Definitions

  • the invention relates to a method for printing on a material web, in particular a paper web, in which a color is applied to the material web, the material web is then dried using heat and then cooled.
  • the invention further relates to a device for printing on a material web with a printing unit, a dryer section and a cooling section.
  • the printing ink When printing on a material web, the printing ink is applied in the majority of cases in liquid form. With the high throughput speeds used today, the ink is usually not sufficiently dry when the paper web leaves the printing unit. In order to be able to immediately follow up with post-processing, for example cutting, folding, folding and When the printed web is stapled, the web is passed through a dryer section in which the printing inks are dried using heat. In the warm state, however, the printing inks have a certain stickiness, which is disadvantageous when folding printed sheets together, because the sheets then adhere to one another. For this reason, the material web is cooled after drying.
  • the invention has for its object to improve the manageability of the material web after printing.
  • This object is achieved in a method of the type mentioned in that the material web after cooling and before further processing is moistened with simultaneous application of heat and then cooled again.
  • the moistening leads to an increase in the moisture of the paper and thus the handling properties are improved.
  • steam is applied to the material web for moistening, which is condensed on the material web.
  • the application of steam has the advantage that there are no droplets which can lead to markings, that is to say an unrest or ripple on the surface.
  • a condensate layer is formed on the paper web, a uniform film is formed which moistens the web accordingly evenly without the formation of markings.
  • the amount of steam supplied is preferably limited so that the steam condenses on the material web without dripping. Even if these drops have no negative effects on the material web due to the lack of limitation, the drops are nevertheless prevented from detaching from the material web and falling off. With such a detachment, the liquid layer on the surface of the material web is made uneven, which is to be avoided in principle.
  • the steam is advantageously brought to the material web from below. This increases the efficiency.
  • the hot steam always tries to rise upwards compared to the colder air. This effect is advantageously exploited when the steam is brought in from below.
  • the cooling is preferably carried out immediately after the vapor deposition. This ensures that only a higher temperature, namely the temperature of approximately 100 ° C., is applied to the surface.
  • the penetration of heat into the interior of the paper web is generally made more difficult by the printing inks or a previously applied line. Of course, the penetration of heat will not completely prevent it. It only takes a certain amount of time. If the cooling takes place immediately after the vapor deposition, the heat is dissipated on the surface again before it can penetrate into the interior of the material web and there lead to changes in the structure.
  • the moistening advantageously takes place in front of a roller which at least partially wraps around the material web with its moistened side. In this way, a gusset is formed between the material web and the roller, in which the moisture of the film formed on the surface of the material web is pressed into the material web.
  • the wrap angle can be relatively small. You only have to ensure a certain contact pressure of the material web against the roller. If necessary, this can also be done by a pressure roller if the wrap angle approaches zero.
  • the material web is preferably moistened in succession from two sides.
  • the two sides are thus treated equally.
  • the successive moistening allows each side to be exposed to moisture under optimal conditions.
  • the object is achieved in a device of the type mentioned at the outset in that, in the running direction of the material web, a moistening section is provided next to the cooling section and then an after-cooling section is provided thereon.
  • the material web is moistened again, in the post-cooling section the temperature increase of the material web that occurred during moistening is reversed again.
  • a material web is available which has improved handling properties, in particular with a lower risk of fold breakage and a reduced curl.
  • the moistening section preferably has at least one steam spray tube directed onto the material web.
  • the steam spray tube generates a directed steam jet, which in this case is directed at the material web at a certain pressure or a certain speed.
  • the jet is able to penetrate the air layer adhering to the material web, so that the steam can condense directly on the surface of the material web, which is still colder due to the preceding cooling section. There it forms a film of moisture that is relatively even. The moisture film then leads directly to a moistening of the material web, at least on its upper side.
  • the steam spray tube is preferably directed towards the underside of the material web. As already mentioned above, this exploits the natural tendency of the steam to rise upwards. There is an improved transport of the steam and thus an improved efficiency.
  • a drip pan is preferably arranged below the steam spray tube. In the event that, despite all precautionary measures, drops form and detach from the material web, for example when the device starts up, care is taken with the drip pan that the water can be removed immediately without causing further damage. This drastically reduces the risk of corrosion damage.
  • the collecting trough preferably has raised side walls which, together with the material web and optionally at least one guide roller, enclose an evaporation chamber.
  • a vapor atmosphere can now form in this vaporization space.
  • the atmosphere in this vaporization space can be free of air. This significantly improves the transition of the steam to the material web, i.e. the formation of the corresponding condensate film. This in turn has the consequence that the humidification takes place with the necessary reliability to the desired extent.
  • the guide roller following the steam spray tube in the running direction of the material web is preferably arranged on the same side of the material web on which the steam spray tube is also arranged.
  • this arrangement enables a gusset to be formed between the guide roll and the web.
  • the moisture on the surface of the material web is absorbed by external forces the material web is pushed in. This drastically shortens the time for moistening the material web. It is also possible in this way to moisten a material web which, due to the printing inks or a line applied earlier, has a reduced permeability to water.
  • the moistening section is advantageously provided with a suction device. As a result, excess steam is drawn off, so that it cannot or only to a small extent precipitate on other parts of the device. This also reduces the risk of corrosion.
  • the moistening section is preferably arranged above the cooling section. There is still enough space available for a normal printing system. This arrangement makes it possible to retrofit existing printing systems.
  • the post-cooling section is preferably arranged directly next to the moistening section.
  • the temperature increase which occurs as a result of the application of steam and which initially occurs on the surface is then very quickly eliminated, so that the heat has practically no or little opportunity to penetrate into the interior of the material web.
  • the post-cooling section is designed as part of the cooling section, from which the material web is led out before its end, passed through the moistening section and fed back in again. This means that practically no additional cooling section is required. Rather, it is integrated into the existing cooling section. The performance of the existing cooling section is often sufficient or even dimensioned too high, so that these power reserves can be used to carry out the humidification with subsequent cooling.
  • a device 1 for printing on a paper web 2 has a printing section 3, shown only schematically, in which one or more colors are applied to the paper web 2 in a known manner.
  • the printing section 3 is followed by a dryer section 4, in which the paper web 2 is dried using heat.
  • the dryer 4 is followed in the running direction 5 by a cooling section 6 which, in a known manner, has cooling rollers 7, six in the illustrated case.
  • the paper web 2 is guided over these cooling rollers 7 with the largest possible wrap angle.
  • the cooling rollers can, for example, be water-cooled. They serve to remove the heat introduced into the paper web 2 in the dryer section 4 and thus to lower the temperature.
  • a processing section 8 is usually provided behind the cooling section 6, in which the paper web is cut, folded, stapled or bound or further processed in another way.
  • the paper web is still guided between the cooling section 6 and the processing section 8 through a moistening section 9, which is followed by a post-cooling section 10.
  • the moistening section has a web guide with a plurality of guide rollers 11 to 16, the paper web 2 being guided essentially horizontally between two guide rollers 12, 13 and 15, 16, respectively.
  • steam spray pipes 19, 20 are arranged so that they direct a steam jet against the respective underside of the paper web 2. Since the paper web 2 has previously been passed through the cooling section 6, ie has a correspondingly low temperature, the steam guided by the directed steam jet to the paper web 2 can condense there. It forms a film of moisture that is relatively even. Droplet formation is almost completely avoided in normal operation. This can be achieved in particular by controlling the amount of steam emitted so that only as much steam is emitted as can actually condense on the paper web.
  • the guide rollers 13, 16 following the steam spray tubes 19, 20 are arranged in such a way that the paper web 2 at least partially wraps around these guide rollers 13, 16.
  • a gusset 21, 22 is thereby formed, in which the moisture layer on the surface of the paper web 2 is pressed into the paper web 2, so to speak. This improves the absorption of moisture.
  • a collecting trough 23, 24 is arranged below each of the steam spray pipes 19, 20, so that water accidentally falling down is caught in the form of droplets and can be removed. Such Under unfavorable circumstances, water drops can form when starting up or restarting the device 1.
  • the collecting troughs 23, 24 have side walls 25, 26 which are drawn up so that they each have a vaporization space 27, together with the paper web 2, more precisely its sections 17, 18, and the guide rollers 12, 13 and 15, 16, Include 28.
  • These steaming spaces 27, 28 can be completely filled with steam, i.e. be practically air-free, so that the transfer of moisture with the help of steam to the paper web 2 is further improved.
  • the moistening section is also provided with a suction device 29, through which superfluous steam can be sucked off, for example with the aid of a fan 30. If necessary, the extracted steam can also be returned.
  • the after-cooling section 10 is connected to the moistening section with two further cooling rollers 31, which reverses the temperature increase of the web 2 that has occurred in the moistening section.
  • the paper web 2 then runs in the usual way into the processing section 8 in order to be further processed there, as mentioned above.
  • the moistening section 9 is arranged above the cooling section 6. Appropriate space is available there.
  • the after-cooling section 10 is immediately adjacent to the moistening section. In the illustrated embodiment, it is also arranged above the cooling section 6.
  • the after-cooling section 10 ' is now part of the cooling section 6'.
  • the paper web 2 in the cooling section 6 ' is no longer passed over six cooling rollers 7 but only over four cooling rollers 7 before entering the moistening section 9.
  • the paper web 2 is led out of the cooling section 6, passed through the moistening section 9 and fed back into the cooling section 6 ', where it loops around a further two cooling rollers 7.
  • a separate assembly for the after-cooling unit 10 is saved.
  • only a few cooling rollers 7 are available in the cooling unit 6 '. In many cases, however, this is not critical because the cooling rollers 7 often have sufficient power reserves.
