Description

The invention relates to a method for designing a tire, in particular for applying a pattern, image or graphics on the tire, wherein a cover material is applied to a surface of the tire and permanently attached to the surface, ie a method according to the preamble of patent claim 1 and a device kit according to the preamble of the independent device claim.

In tires, whether solid rubber tires or pneumatic tires, it is expedient to apply markings, in particular to a side surface of the tire. A mark can serve to make a tire z. B. as a summer or winter tires to mark. Markings are z. For example, only single characters or dashes; The simplest way of marking is probably in a car repair shop quickly when changing tires with any pen applied mark, so as not to confuse the individual tires with each other. However, it is also possible to apply more or less elaborate design elements, such as color-emphasized shapes or images, on the tire, in particular in order to make the tire graphic. The side surface of the tire comprises a relatively large area, which can be customized by a service-providing workshop or an end user, without the risk of paint damage or scratches on discs. This allows an end user to customize his vehicle, be it a car, a tractor, an agricultural machine or a two-wheeler. The tires can z. B. in the color or the color pattern of the paint of the body of the vehicle are designed. In many cases, the shaping of the tire is done by fixing prefabricated picture elements to the tire surface, or by patterning the tire surface, particularly during the manufacturing process of the tire.

The DE 10 2011 050 704 A1 describes a pneumatic vehicle tire on which four different characteristics in the form of elevations, depressions or vulcanized rubber parts are applied.

The US 2011/0079332 A1 describes a tire on which flexible PVC stickers are glued.

The object is to provide a method or a device kit, with which a tire can be designed in a simple manner graphically or at least in color, in particular by anyone by means of an easily manageable method or kit.

This object is achieved by a method according to claim 1 or by a device kit according to the independent device claim. Advantageous developments of the invention are explained in the subclaims. In this case, the features of the embodiments described below can be associated with each other and realized together, unless this is explicitly denied.

A method for designing a tire, in particular for applying a pattern, image or graphic to the tire, preferably to a tire made of an elastic material, in particular rubber, especially on a side surface of the tire, comprises applying a covering material to a surface of the tire Tire and a permanent attachment of the cover material to the surface, in particular a permanent adhesion.

According to the invention, it is proposed that a template is applied to the tire and the cover material, in particular a chalk, is applied in the region of the template. In other words, the tire is at least partially covered in the region of the template with the covering material, in particular a chalk. As a result, the surface can be designed in a simple manner, in particular by persons who are not practiced therein, or have "two left hands".

Under cover material is to be understood as a material which is set to cover the tire surface so strong that it does not shine, z. B. any opaque and on the tire surface, in particular rubber, adhering substance of a particular color, or a chalk, especially chalk fat. Optionally, liquid rubber can also be used as the cover material.

Preferably, the tire surface is cleaned and dried prior to application of the cover material, e.g. B. by means of a sponge.

• a) Abziehen einer Bodenfolie der Schablone, insbesondere von einer Schablonenfolie der Schablone;
• b) Aufkleben einer Unterseite der Schablonenfolie auf die Reifenoberfläche, insbesondere unter Vermeidung von Blasenbildung, wobei bevorzugt auch ein Glätten bzw. Anpassen der Kontur der Schablonenfolie an die Reifenoberfläche erfolgt;
• c) Abziehen einer Deckfolie von der Oberseite der Schablonenfolie;
• d) Bedecken der von der Schablonenfolie nicht abgedeckten Bereiche der Reifenoberfläche mit Deckmaterial, insbesondere Ausmalen der von der Schablonenfolie nicht abgedeckten Bereiche der Reifenoberfläche.

According to one embodiment, the tire may be configured by the following method steps:

• a) peeling off a bottom foil of the template, in particular of a template foil of the template;
• b) adhering an underside of the stencil film to the tire surface, in particular while avoiding the formation of bubbles, whereby preferably also a smoothing or adaptation of the contour of the stencil film to the tire surface takes place;
• c) removing a cover sheet from the top of the stencil sheet;
• d) covering the areas of the tire surface not covered by the stencil film with cover material, in particular coloring the areas of the tire surface which are not covered by the stencil film.

According to an advantageous embodiment, a self-adhesive stencil film of the template is glued to the tire for attaching the template. As a result, the template can be easily fixed in a desired position.

At least one pattern or at least one recess is preferably introduced in the stencil film. The stencil film has at least one pattern or at least one recess. As a result, a design of the tire surface can be made strictly in accordance with a predetermined contour.

Preferably, the template or at least the stencil sheet is ring-segment-shaped or disc-segment-shaped, that is, like a sub-segment of a ring or a disc. As a result, the stencil sheet can be applied over a large area of the side surface, and it can, for. B. also a lettering on the side surface are applied, which extends over a large circle segment of the side surface, z. B. over 90 °, or even over 180 °, or in particular cases over more than 270 °, in particular 360 °. According to a variant, the stencil or at least the stencil sheet is annular or disk-shaped, thus extending over 360 °.

According to an advantageous embodiment, which may be based on one of the embodiments described above, first of all a bottom foil of the stencil is removed from the stencil and then a template foil (s) is applied to the tire, in particular a side face of the tire, and then a cover foil of the template Remove the stencil from the stencil sheet, and then, after covering with cover stock, remove the stencil sheet from the tire. As a result, a template having a plurality of recesses or patterns can be applied to the tire surface without warping, wrinkles or creases.

Preferably, a time to dry the chalk is maintained, preferably about 10 to 20 minutes, more preferably 12 to 17 minutes, especially about 15 minutes, before the stencil sheet is removed from the tire surface. As a result, the opacity and the strength or adhesive force of the cover material can be increased.

The stencil film and the tire surface are preferably wiped with a sponge before removal or removal of the stencil film, in particular in order to remove loose residues of cover material, in particular chalk, from the tire surface and the stencil film.

According to an advantageous embodiment, which may be based on one of the previously described embodiments, the tire is covered with a covering material in the form of an air-drying chalk, in particular chalk. This can be done with a robust, inexpensive, non-hazardous material design of the tire. It has been shown that the chalk in conjunction with the template enables a particularly simple handling. A particular advantage is that the chalk can be used as a cover material which does not flow between the tire surface and the stencil, but only adheres to the tire surface which is not covered by the stencil, ie in the area of the recesses. As a result, even very fine patterns or characters can be applied, in particular by means of a sharpened chalk. The chalk or fat chalk consists preferably of soft wax compounds, each with desired color pigmentation (color addition). The fatty chalk has z. For example, the following admixtures: waxes about 10-25%, titanium (IV) oxide about 10-25%, barium sulfate about 2.5-10%. A chalk (ie, a wax crayon, so no special chalk) has z. For example, the following admixtures are present: talcum 10-15%, titanium (IV) oxide about 0-5%, barium sulfate about 2.5-10%.

The chalk, in particular chalk, can be sharpened or shaped like a pencil before application, in particular in order to work more accurately and / or to be able to exert a relatively high pressure on the tire surface.

Preferably, the chalk is applied in several layers, in particular in at least two or three layers. Advantageously, in each case a time for drying the chalk is maintained between the application of individual layers, preferably about 10 to 20 minutes, more preferably 12 to 17 minutes, in particular about 15 minutes. It has been found that at such a time for drying, the durability of the cover layer can be significantly improved, so that the cover layer remains adhered to the tire surface for a longer time. Also, this can be maximized the opacity of the chalk, so that even chalk material can be saved. The design of the tire becomes clearer, higher in contrast, which leads to clearer patterns or motifs, especially in the case of several colors. This makes the patterns even more appealing. Preferably, three layers are applied. It has been shown that three layers have a satisfactory, sufficient hiding power result. More than three layers are possible, but not essential. Preferably, the chalk is applied by directed movements, in particular by brushing the chalk in a (in particular a single) predetermined direction. As a result, a uniform degree of coverage and a smooth surface can be achieved. If the tire surface has grooves, the chalk is preferably spread over the tire surface in the direction of the grooves.

According to an advantageous embodiment, which may be based on one of the previously described embodiments, a stencil sheet (s) of the stencil is smoothed before a cover sheet (s) of the stencil is removed from the stencil sheet. This can ensure that a pattern can be applied particularly accurately. The stencil sheet can be fixed with good adhesion to the tire surface, and there are no gaps or protruding edges.

According to a variant of the tire can also be designed by a prefabricated design element. The prefabricated design element may be affixed to the tire by the following method, in particular a method of designing a tire, in particular for applying a pattern, image or graphic to the tire, preferably a tire made of an elastic material, in particular rubber, especially one Side surface of the tire, wherein the design element, in particular a color remote from the tire pixel is mounted on the tire, wherein the design element on its underside (corresponding to a contact surface to the tire) by means of a hairy spatulae with Härachchen with the surface of the tire in contact is brought. Preferably, the underside is adapted to exert van der Waals forces on the surface of the tire.

As mentioned above, the aforementioned object is also achieved by a device kit according to the independent device claim, namely a device kit for designing a tire, in particular for applying a pattern, image or graphic to the tire, preferably a tire made of an elastic Material, especially rubber, especially on a side surface of the tire, it being provided according to the invention that the device kit has a template which is formed by three superimposed films.

As a device kit is preferably a tool or kit to understand, which includes a part of all or all the essential components or components that are required for carrying out the method according to the invention.

According to an advantageous embodiment, the template has a bottom foil and / or a self-adhesive stencil foil and / or a cover foil. As a result, the template can be applied in a simple manner and smoothed.

The stencil film preferably has an adhesive underside and a smooth, non-adhesive top side. More preferably, the top is made of a polyethylene-based material. More preferably, the film is transparent. The surface can be finely grained. The stencil film is flexible and very tear-resistant.

According to an advantageous embodiment, which may be based on one of the previously described exemplary embodiments, the stencil film has an adhesive on its underside, that is to say on the side of the bottom film. As a result, the stencil film can be fixed in a desired position.

According to an advantageous embodiment, which may be based on one of the above-described embodiments, the adhesive is a modified polyacrylate-based pressure-sensitive adhesive which has a low adhesive setting, i. H. Adhesive force, preferably less than 1 N / 25 mm. As a result, the stencil sheet can be easily removed from the tire again. It has been found that an adhesive force of less than 1 N / 25 mm is sufficient, and that this force is not so high that there is a risk of tearing the stencil film when the stencils are to be removed again. The adhesive force is preferably a force which is necessary to remove an adhesive strip, in particular a 25 mm wide adhesive strip. The adhesive setting is preferably a mixture of the adhesive, which leads to the desired adhesive force.

According to an advantageous embodiment, which may be based on one of the embodiments described above, the device kit comprises a smoothing plate and / or a cover pin, in particular a fat chalk, and / or a sponge. With this, all method steps for applying the template and the pattern can be carried out. The device kit is very inexpensive and easy to handle. In this case, a commercial cleaning sponge may be used, in particular with a lower side made of sponge material (preferably 100% polyurethane), and an upper side made of nonwoven material (preferably 10% polyamide, 10% polyester, 20% binder, 60% abrasive grain) ,

As a smoothing plate is to be understood a plate-shaped, substantially planar element, which is adapted for smoothing the stencil sheet, z. B. a sliding triangle or smooth triangle, so a substantially flat part in the manner of a spatula or ice scraper.

Preferably, the screed plate is at least to some degree elastically deformable and adapted to conform to the contour of a side surface of the tire. More preferably, the screed plate has a side with a concave geometry, wherein the radius of curvature of the side preferably corresponds to the corresponding radius of curvature of the side surface of the tire. Particularly preferably, the smoothing plate has several sides, each with a concave geometry, each with a different radius of curvature, so that the smoothing plate can be used for different tire contours.

Preferably, the cover sheet is transparent and / or the stencil sheet gray and / or the bottom sheet white. In this color distinction, a user can be easily instructed, and the method can be performed with good security without errors, especially without prior knowledge.

According to a variant of the tire can also be designed by a prefabricated design element. The prefabricated design element can be attached to the tire by means of the following device kit, in particular a device kit for designing a tire, in particular for applying a pattern, image or graphic to the tire, preferably a tire made of an elastic material, in particular Rubber, especially on a side surface of the tire, wherein the device kit comprises a design element, in particular a color remote from the tire pixel on the tire.
