Description

Technical field

The utility model relates to a method for attaching signs to a surface, in particular metal signs, letters, numbers on the exterior surfaces of monuments, monuments, in particular stone monuments, monuments. The subject of the utility model is also an aid for carrying out said method, which substantially speeds up and streamlines the affixing of the marks, while at the same time completely reducing the risk of errors and inaccuracies in describing monuments, memorials and similar objects.

BACKGROUND OF THE INVENTION

In the stone industry, the production of monuments has been known for several centuries the way of punching letters into a stone plate. The punched grooves are colored in a durable color, inlaid with Friday gold or otherwise differentiated from the substrate. These historical ways of describing are poorly productive, dating back to a time when the value of human labor was insignificant. Nowadays, there are few skilled stone-cutters who are able to cut out signs, letters, numbers into the stone.

In order to increase productivity, features which are attached by means of pins extending from the back of the feature (e.g. according to DE7805205U1) have been used. The characters have a thickness in the order of millimeters and are usually metal, which gives them good durability. Drilling, respectively. milling holes in a stone plate is faster than punching out the entire feature, but requires precise placement and spacing of the pin holes. For this purpose, special purpose milling cutters are used (eg according to SK UV 5358). Various templates for drilling holes in stone slabs (eg according to FR2770385A1) are also known, but do not provide substantial acceleration and ease of work.

It is also known to affix interior panels and labels when various adhesives and adhesive tapes are used. Accurate results are not achieved when attaching individually placed characters, and gluing is lengthy as each character is glued separately.

It is not known, and a feature-fastening solution is required which is simple and quick to use, requires no apparatus and equipment, and provides durable results.

The essence of the technical solution

The aforementioned drawbacks are substantially eliminated by the method of attaching characters to a surface, where separate characters are spaced apart from each other by a gap, and wherein the characters, with their back side, touch the surface according to the present invention. the double-sided adhesive tape is initially affixed to the back of the feature, and the double-sided adhesive tape is provided on the opposite side with a temporary covering layer on the adhesive which is removed prior to affixing the feature to the surface.

The same principle of adhesive bonding is retained in the process where the adhesive is applied to the back of the characters not by means of double-sided adhesive tape, but is sprayed using a computer-controlled nozzle and subsequently covered with a temporary covering layer which is removed at the attachment point.

This method will be particularly useful, but not exclusively, for metallic features. Under the feature, it is necessary to imagine any substantially flat bodies forming the desired text, marking, in mutual association. It will be mainly letters, numbers, which are attached to the exterior surfaces of monuments, memorials, especially stone monuments, memorials, boards. They may also be pictograms, characters, picture frames, pictures and the like.

It will be appreciated that the double-sided adhesive tape is cut or the adhesive is applied such that the width of the adhesive is less than the respective width of the feature. In this way, the edge of the double-sided adhesive tape, respectively. hides the glue from sight and at the same time reduces the influence of UV radiation on the edge of double-sided adhesive tape in exterior. The difference between the tape width and the corresponding feature width can be from 0.2 mm up to 3 mm, or up to 20% of the feature width. This measure also simplifies the bonding of the double-sided adhesive tape to the back of the feature, when minor inaccuracies in position do not cause the tape to protrude over the edge of the feature.

Although the surfaces will be primarily straight and smooth and the metal features also have a straight back side, it will be advantageous for the glue, respectively. the double-sided adhesive tape had a thickness of at least 0.2, preferably more than 0.4 mm. In the solution of this disclosure, a larger adhesive thickness is used not to overcome the unevenness but to compensate for the different thermal expansion. In a thicker layer of adhesive with shear stresses and deformations, a different change in the dimensions of the metal sign compared to the stone

SK 6653 Υ1 substrate. During long-term exposure to outdoor conditions, thermal changes are repeated, which, with a normal, thin adhesive tape (usually up to 0.15 mm), could eventually cause the emblem to fall off the substrate. In view of the long-term stability, it is suitable that the adhesive, respectively. the base of the double-sided adhesive tape was an acrylic, pressure-activated adhesive. The method of affixing the features described is characterized by simple application without the need for drilling or milling of holes.

The character attachment productivity is further enhanced if a template according to the present invention is used, where first the holes are formed in the template for the individual characters in the desired grouping and spacing, the characters already adhered with double-sided adhesive tape are inserted into the holes and then the grouping of characters together the template is applied to the area where the characters are pasted using double-sided tape with the temporary covering layer removed. If the adhesive is applied to the back of the characters through a nozzle, not in the form of a double-sided adhesive tape, it will be appropriate for the adhesive to be applied to the characters only after they have been inserted into the template. If the adhesive is applied through a nozzle, the waste that results from cutting the double-sided adhesive tape into the desired shape of the back side of the features is saved.

It is advantageous if the template is used not only for attaching the characters, but also for distributing the characters to the stonemason, respectively. to the business, the person who will attach the characters to the desktop. The thickness of the template should be the same as the thickness of the characters. should be thinner than the thickness of the characters with the applied adhesive, respectively. with double-sided adhesive tape applied. However, the thickness of the template should not be less than a third of the thickness of the characters to hold the characters well in the template. The openings in the template should not be significantly larger than the respective dimension of the feature, so that the position of the feature is clearly determined.

The template may be made of paper, cardboard, microwave board and the like. The feature holes can then be easily cut with a cutting plotter or laser. The template will usually be one-time, and can be used repeatedly in case of repeated matching texts and labels.

The stonemason orders the entire text at the head office, such as first name, year of birth, year of death, epitaph with the selected character type, font. First they cut a template in the headquarters. The opening of the holes is governed by a computer design in which the character spacing, inter-character spacing, inter-row spacing, alignment and the like can be appropriately set.

The manual character counting and the design made by the stonemason directly on the desktop are transferred to the central office, where they are first executed on the computer, allowing editing and reviewing the relevant views. Subsequently, holes are cut into the template using computer control and the worker inserts the appropriate characters into the holes. At this stage, an error is ruled out, since only the corresponding feature can be inserted into the holes and the absence of the feature in the hole is easily noticeable. Characters with pre-glued double-sided tape are inserted into the template. From the point of view of simple logistics, all characters of the given type and font are prepared in stock and the worker chooses from them when inserting into the template.

The stonemason receives the ordered characters from the central office so that they are already inserted in the template. The template thus also facilitates transportation, the characters are transported in sheets that provide protection against damage, the characters are not abraded during transportation. Signs can be easily transported by mail to the stonemason.

When attaching the stonemason cleans the area, he can controlly place the template with the characters on the area and mark the correct place of the edge of the template. It then removes the temporary backing on the adhesive from the back of the characters and places the template with the characters on the surface. Characters press on the surface, which can be done by hand or roller. The stonemason removes the template and the characters remain attached to the desktop.

The surface cleaning step may also include degreasing with a degreasing agent which is allowed to act on the surface. To increase the resulting bond strength, the process may also include the step of increasing the adhesion by means of an adhesive which the stonemason applies to the surface after cleaning and degreasing. The procedure described above significantly increases character attachment productivity and eliminates incorrect or crooked character attachment.

In a preferred embodiment, after insertion into the template, the characters may still be glued on the front side with an adhesive film, preferably a transparent adhesive film, so that the feature set is still visible in the template. It may also be an ordinary translucent adhesive tape, it should have less adhesive force than the double-sided adhesive tape, so that the adhesive film can be easily torn off after the features have been attached to the surface. The adhesive film keeps the markings in the holes of the template, even if the transport is rough, the markings are not released.

Removing the temporary covering from the double-sided adhesive tape from the individual features can be slow for several features, and therefore a method has been devised in which the adhesive film is also applied to the back side of the stencil where it adheres to the temporary covering of the double-sided adhesive tape. When removing the adhesive film from the back of the stencil, all the individually formed strips of the temporary covering layer are torn off at once, thereby quickly preparing the features for attachment.

The process of this invention provides not only accurate and equal character attachment, but also high productivity when the successive character attachment is replaced by the mass attachment of the character group in the template. At the same time, the stripping of the individual strips of the temporary covering layer is quick and convenient. The procedure is applicable when attaching to a stone panel in a horizontal position in the workshop, but also when attaching characters to an already existing monument. This also benefits the quick and simple attachment

EN 6653 ovania1. Stonemason can work on the finished monument to help liners, spirit level, which determines the line of the template.

The shortcomings described in the prior art are also solved by a new device for attaching signs to a surface, in particular metal signs, letters, numbers on the exterior surfaces of monuments, memorials, especially stone monuments, memorials according to this technical solution. The apertures, dimensions and shape of the apertures in the template correspond to the features in the desired grouping and the features are provided on the back with an adhesive with a temporary coating, preferably a double-sided adhesive tape with a temporary coating.

It will be advantageous if the width of the double-sided adhesive tape is smaller than the respective width of the feature. The difference between the tape width and the corresponding feature width can be from 0.2 mm up to 3 mm or up to 20% of the feature width. For reasons stated in the description of the process, it will also be advantageous for the double-sided adhesive tape to have a thickness of at least 0.2, preferably more than 0.4 mm. In order to achieve a high durability of attachment, it is desirable that the base of the double-sided adhesive tape be formed by an acrylic pressure-activated adhesive.

The thickness of the template should be the same as the thickness of the characters. should be thinner than the thickness of the characters with double-sided tape applied. However, the thickness of the template should not be less than a third of the thickness of the characters to hold them well in the template. The openings in the template should not be significantly larger than the respective dimension of the feature, so that the position of the feature is clearly determined.

The template may be made of paper, cardboard, microwave board and the like. The template will usually be one-time. The template may also contain an identification code, e.g. The stonemason's order number so that it can be easily handled at the template headquarters and excluded from delivery.

The performance of the device is enhanced by an arrangement where the features are pasted on the front side with an adhesive film, preferably a transparent adhesive film, for example a translucent adhesive tape. In order to accelerate the tearing off of the temporary covering layer from the double-sided adhesive tape, the device may be provided with an adhesive film from the back. The aid of this description will be delivered to the stonemason, who will use it to attach the characters to the desktop. The stonemason can see and check on the device how the lettering will look when the characters are attached to the desktop.

The method and the device according to the present invention can also be used for interior inscriptions and markings, where a fast fastening by means of a template is used in particular. The signs may be affixed to walls, furniture, doors and the like.

EXAMPLES

Example 1

In this example of Figures 1 to 9 and 15 to 15, the method of attaching characters 1 is used to create inscriptions on a stone monument. The stonemason agrees with the client on the exact wording of all the inscriptions on the monument, as well as on the type of letters. The agreed text and font will be written in the order at the head office. At the headquarters, the agreed wording is spread out on the computer, the text is divided into lines, aligned and the screen preview is checked. The laser cutter is then controlled by the computer, which cuts openings in the microwave board sheet to form a template 2. In this example, a five-layer microwave board of about 4.5 mm thickness is used. The thickness of the cast metal marks 1 is about 4.5 mm. The openings have the shape of the corresponding characters 1 of the selected font type.

At the headquarters there are 1 different types of markings available, ready for dispatch with a finished surface, already having double-sided adhesive tape 3 applied on the back. This is carved into the shape of the corresponding feature 1, the width of the cut double-sided tape 3 is approximately 1 mm smaller than the width of the metal body of feature 1 at the appropriate location. The 0.6 mm double-sided adhesive tape 3 is applied to the characters 1 before accepting the order and is provided with a temporary covering layer 4 which protects the adhesive until it is fixed. The double-sided adhesive tape 3 has an acrylic adhesive base, is carved centrally from strips or sheets, and subsequently the cut-outs are applied to the back of the features 1 and put into storage.

In the example, each line is captured in one template 2, that is, the entire label is divided into several templates 2 so that they can be easily transported by mail.

After all the characters 1 have been inserted into the templates 2, a transparent adhesive tape which forms the adhesive film 5 is adhered to the front side, and the same adhesive tape is adhered to the back side of the template 2 where it forms the adhesive film 6.

Adhesive tape ensures that the characters 1 from the template 2 do not appear to remain fixed in the template 2 during transport and the surface finish of the characters is not damaged L Since the adhesive tape used is transparent, both the worker and the stonemason have a quick visual check for completeness and correctness At the same time, the adhesive film 5 on the front holds the characters 1 in the template 2 when placing it on the surface 7, the stonemason no longer needs to insert and retain the characters 1 in the template 2 when placing it on the surface 7.

Templates 2 with embedded ordered characters 1 are sent to the stonemason from the central office. He checks them, thoroughly cleans the area 7 on the stone slab of the monument and measures the position of the inscriptions. The cleaning step in this example also includes degreasing. The stonemason applies a continuous layer of degreasing agent to the surface 7 by means of a sprayer and is allowed to act for approximately 30 seconds. Then wipe the surface dry with a soft cloth. Repeat the same degreasing step again.

The degreaser will apply an adhesive to the degreased surface with a new clean cloth, which will increase the adhesion of the features 1 to the surface 7. The stonemason will apply a thin continuous film of adhesive to the surface 7, this step does not repeat.

So far, the stonemason places the text on the prepared surface 7 without gluing, i.e. without torn off the temporary covering layer, and marks the appropriate placement of the text on the monument. It then removes the adhesive film 6 from the first template 2 at the back of the template 2, at the same time tearing off the temporary covering layer 4 from the double-sided adhesive tape 3. The characters 1 are not removed from the template 2. Now the stonemason will precisely place template 2 with all the embedded characters 1 on the surface 2 and press the characters 1 against the surface 7. This procedure repeats the stonemason with the other templates 2, making it not sticky on characters 1 but sticking the name, surname and other character groups L After removing the temporary covering layer 4, characters 1 must be applied immediately. The stonemason presses the characters 1 by hand (possibly with a pressure roller) together with the template 2, trying to achieve a thrust force of at least 10 N / cm ² - thereby fixing the characters 1 firmly.

After sticking the characters 1, the stonemason also pulls off the adhesive film 5 on the front of the template 2 and removes the template 2 from the surface 2 ·

Full, 100% adhesion is achieved after about 72 hours. During this time it is not recommended to force the sticking of i. This results in a high quality rigid joint that is also flexible. The workflow should be continuous, without breaks.

Example 2

In this example of Figures 1, 4, 5, 10 to 15, the adhesive is applied to the back of the characters 1 only after the characters 1 have been inserted into the template 2. The template 2 is cut out at the headquarters according to the customer's order. that creates banners in the hotel. Stencils 2 are cut from cardboard and marked with numbers for better orientation.

In the central unit, the characters 1 are inserted into the template 2 and subsequently attached from the front by an adhesive film 5. The template 2 with the characters 1 is then placed on the work table with the back side up. Computer - controlled nozzle

SK 6653 Υ1 carries the adhesive to the back of the characters L After applying the adhesive to all the characters 1 of one template 2, the adhesive layer is covered with a temporary covering layer 4 which covers the entire back side of the template 2.

Thus, in this arrangement, the temporary cover layer 4 also functions as an adhesive film 6. The temporary cover layer 4 can be easily torn off as it is integral. The plates with the templates 2 are conveyed to a hotel where, in a similar manner to Example 1, the characters 1 are attached to the designated locations. This creates inscriptions such as “Reception” or room numbers on the door, with individual characters 1 being separate and accurately attached.

Example 3

According to Figure 16, templates 2 are used which have a marker for centering the inscription. In this example, the tag is a notch on the outer edge of template 2.

If several templates 2 are used in one row, it is sufficient if the tag has a template 2 having a central position. The presence of the mark helps the stonemason, but does not prevent him from scheduling the placement of the inscriptions at any time, depending on the particular need, which is also affected by the placement of the cross or other element on the monument.

Figure 17 shows the procedure for later completion of the date of death on an already mounted monument, where a linear line is attached using suction cups and a template 2 with L characters is attached. Precise attachment can also be achieved without the linear line, according to the indicated line.

Industrial usability

Industrial applicability is obvious. According to this technical solution, it is possible to industrially and repeatedly use a method and aids for durable and fast attachment of the signs, especially to the area of monuments and other stone surfaces.
