Definitions

  • the invention relates to an inking device for the ap ⁇ plication of colouring matter to a printing pad which moves past the point at which the colouring matter is applied, and which is thereafter brought into contact with the surface of the article to be coloured.
  • Hitherto known inking devices of this kind are usual- ly designed as a part of the actual printing pad, which is normally supplied with liquid colouring mat ⁇ ter via a tube.
  • the colouring matter is contained in an inner reservoir in the printing pad itself.
  • the object of the invention is to overcome the dis ⁇ advantages of the known inking devices, and this is achieved when the inking device comprises one or more baths filled with liquid colouring matter, the bottom of said baths being provided with a slot for the del ⁇ ivery of colouring matter, and a cylindrical roller which can rotate around its longitudinal axis and lie up against said slot.
  • the bath By forming the bath as a concave part which can more or less lie up against the inking roller, as presen ⁇ ted in claim 2, a suitable distribution of the col ⁇ ouring matter can take place which, particularly with colouring matter having a high viscosity, results in a very even application and distribution of colouring matter on the roller.
  • the distance between the bath and the roller is expedient, as presented in claim 3, for the distance between the bath and the roller to be capable of being varied, in that this provides the possibility of dosing the application of colour ⁇ ing matter.
  • fig. 1 shows a sectional view of a printing device comprising an inking device and a rotatable printing pad
  • fig. 2 illustrates the actual printing shown in in three phases
  • fig. 3 shows the inking device seen in perspec ⁇ tive
  • fig. 4 shows a sectional view hereof seen in the direction IV-IV in fig. 3.
  • the printing method itself is illustrated in figs. 1 and 2.
  • the printing pad 5 is formed as a part of the revolving cylinder which turns around its axis of ro ⁇ tation 6. This rotation is effected by means of co - monly-known turning arrangements (not shown) .
  • an ink ⁇ ing device 1 This comprises a freely-mounted roller 3 which can turn around its longitudinal axis.
  • the roller is supplied with colouring matter when it turns past a slot in the bottom of the bath 2 which is mounted above the roller.
  • colouring matter is supplied to the surf ⁇ ace of the roller when the roller is turned, which occurs when the printing pad moves in under the roller, thus creating mutual contact between said pad and said roller, from the position shown by con- tunuous lines in fig. 1 to the position shown by stippled lines to the right of the roller.
  • the print- ing pad is then turned back again, whereby the roller is once more made to rotate, but now in the opposite direction.
  • the printing pad swings down to the posi ⁇ tion shown by the dot-and-dash lines, where the one edge of the printing pad makes contact with the sur- face of the article 7 to which colouring matter is to be applied.
  • the actual printing is illustrated in fig. 2.
  • the article 7 lies firmly while the axis of rota ⁇ tion 6 of the printing pad is moved towards the left - to the position shown by stippled lines, with the printing pad resting on its opposite edge, in that it
  • the actual inking device is shown in figs. 3 and 4. It comprises one or more baths 2 , each provided with an inner reservoir for liquid colouring matter 4. In the bottom of the baths there is a narrow slot 9. This slot can be some millimetres wide and can extend in length to whatever degree demanded by the inking of the roller.
  • the bottom of the baths is cylindrical in shape, so that the inking roller can turn under the slot 9, see particularly fig. 4, whereby a suitable layer of col- ouring matter is applied to its surface.
  • the distance between the concave bottom surface of the bath and the roller can, moreover, be varied, thus allowing the thickness of the layer of colouring matter to be adjusted.
  • a number of baths are placed in a row, whereby printing with several colours side by side can be effected.
  • the printing pad 5 can make contact with the roller during its movement in the one direction only, in that the inking device can be lifted and lowered, hereby providing the pos- sibility of printing with very thin layers of col ⁇ ouring matter.
  • the inking device is particularly suitable for the printing of acryl plates, where one can thus imitate coloured glass by applying colouring matter of the desired colours in fields.

Abstract

Afin d'appliquer une substance colorante (4) sur un coussinet imprimant pouvant déposer la substance colorante là où l'on désire effectuer l'impression, il est nécessaire d'utiliser un dispositif encreur se composant d'un ou de plusieurs bains (2), chaque bain possédant une fente de distribution (9) de la substance colorante et présentant une forme concave analogue à celle d'un cylindre avec un diamètre correspondant à un rouleau (3) pouvant tourner librement autour de son axe longitudinal. Il est ainsi possible d'appliquer la substance colorante sur la surface, et la quantité de substance colorante est déterminée par la distance entre le rouleau et le coussinet imprimant, cette distance étant réglable. En permettant au coussinet imprimant de passer tout en étant en contact avec le rouleau, celui-ci tourne et la substance colorante est déposée sur le coussinet imprimant. On applique de la sorte une couche mince et uniforme de substance colorante sur le coussinet imprimant, ce qui permet d'exécuter l'impression avec une quantité réduite, inconnue à ce jour, de substance colorante. Ceci est particulièrement avantageux lorsqu'on applique la substance colorante par exemple sur des plaques acryliques, comme décoration.
