Definitions

  • the invention relates to a method and a device for moistening a printed and then thermally dried, moving material web according to the preamble of claims 1 and 13 respectively.
  • paper webs are printed at high speed and then subjected to a thermal drying process for drying and solidifying the printing inks. It is necessary moisten the printed paper web before final processing to ensure the original paper moisture and thus the elasticity and dimensional stability of the paper required for the final processing. This is necessary because dry paper is very brittle and therefore easily breaks or tears when folded or cut. In addition, dry paper expands when it absorbs moisture from the air. B. comes with glued magazines or the like to an unsightly curl of the finished magazines and to an uneven "outgrowth" of the individual pages in the cutting areas.
  • a material web is subjected to a corona treatment before a dampening solution is applied to it in a moistening station, as a result of which a large number of adhesive adhesion centers are created for the adhesion of the dampening solution particles should.
  • a dampening solution bath or a spray device (not described in detail) is used as the moistening station.
  • the paper web is guided with its one side in contact with an endless belt, the top of which carries a high-voltage conductive coating.
  • a conductive atomizer is provided to form dampening solution aerosols and is arranged on the other side of the paper web at a distance from it. Between the atomizer and the conductive coating a strong electric field is built up, through which the aerosols are polarized and then accelerated so that they not only wet the paper web, but also penetrate into its pores.
  • a disadvantage of this known device is that high voltages in the range of 50 kV have to be used at relatively high powers, so that the humidification device is very sensitive to fluctuations in air humidity, since spark discharges can occur if the air humidity is too high and damage the paper web cause. In addition, complex shielding measures must be provided for safety reasons.
  • Another disadvantage is that this known device requires a relatively large amount of space, so that it cannot be retrofitted to existing printing machines or other processing machines.
  • an applicator roller for applying a dampening solution to a material web, which roller is wetted by a scoop roller immersed in a dampening solution bath.
  • the application roller is pivoted against a web of material or paper so that it deflects it out of its transport path. This ensures that the material web moving over the application roller more or less grinds off the dampening solution film located thereon. Since in this device the material web lies unevenly on the application roller, it is necessary to press the dampening solution evenly through a printed surface of the material web not possible. In addition, the exact dosage of the dampening solution required cannot be achieved.
  • a method and a device is known by which a transfer of a dampening solution to the printed side of a material web is accomplished in a similar manner.
  • the material or paper web is first thermally dried after printing, then cooled and guided over a cooled guide element in the form of a rotating cooling roller.
  • the paper web on a flat side of the web is wetted with a dampening solution or water film for rewetting the web.
  • the water film is first applied to a transfer roller of a roller arrangement and then rolled onto the circumference of the cooling roller by the latter.
  • the paper web wraps around the cooling roller under its own tension in such a way that a large part of its roller circumference is exposed for unrolling the transfer roller.
  • the transfer roller is moistened by means of a roller arrangement which draws the water from a water trough.
  • the invention has for its object to rewet thermally dried and printed material webs, in particular paper webs, at a very high transport speed or in minimal time from their flat side of the web, in order to reduce the moisture loss caused by the drying process with all its disadvantages for the further processing of the material web (folding and folding largely compensate for paper webs).
  • a material web after it has been dried, is wetted on at least one side with dampening solution, which is pressed into the web at the same time.
  • the dampening solution is applied and pressed in at the earliest possible point in time, during the cooling phase, i.e. as soon as the printing ink is so solid that it no longer smears when the dampening solution is pressed in, thus preventing the printed image from being impaired.
  • the dampening solution is applied during the cooling phase, the absorption of the dampening solution into the material web, which is in particular a paper web, is supported by its cooling behavior.
  • the penetration of the dampening solution into the material web can advantageously be supported in that, according to claim 2, the material web wetted with the dampening solution is then passed through an electrical high-voltage field and is thus electrostatically charged.
  • the dampening solution film which after application can still have certain irregularities, is compensated in such a way that it is uniform over the entire width of the material web and adheres well to the material web.
  • small fountain solution droplets are prevented can release from the dampening medium applied to the material web, even if the material webs, such as paper webs in web offset printing, are moved at high transport speeds.
  • the dampening solution can penetrate the relatively warm paper better through the printing ink. As a result, the paper already has improved elasticity during the subsequent treatment.
  • the electrostatic charging is advantageously carried out with a high voltage below 50 kV. Only low electrical power is required, so that, carried out with high voltages, no undesirable spark discharges are to be feared, even with fluctuating air humidity. Because of the low currents required for the electrostatic charging, only relatively simple shielding measures are required for the parts carrying the high voltage, without the safety for a maintenance person being impaired thereby.
  • the penetration behavior of the dampening solution can be additionally influenced and kept constant for a given dampening solution. This enables good and even rewetting to be achieved.
  • the method according to the invention can advantageously be carried out using a device according to claim 13, claims 14 to 16 relating to expedient embodiments of this device.
  • a device for moistening a material web can be retrofitted in a particularly favorable manner into an already existing material web processing machine, since already existing transport and guide rollers can be used for the device according to the invention in this machine.
  • the cooling rollers can be used as guide elements of the device according to the invention without major changes to the cooling station being necessary to install the device according to the invention can.
  • the device according to the invention can be made extremely space-saving.
  • the uniform formation of the dampening solution film and its transfer to the material web surface can be achieved particularly well by designing the device according to claims 20 to 25.
  • a material web 10 to be moistened is guided over an electrically conductive, preferably driven roller 11 serving as a guide element and thereby moved in the direction of arrow B.
  • an application device 12 for applying a dampening solution film to the material web 10 which has a spraying device 13 and a roller arrangement with a first and a second roller 14 and 15, respectively.
  • a charging rod 16 of a charging device is arranged, which extends parallel to the longitudinal direction of the electrically conductive roller 11 and interacts with it in the manner of a capacitor in order to electrostatically charge the material web 10 after it has reached the area of the Application device for the dampening solution has left.
  • the charging rod 16 is connected to a high voltage source U and the electrically conductive roller 11 to ground.
  • the spraying device 13 has a multiplicity of turntables 17 which are arranged next to one another in a row parallel to the first roller 14. As shown in FIG. 4, the turntables 17 are attached to a preferably lower end of a drive shaft 18 and have a central pot area 19, which is adjoined by a flat spray flange 20 which extends radially outwards. To drive the turntable 17 their respective drive shafts 18 are connected to a motor 21 in a suitable manner, not shown in detail.
  • an aperture 22 is arranged between the turntables 17 arranged in series and the first roller 14 of the application device 12, which has a passage opening 23 in the area of each turntable 17 for spraying onto the first roller 14 Has dampening solution.
  • the turntable with the assigned aperture areas form individual sectors, which are advantageously individually controllable, so that different sections of the material web can be rewet in the desired manner depending on the requirements.
  • the first roller 14 is provided with a water-friendly, that is to say well wettable, surface.
  • Suitable materials for the surface of the first roller 14 are e.g. Glass, ceramics and chrome.
  • chromium is preferably used because the roller 14 must be designed for very high speeds.
  • a pneumatic cylinder arrangement 26 or another suitable pressing force generating device acts on the bracket arrangement 24.
  • the material of the rubber roller (15) has a Shore hardness of 30 ° to 70 ° Shore, in particular about 50 ° Shore.
  • the force F is then chosen so that a surface contact pressure of about 0.9 to 2.5 dN / cm 2 , in particular 1.7 dN / cm 2 results.
  • the charging bar 16 of the charging device which extends parallel to the conductive roller 11, has, as shown in FIG. 5, a plurality of needle electrodes 27 which are arranged in a row at a distance from one another.
  • the needle electrodes 27 are preferably aligned in the radial direction to the roller 11 and thus perpendicular to the material web plane or to the tangential plane to the material web.
  • a constant temperature dampening solution for example water or water mixed with surfactants or other chemical substances, is supplied to the pot area 19 of the turntable 17 of the application device 13.
  • a high speed for example at 5000 rpm. with a turntable diameter of approximately 80 mm.
  • dampening solution droplets become or aerosols with a diameter of about 50 microns to 75 microns, preferably from 60 microns to 65 microns, flung from the edge of the turntable.
  • the device described for rewetting a printed paper web in web offset printing can be used in a particularly advantageous manner.
  • a continuous paper web is drawn off from supply rolls at very high speeds, for example at speeds in the range of 5-8 m / s, and printed in four consecutive printing units in four-color printing, for example. Then the printed paper web is in a drying station at temperatures dried at approx. 200 ° C to solidify the printing inks so that they can no longer be damaged in the subsequent processing. The drying process is then followed by cooling of the printed paper web, which serves to quench the heated and dried printing inks.
  • the paper web is also dried out, so that it only has a low residual moisture of approx. 3-5% after drying.
  • the paper web is relatively brittle, so that it is difficult to process in the subsequent operations, such as folding, cutting and stapling, and tends to be damaged.
  • uncontrolled changes in the dimensions of the paper web being processed occur when the paper absorbs moisture from the environment after the final processing operations. This leads to poor quality or unattractive printed products.
  • the device for moistening a moving material web described with reference to FIG. 1 can be arranged in a cooling station of a web offset printing press.
  • application devices 12 for applying dampening solution are arranged on at least one or preferably on two or more cooling rollers 11 of a cooling station of the printing press, of which only the first four cooling rollers 11 of, for example, a total of eight cooling rollers are shown.
  • two applicators 12 for dampening solution are assigned to these two cooling rollers, each of which brings about an opposite deflection of the paper web 10, so that both surfaces of the paper web 10 are moistened one after the other.
  • the application devices 12 are therefore preferably arranged on the inlet-side cooling rollers 11 in order to achieve rewetting of the paper web as soon as possible after drying.
  • the first application device can e.g. be arranged on the second cooling roller 11, as shown in dashed lines in FIG. 2.
  • the arrangement of the application devices 12 on the input side enables the use of a constant temperature dampening solution, which has a lower temperature than the paper web in this area, e.g. 15 ° C, additional cooling of the printed paper web.
  • 12 spreader rollers 28 can subsequently be provided on an application device, as shown in broken lines in FIG. 2, in order to avoid shrinking of the paper web in the transverse direction.
  • a major advantage of the device described is that it can be easily converted into a device Finished cooling station can be installed, the cooling rollers 11 being used as conductive rollers, which interact with the respective charging bar 16 and the second roller 15 of the roller arrangement.
