Definitions

  • the invention relates to a process for the production of ceramic tiles with a stripe decor, in particular an only approximately regular stripe decor, wherein molded tiles are pressed from the mass taken in portions at the mouth of a funnel, and the stripe decor is produced by strip-like laying out of material containing dye, and the molded tiles are added to the tile be burned.
  • the invention relates to a device for performing the method, in which a compression mold is fed by a filling slide fed from a funnel.
  • Such a method and such a device are known from use.
  • the dye-containing material is sprinkled there on the already pressed tile molding and spread further by washing with water.
  • the invention is based, a method and a task To create device by means of which unglazed tiles with a stripe decor and in particular with an only approximately regular, ie subject to natural modifications, stripe decor can be produced.
  • this purpose is achieved in that stripes of different colors are placed in strips alongside one another in the form of a flat band and the band is poured continuously, still in the form of a band and forming a gable-shaped cluster, into the funnel.
  • a device according to the invention for realizing this procedure is characterized in that the hopper is preceded by a conveyor belt parallel to the direction of movement of the filling slide and at least two feed hoppers, which at least partially open out side by side on the conveyor belt, the discharge end of which is arranged above the hopper.
  • the stripe shape of the mass is translated by the gable-shaped accumulation and, as it turns out, even more precisely in the funnel into the shape of vertical layers.
  • the filling slide allows these layers to exist with their movement parallel to them and transfers them into the press mold. As far as the layers discard and mix something in all of this, this is intended as a natural, changing variation. You get a stripe decor that continues similar to natural stone through the depth of the tile. The decor is absolutely wear-resistant. The tile does not need to be glazed. Nevertheless, it can.
  • a base mass is laid as a tape and a stripe or a plurality of stripes, preferably at a distance from one another, of a mass containing dye is or are placed.
  • a feed hopper or a plurality of feed hoppers for dye-containing material preferably with a lateral spacing from one another, opens out or open out behind a feed hopper for a base material.
  • the uncovered base mass and the mass containing dye placed over it are then streaked alongside one another in stripes on the conveyor belt.
  • the dye-containing mass mixes with the base mass on which it was lying, but only along the fall line and thus forms a vertical layer. This occurs only or predominantly on the flank of the mass continuing in the top view and not at all or hardly on the flank of the gable-shaped accumulation which extends back under the band.
  • the vertical layer of the dye-containing mass does not extend from one funnel wall to the other at the mouth of the funnel, this is achieved by the transfer into the filling slide and the transfer to the mold, both of which are from one side to the other progressive, balanced. With this procedure, striations that look particularly natural stone are obtained.
  • the strip or strips placed on the tape of the base material offers the possibility of changing the position of the strip or strips, and also the spacing of the strips from one another, very simply, and thus the To make stripe decor even more changing and more natural.
  • the feed hopper for the dye-containing mass can be moved back and forth with its orifices in the transverse direction, preferably also against one another, and can be provided with a drive therefor.
  • the invention allows very precise stripes to be produced.
  • the funnel will be rectangular in its horizontal cross sections.
  • the funnel is expediently approximately trapezoidal in its vertical cuts parallel to the conveying direction of the conveyor belt, and the trapezoidal legs further away from the compression mold are slanted than the other, preferably approximately vertical, trapezoidal legs.
  • a press 1 of conventional design has three molds 3 as recesses in a press table 2. Into this square presses closing their square cross section can be lowered. The bottom of the molds 3 is formed in the same way by lower punches which close the square cross section and which are raised after the pressing process in order to eject the tile moldings upwards. The press stamps and the lower stamps cannot be seen in the drawing.
  • the mass is fed to the molds 3 in a manner known per se from a hopper 4 by means of a filling slide 5.
  • a filling slide 5 In this there are continuous recesses 6 of the same cross-section and in the same arrangement as the molds 3 from top to bottom. With their height, they have the volume provided for filling the molds with the mass.
  • the recesses 6 lie below the funnel, the lower edge of which lies closely around the surface of the filling slide.
  • the recesses are closed at the bottom by tightly resting the filling slide 5 on a floor. With the mass thus received in the recesses under the funnel, the filling slide slides on the floor into its front end position. In this, the recesses are above the molds, so that they empty into them.
  • the filling slide When sliding forward, the filling slide also pushes the tile moldings 7 previously ejected from the lower punches onto a roller bench 8.
  • the mouth of the funnel 4 is particularly adapted to the recesses of the filling slide in the present case.
  • the funnel is branched, for example in the lower third or quarter, into three, again funnel-shaped, outlets, which in the rear end position of the filling slide each comprise one of the recesses 6. So that the mass flow in the lower region of the funnel and when filling the recesses 6 is more uniform than without dividing the mouth.
  • the funnel 4 is also significantly smaller than the funnels previously used at this point. It no longer has a supply or intermediate supply function and, apart from filling the filling slides, only serves to control the mass flow.
  • the mass is fed to the hopper 4 in the form of a belt 9 by means of a conveyor belt 10.
  • the belt 9 is produced on this belt by first laying a continuous belt 12 of a basic mass from a feed hopper 11 and then four from four further feed hoppers 13 Strips 14 of dye-containing mass are placed.
  • the dye-containing mass of the strips 14 mixes with the basic mass of the band 12, but only along the fall line and thus forms a vertical layer approximately the width of the strip 14. This occurs only or predominantly on the flank 16 which continues the band of mass in plan view and not or hardly at all on the flank 17 which extends back under the band 9.
  • vertical funnel wall 18 does not extend to the other, oblique funnel wall 19, this is compensated for by the transfer into the recesses 6 of the filling slide 5 and the transfer into the mold 3, both of which proceed progressively from one side to the other . In the mold 3, the layer finally extends fairly continuously. Certain variations are no harm here either, but are usually desired.
  • the conveyor belt 10 is pivoted very slowly back and forth about an axis located near the mouths of the feed funnels 11 and 13.
  • the vertical layers resulting from the strips 14 finally shift alternately more to one or the other side in the molds 3; the two middle layers can also pass from the middle mold 3 to one of the side molds 3.
  • the mass of the strips 14 can contain the same or different dye. It can be tinted based on marble colors or other natural stones.
