Hit embellished flat component and process for its manufacture

The invention relates to a flat component provided with decorations, in particular tile, the is characterized in that it consists of relatively thin sheet-shaped metal (foil or thin sheet metal), which is embossed with a desired one recessed and / or raised file having decorative shape is given. The thin, relief-like deformed metal, hereinafter referred to as metal foil, can be fitted with a Overlay made of a filler material that ensures the dimensional stability of the relief-like decoration

In an advantageous embodiment, the filler material is a thermoplastic material.

There are already decorated flat components or tiles made of ceramic material,

Plastics etc. known. Ceramic tiles are light Fragile and plastic tiles are despite the efforts of their manufacturers to imitate Kerasaik tiles, not very appealing "

From the known tiles-like components provided with decorations, the components of the invention differ in that the front side is metallic «? ₍ teas gives them a novel appearance that <äi @ s <s front side consists of thin sheet-shaped metal of any kind and is embossed in the desired way, whereby the small wall thickness of the metal9 is compensated by a cover attached to its back side.

Metal existing components should have a grain at their sunk points, is first in a two-stage process between the form and the Metal foil a sheet provided with an abrasive material with its grained side of the metal foil inserted opposite and the one made of the metal foil, the sheet provided with abrasive material and the mold and pressed thereon in the existing unit second stage after removing the sheet provided with abrasive material and after aligning the In this way, parts of the metal foil grained relatively SU the corresponding parts of the shape of the metal foil, the shape and the layer of deformable Material submerged one more time

The invention also relates to a method of manufacture of the molds used for the production of the components according to the invention, which consists in that on a rigid, flat base to which parts forming a relief-like pattern are attached «

Examples of the invention are given below by way of example

From Figure 1 it can be seen that the new product in the form of a with a metallic front provided flat decorated components consists of a deformed sheet or foil 1 of metal, a suitable filler material 2, for example © in thermoplastic material, is attached to its rear side that on the one hand prevents a change in shape of the deformed film caused by pressure and on the other hand serves to give the component such a thickness that it is, for example can be fixed in its intended position by gluing.

In order to produce one or more components of the type indicated above, it is, as Figure 2 shows, from a prepared in any Veise mold 3, and applies this to the later, the front face of the component forming metal foil 1, and on this a plate M- made of felt or similar material.

Then they become more superimposed! Parts 1, 3 » 4 subjected to strong compression, for example by running them between the rollers of a roller press (rollers A and B of FIG. 3) leaves, the metal foil being pressed against the mold 3 during the pressing process and deformed in relief.

The same reference numerals as in FIG. 2 are used in FIG. In this case it is assumed that the component to be produced should be provided with a relief-like geometric decoration, so that a form designated here by 13 is used, which consists of a flat rigid plate 13a on which individual molded parts 13b are attached, for example by gluing.

If one uses a form of the in Figure 3 i

wants to produce a component provided with a metal foil, the recessed areas of which have a grain, you work in two stages

In the first stage one works in the manner shown in FIG. 4, using an abrasive provided sheet 5 between the mold 13 and the metal foil 1, the rear side of which is supported on a rigid plate 6, and this structure between the smooth rollers A and B of a roller press go through IXBt. The grain size of the sheet 5 is

During the second stage shown in Figure 6, the sheet 5 is removed and IMBt, after the areas of the metal foil 1 provided with a grain with the corresponding areas of the mold realigned h & t, the vom 13 and slide 1, between the and the plate 6 a felt intermediate layer 4- has been introduced "again through the face
