Definitions

  • the present invention relates to a method and system of making tobacco pouches.
  • tobacco pouches are made from a film material which is provided on a roll.
  • the film material on the roll is pre-printed and may be a multi-layer or a single layer film material.
  • the film material is unrolled from the roll and guided through an assembly line (or system) for making the tobacco pouches.
  • the film material is folded onto itself in order to form the compartments of the tobacco pouches.
  • seams are made with a heat welding device.
  • the film material melts and forms a weld which interconnects two parts of the film material which are folded onto one another.
  • the seams extend transverse to the main direction of the film material and form the left side and right side of a the compartment of each tobacco pouch.
  • the tobacco pouches are cut along predefined cutting lines into individual tobacco pouches. Each cut divides the seams in a first and second seam section, wherein the first seam section forms the left side of a leading pouch and the second seam section forms the right side of a trailing pouch.
  • the making of the tobacco pouches is often integrated with a filling assembly line, so that the tobacco pouches are filled with tobacco directly after they are made.
  • the tobacco pouches have a mouth which should be open during filling. Further, the mouth should be closed directly after filling in order to keep the tobacco fresh. Furthermore, a user should be able to open the mouth without too much difficulty when he starts to take tobacco from a new tobacco pouch.
  • a non-permanent seal in the form of wax is generally used to close the mouth. Both sides of the film which engage one another at the mouth are provided with a wax layer.
  • the wax acts as a kind of adhesive and keeps the mouth closed before first use. This keeps the tobacco fresh.
  • the adhesive strength is weak enough to allow the user to open the mouth. In this way, the wax creates a non-permanent seal at the mouth.
  • the wax is generally applied on the film material upstream of the pouch making assembly line and is often provided on the film material in two long bands, which extend lengthwise of the film.
  • the wax bands are as long as the film itself.
  • the wax bands are generally provided by the manufacturer of the film material which can be a different party as the party which makes the pouches and fills the pouches with tobacco. This method of applying the wax has a proven track record and has been used for a number of years.
  • Document EP 1 683 763 A2 for example discloses a method of manufacturing a tobacco pouch, the method comprising: unrolling a film material from a roll, conveying the unrolled film material along an adhesive strip application station, and applying strips of adhesive material on the film material, folding the film onto itself along at least one bottom fold which extends lengthwise of the film material, conveying the film material along a first heat welding station and providing a right seam and a left seam in the first heat welding station along at least a right side and a left side of the tobacco pouch which is to be formed, the left and right seam extending transverse to a main longitudinal direction of the film material, conveying the film material along a cutting station and cutting the film material at regular intervals to form individual tobacco pouches.
  • EP 1 683 736 A2 also discloses a tobacco pouch making system for performing such a method. Furthermore, EP 2 532 513 A2 discloses a method and related system for making tobacco pouches, wherein the film for making the pouches is provided with strips of adhesive material positioned in rows at regular intervals.
  • the wax bands run along the entire length of the film.
  • the seams are made with heat welding, the seams cross the bands of wax.
  • the heat welding does not result in a high quality weld, because the wax prevents a high quality weld.
  • the two parts of the film material may come loose quite easily, resulting in holes in the compartment at the left and right side of the pouch. The crossings form weak spots. This is explained further in the figures relating to the prior art.
  • Another aspect of the background of the present invention is that tobacco pouches are subject to increasingly strict legal requirements.
  • the size of the flap is regulated in the sense that the size of the flap is reduced to a certain maximum size.
  • many users wish to fold the flap around the tobacco pouch after first use of the tobacco pouch, and this requires a rather large flap.
  • the limited size of the flap according to health warning regulations therefore may have a negative effect on the user friendliness of the tobacco pouch. It was recognized in the present invention that there is no good solution for this problem with current systems for making tobacco pouches.
  • the known method does not allow much variations in the position of the wax bands in the pouch. It was recognized that a different method of applying wax on the film material could result in a more versatile system and method of making tobacco pouches and overcomes the known disadvantage of the prior art.
  • the invention provides a method of manufacturing a tobacco pouch according to claim 1 the method comprising: unrolling a film material from a roll, conveying the unrolled film material along an adhesive application station comprising an adhesive nozzle, and applying at last one row of adhesive regions on the film material at regular intervals by ejecting a volume of adhesive from the at least one adhesive nozzle at regular intervals, folding the film onto itself along at least one bottom fold which extends lengthwise of the film materials, conveying the film material along a first heat welding station and providing a right seam and a left seam in the first heat welding station along at least a right side and a left side of the tabacco pouch which is to be dormed, the left and right seam extending transverse to a main longitudinal direction of the film material, conveying the film material along a cutting station and cutting the film material at regular intervals to from individual tabacco pouches.
  • tobacco pouches can be made without weak spots in the side seams.
  • the flap can be made to fold onto itself.
  • greater variations in non-permanent seals are possible, because the adhesive nozzles can be configured to apply adhesive in a variety of ways.
  • the adhesive regions of at least one row meet the left seam and right seam or end at a distance from the left seam and right seam and do not extend into the left seam and right seam.
  • each adhesive region of adhesive material comprises opposite ends, wherein the ends meet the right seam and left seam or are located at a distance from the right seam and left seam.
  • each adhesive region is elongate and has a shape of a band, wherein the elongate bands extend parallel to the main longitudinal direction of the film material.
  • the method comprises applying first bands and second bands of adhesive at regular intervals along the film, wherein the first and second bands of adhesive are folded onto each other by the making of the at least one bottom fold.
  • the first bands and second bands of adhesive have a substantially same length and a substantially same width and are provided on either side from the bottom fold at a same distance from the bottom fold.
  • the film material on the roll is free of any bands of adhesive.
  • the adhesive is wax. Wax has very good properties for forming non-permanent seals.
  • the adhesive is hot-melted and subsequently applied as hot-melt.
  • the liquid or almost liquid form of the hot-melt adhesive makes it suitable to be applied via nozzles which engage the film material.
  • the method comprises activating the one or more adhesive nozzles for a predetermined first period of time, and de-activating the adhesive nozzles for a predetermined second period of time, and repeating these steps for each tobacco pouch.
  • the method comprises:
  • the method comprises:
  • At least one flap adhesive region straddles the cut line along which the film material is cut into individual pouches, the method comprising cutting through the flap adhesive regions during the cutting of the film material to form the individual pouches.
  • the at least one flap adhesive region has the shape of an elongate band, wherein the at least one flap adhesive region extends at right angles to a main longitudinal direction of the film material.
  • the adhesive is applied to the film material while the film material is being conveyed along the at least one adhesive nozzle.
  • the nozzles engage the film material while the film material is being conveyed along the at least one adhesive nozzle. To this end, the nozzles are pressed against the film material. The pressing is carried out gently.
  • the adhesive is applied to the film material while the film material is being conveyed along the at least one adhesive nozzle in an upward direction, in particular vertically upward.
  • the present invention further relates to a tobacco pouch making system for making tobacco pouches according to claim 7, the tabacco pouch making system comprising: a roll support for supporting a roll of film material, multiple guides for guiding the film material, an adhesive application station comprising at least one adhesive nozzle for applying one or more rows of adhesive regions onto the film material by ejecting a volume of adhesive from the at least one adhesive nozzle at regular intervals, a folding station for folding the film material onto itself along at least one botton fold which extends lengthwise of the film material, a heat welding station comprising at least one heating element for making a right seam and a left seam in the film material for forming a right side a left side of the tabacco pouches which are to be formed, a cutting station for cutting the individual tabacco pouches form the film material, wherein the adhesive application station comprises at least one flap adhesive nozzle configured for providing at least one row of flap adhesive regions on a section of the film material which forms the flap, the tabacco pouch making system comprising a flap folding station a front
  • the adhesive application station comprises a control unit configured for activating and de-activating the adhesive nozzle for applying at least one row of elongate bands of adhesive at regular intervals and with adhesive-free zones between the adhesive bands, wherein the at least one row of elongate adhesive bands extends parallel to a main longitudinal direction of the film material.
  • the tobacco pouch making system comprises a first adhesive nozzle and a second adhesive nozzle positioned at a distance from one another and configured for applying a first row of adhesive regions and a second row of adhesive regions at regular intervals along the film, wherein in particular the folding station is configured for folding the first and second adhesive regions onto each other.
  • the first and second adhesive nozzles are configured for applying the first adhesive regions and second adhesive regions with a substantially same length and a substantially same width and at a substantially same distance from the bottom fold.
  • an outflow opening of each nozzle has an elongate shape, having a length and a width, wherein the length of the outflow opening is more than 10 times the width, in particular more than 30 times the width.
  • each nozzle has a single outflow opening.
  • the tobacco pouch making system comprises a further heating element for heating the flap adhesive regions of the folded flap in order to provide a non-permanent seal which interconnects the front flap part onto the rear flap part of the folded flap.
  • the adhesive application station comprises a reservoir which holds adhesive, such as wax.
  • the heat welding station welds the seams and also heats the adhesive regions to form non-permanent seals.
  • the tobacco pouch making system comprises a second heat welding station positioned downstream from the cutting station and configured for applying heat at the mouth of the tobacco pouch, thereby melting the adhesive and closing the mouth of the compartment with a non-permanent mouth seal.
  • the adhesive application station is configured to apply adhesive while the film material is being conveyed along the at least one adhesive nozzle.
