Definitions
- the invention relates to a method and an embossing tool for the production of embossed signs, in particular motor vehicle license plates, where one, if necessary provided on one side with a reflective film Sheet metal, in particular aluminum sheet, by means of a Embossing tool consisting of several upper parts and lower parts to a shield with raised protrusions on one side of the shield Sections and intermediate deepened sections embossed and the raised sections using on the visible side of the shield a colored plastic film can be made colored.
- signs in particular Motor vehicle license plates
- the letter and / or Combination of numbers also called legend
- the raised is embossed Legend and possibly also the edge colored.
- the legend of the white Shield colored black is done e.g. according to DE 37 41 232 C2 using a so-called hot stamping plastic film.
- the Plastic film as a carrier material for a heat-removable Colour.
- the embossed sign is placed on a work table or put a conveyor belt so that the visible side is directed upwards.
- the invention is therefore based on the object of a method and also a tool for making embossed Signs, in particular motor vehicle license plates, of the type mentioned at the beginning to show which the manufacture of the finished sign with a enable as little work and energy as possible.
- a stamping tool for carrying out the method is according to the invention characterized in that the upper and lower parts of the embossing tool each other facing first working areas for embossing the raised sections of the Schildes and facing each other, second working areas for embossing the have recessed portions of the shield and that a mutual distance of the first work area areas with the embossing tool closed at the end of the Embossing process is smaller than a mutual distance between the second Worktop areas.
- the basic idea of the invention is therefore a plastic film to use one-sided with a pressure sensitive Glue is provided, and this film together with the board, which may already have a pre-made, can have an embossed and colored edge (cf. DE 40 40 386 C1) in the embossing tool. While of embossing, in the upper and lower part of the Embossing tool are pressed onto the board and the raised sections are formed also the plastic film in the area of the raised sections under correspondingly high pressure on them Sections pressed. Because of this high pressure the pressure sensitive adhesive is glued, i.e. made adhesive.
- the adhesive effect of the adhesive is now either depending on the type of plastic film used the colored plastic film itself or a color layer applied on one side to the film which is the adhesive layer on the raised Sections glued.
- the embossing tool should be designed in this way be that the plastic film on the border between the raised sections and the recessed sections severed and after opening the embossing tool the rest of the black plastic film like a grid can be deducted. In the latter case, the slide not severed.
- a colored one e.g. black, plastic film used a pressure sensitive adhesive layer on one side Has adhesive.
- a plastic film could also be used the one side with a removable paint layer is, the layer of paint on the plastic film facing away from an adhesive layer of pressure sensitive Has adhesive.
- the embossing tool consists of several upper parts 1 and several assigned sub-parts 2. For each character, i.e. every letter or number is for making of a motor vehicle license plate own upper part and a lower part provided.
- the upper part 1 has a recess 3 corresponding to the Contour of the character to be embossed.
- the lower part 2 has a projection corresponding to the character to be embossed 4 on.
- the depression in the upper part 1 is appropriate surrounded by an edge 5 projecting towards the lower part, which corresponds exactly to the contour of the recess 3.
- This protruding edge 5 can advantageously in a cut edge leak as shown in the drawing.
- the Work surface 6 of the upper part 1, which is the recessed Sections 21 of the embossed plate 20 corresponds (see FIG. 2), is opposite the edge 5 of the lower part 2 staggered away. This means that the protruding edge 5 in relation to the work surface 6 protrudes an amount a of, for example, 0.3 mm.
- the depth t of the recess 3 compared to the above Edge 5 is e.g. 1.7 mm.
- the height h can be approximately 2-3 mm be.
- 20 denotes a flat board, e.g. consists of aluminum sheet. Possibly However, this board could also be made of sheet steel or Plastic.
- this board on your Visible side 20a coated with a reflective film 23 be.
- the board 20 can not with one shown prefabricated edge to be provided has already been colored.
- the coloring can according to DE 40 40 386 C1 even before attaching the reflective film 23 take place.
- Above the visible side 20a of the circuit board 20 ' also becomes a plastic film 24 arranged on its underside facing the visible side from the film manufacturer with an adhesive layer 25 is made of pressure sensitive adhesive.
- the glue is designed in such a way that it can only be used when high pressure becomes sticky and its adhesive effect unfolded.
- the recessed area 21 of the Shield 20 an adhesive of the film on the visible side 20a of the shield 20 or to the reflective film 23.
- the upper part 1 and the lower part 2 are made to register.
- Edge 5 becomes the plastic film 24 at the transition between the raised section 22 and the recessed section Section 21 severed.
- Upper part 1 and lower part 2 must be coordinated so that during the stamping process only stain the colored plastic film 24 is cut through.
- the underlying reflective Foil 23 must not be damaged so that the surface so affected that the exam according to DIN 74069 no longer exists. After opening of the embossing tool you can use the remaining black plastic film 24 pull off like a grid. Then remain nor the unembossed sections 21 and the legend that through those glued to the raised portions 22 black plastic film becomes visible.
- a plastic film that is one-sided with a Color layer, e.g. a black layer of paint is.
- the color layer is then on the plastic film opposite side with an adhesive layer made of pressure sensitive adhesive, coated.
- the plastic film only serves as a carrier film for the color layer.
- the shield does not stick, so that one after opening the embossing tool, pull off the carrier film can. Then only those detach from the carrier film Sections of the color layer in the area of the raised Sections 22 adhered to them by the high pressure were.
