Definitions

  • the present invention relates to a partial method Coating a paper web with pressure sensitive masses according to the preamble of claim 1 and a device for performing of the procedure.
  • the CH-PS shows 602 351 a coating process in which a color former and a dye acceptor composition which reacts with color formation can be applied to a paper web.
  • These masses are applied by means of flexographic printing units. This is from a container in which the mass to be applied is removed by means of an immersion roller and via a transfer roller on the ones carrying the printing formes Transfer cylinder.
  • the Mass released onto a paper web by an impression cylinder is supported.
  • color image masses are used which, for example, in organic solvents such as toluene or a Mixture of toluene and ethyl alcohol are dissolved.
  • EP-A-0 064 204 also describes a manufacturing process of carbonless reaction papers described using flexographic printing. Also here coating compositions are used, the organic solvents include and thus also have the disadvantages mentioned above.
  • An object of the invention is to provide a partial method Coating a paper web with at least one pressure-sensitive, to create usable mass for copying, in which the to be applied Mass can be dosed exactly, this mass is environmentally friendly should be.
  • forms from two Paper webs are produced which have previously been printed in a known manner become.
  • the one paper web is then partially and at the back with the first, mass containing dye-forming components coated, while the the second paper web is partially coated on the front with the second mass, contains the ingredients that the dye-forming components in dye convert.
  • the two paper webs are then placed on top of each other, so that the two coated areas come to lie on top of each other, can then be put together and cut.
  • This method can also be used, for example, in an advantageous manner
  • Forms are made that are formed from a paper web that have been printed accordingly beforehand.
  • the mentioned two masses so partially on one surface of the paper web applied that when zigzag folding this paper web with the corresponding mass-provided areas come to lie on one another, and can then be cut.
  • This method can also be used, for example, for a paper web be coated with a mass containing both dye-forming components as well as contains components that contain the dye-forming components convert to dye.
  • a paper web that is also printed has been partially coated on the front.
  • another paper web can be placed, with the formation the two sheets of paper are joined and cut from forms can be.
  • the coated paper web can also be zigzag folded provided and then cut.

  • a material is advantageously chosen for the printing forms, which has a good wetting, so that the raster image of the mass, that of the Anilox roller is transferred to the printing forms, before being applied to the Paper web dissolves essentially automatically. This will put on the paper web get an optimal mass layer, which results in good quality of the typeface when copying.
  • the paper web partially coated in this way is after the coating process passed through a drying plant.

It would also be conceivable that the paper web directly from the printing machine, not shown, of the coating system 3 is supplied.
  • the paper web 2 is between one Impression cylinder 4 and an impression cylinder 5, which are turned against each other are passed through.
  • the printing cylinder 5 is, as will be described in more detail later is provided with printing forms.
  • the impression cylinder 5 and in particular the printing forms are in contact with an anilox roller 6.
  • This anilox roller 6 dips into a container 7 in which the coating composition 8 is included.
  • the coating composition 8 is driven by the anilox roller 6 is picked up and scraped off with a squeegee 11 positioned negatively, that the mass 8 is only in the cups of the grid Anilox roller 6 is located. This mass is then on the printing forms of the Transfer printing cylinder 5 from where the order is placed on the paper web 2.
  • the peripheral speed of the anilox roller 6 is essentially correct with the peripheral speed of the impression cylinder 5. It is but also conceivable that the peripheral speed of the anilox roller 6 with respect that of the printing cylinder 5 can be reduced slightly, whereby the amount of mass applied to the surface of the paper web 2 is reduced can be, this reduction is at most in the range of about 5 percent of the applied coating mass.
  • the coating composition 8 in the container 7 is in a known manner constantly circulated.
  • air bubbles can form which are attached to the Surface of the coating compound 8 arrive.
  • the container 7 is designed that the coating compound 8 can flow over a side wall, this overflowed mass is on an inclined plane in a known manner fed back into a storage container. While going through the the air bubbles come to the surface and burst, the air trapped inside can escape.
  • the paper web 2 is covered by a Drying system 9 performed, in which the partially applied layers be dried. Then the paper web 2 is shown schematically System 10 fed for further processing. Further processing can consist of the creation of forms, as described below , but it is also possible that the paper web is wound on a roll which is then, for example, another coating system is applied to apply a further layer.
  • FIG. 2 shows a first paper web 12 and a second paper web 13 can be seen, the assembled and cut to form a form 14 become.
  • the two paper webs 12 and 13 are in a coating system, as described for Fig. 1, coated.
  • the first Paper web 12 has been partially coated with a first mass, which contains dye-forming components.
  • the partial layers 15 were applied to the back 16 of the first paper web 12.
  • the first paper web 12 and the second paper web 13 are so placed on top of each other that layer 15 comes to lie on layer 18. Then the two merged paper webs 12 and 13 in be cut in a known manner, whereby the form 14 is formed. This form 14 can be copied in the area of layers 15 and 18.
  • Fig. 3 is the production of a form 19 with a paper web 20 shown.
  • On the surface 21 of the paper web are in two coating steps each with a system as shown in Fig. 1, one Layer 21 of the first mass and a layer 22 of the second mass applied been.
  • the first mass contains dye-forming components
  • the second mass contains constituents that form the dye Convert components to dye.
  • the paper web 20 is then folded that the layer 21 of the first mass on the layer 22 of the second mass comes to rest. This can be achieved, for example, by a zigzag fold become. However, other types of folding are also conceivable, for example one Longitudinal folding.
  • the paper web 20 can then be cut so that Forms 19 are created. These forms 19 can also in the area of Layers 21, 22 are written through.
