puffy filter rope is pressed by the gas flow, which is preferably an air flow, out of the inlet nozzle into the inlet funnel and the following inlet fingers.
  • the gas flow which is preferably an air flow
  • the amount of filter dew to be introduced into the inlet finger is limited by the frictional forces of the filter dew material against the inner wall of the inlet funnel and against the inner wall of the inlet finger, by the friction of the staple fibers and / or filaments against one another and by the rigidity of the staple fibers and / or filaments.
  • the homogeneity i.e.
  • the material characteristic curve shortens (the material characteristic curve is the relationship between the tensile resistance and the filter rope weight, which is suitable for a specific tobacco smoke filter rod format with a filter rope on a device for manufacturing of tobacco smoke filter rods).
  • the invention has for its object to provide a method of the type mentioned for the manufacture of tobacco smoke filter rods, in particular cigarette filter rods, with the - With increasing speed and possibly also increasing bulk of the filter rope, the formation of coils on the deflecting rollers is avoided, the inlet nozzle pressure need not be increased or even reduced, or the inlet nozzle may even be dispensed with; - More filter thaw material can be introduced into the inlet finger and thus into the finished tobacco smoke filter rods, these filter rods having a uniform tensile resistance, and the inlet nozzle pressure does not have to be increased or even reduced, or it is even possible to dispense with the inlet nozzle; - At higher working speeds, an extension of the material characteristic and at the same time A uniform tensile resistance of the finished tobacco smoke filter rods can be obtained, the inlet nozzle pressure need not be increased or even reduced, or the inlet nozzle can even be dispensed with.
  • the invention is also based on the object of providing a device for carrying out the method according to the invention.
  • the invention has the following advantages: - The formation of coils on the deflecting rollers of the devices for producing tobacco smoke filter rods is avoided; - With a given filter weight per tobacco smoke filter rod and a given draw resistance - compared to the state of the art - the inlet nozzle pressure can be reduced, so that the homogeneity of the mass of the filter dew in the finished filter rods is improved and thereby in turn a uniform draw resistance over the length of the filter rods and of the rod Rod can be reached; - By the action of a gas or vapor increased pressure in the area of the inlet zone on the filter rope in its direction of movement, the spun fibers and / or filaments of this filter rope are apparently swirled a lot, because compared to a tobacco smoke filter rod manufactured according to the prior art with the same filter rope weight increases after the invention of the draw resistance.
  • the invention requires less filter dew per tobacco smoke filter rod for a given draw resistance; -
  • the material characteristic can be extended even at higher working speeds and thus achieve a uniform tensile resistance over the length of the finished tobacco smoke filter rods and from rod to rod; -
  • the inlet nozzle pressure does not have to be increased even at higher working speeds or can even be lowered, or the inlet nozzle can even be dispensed with; -
  • the filter rope no longer needs to be drawn by hand under the inlet finger to the format belt, because the gas - or the corresponding steam - which is led through the holes in the wall of the inlet finger - or the corresponding steam - transports the filter rope automatically to the format tape.
