Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for pasting gold leaf, and more specifically to a method for pasting gold leaf within an inscription on a tombstone or the like.

When a close relative dies, we hold a funeral to send the deceased away, and erect a tombstone at the place where the deceased was buried to express our respect and gratitude for the deceased. Naturally, the size of the tombstone must be limited by income and budget at the time, and as a result, the scale is often extremely unsatisfactory.In such cases, more magnificent tombstones may be erected in later years. There are many times when we wish to be straightened out, but in our society there is an unwritten law that forbids the rebuilding of gravestones once erected. As a way to splendid tombstones without violating the law, it is becoming common practice to attach gold leaf to the inscriptions (engraved characters) on tombstones.

This method of pasting gold leaf, which has started recently, involves applying an adhesive such as lacquer to the inside of the monument, then moistening the tip of the brush with the worker's saliva or by blowing on it to apply the gold leaf. It is something that is attached, carried to the attachment position, and attached. Gold is the most malleable of all metals, and the thickness of gold leaf is at least 1/10.
It is extremely thin and fragile as it can reach up to 1,000 mm in thickness, but in the conventional method, the gold leaf was attached to the tip of the brush using the adsorption power of water, so it was easy to wrinkle the gold leaf when it was applied. As a result, the wrinkles remained even after pasting, resulting in an unsightly appearance. Also, this gold leaf is usually 10cm long.
It is commercially available in a square size and lined with extinguishing paper,
In the past, it was difficult to cut this gold leaf, so instead of cutting it in advance to match the shape of the area to be pasted, the gold leaf was simply applied to the brush, carried to the area to be pasted, and the remaining part was removed with the brush. Since the gold leaf was cut into strips and pasted on adjacent places, there was a lot of loss of gold leaf, and considering that gold leaf is an expensive material, this loss was difficult to ignore. Furthermore, since the gold leaf is not cut in advance and is cut into strips with a brush and pasted according to the shape of the paste, the surface of the gold leaf has to be rubbed many times with the brush, and as a result, particles on the surface of the gold leaf are It was destroyed and lost all of its original luster, and the finished product was no more than a coat of gold powder, and was not aesthetically pleasing. Furthermore, since the entire process is carried out with a single brush, the adhesive tends to stick to the tip of the brush, which can damage the gold leaf and cause loss, which should be avoided. This meant that I had to stock up on a large number of brushes and replace them frequently, making the process tedious and inefficient.

The present invention has been made by focusing on the above-mentioned drawbacks of the prior art, and aims to provide a gold leaf pasting method that reduces loss of gold leaf, provides a beautiful finish, and improves work efficiency.

According to the present invention, the gold leaf is cut in advance using a fine ceramic cutter according to the shape of the area to be pasted, an adhesive is applied to the area to be pasted, and the attraction force generated by frictional electricity (static electricity) is applied. This is achieved by a gold leaf pasting method that consists of the steps of guiding a cut piece of gold leaf to the place to be pasted and setting it in place, pressing it lightly with a feather brush, and then shaping it with a brush.

The present invention will be described in detail below with reference to the accompanying drawings.

The gold foil pasting method according to the present invention consists of the following steps.

B. Cleaning Process First, prior to the pasting work, as shown in FIG. 1, the tombstone 1 to which the gold leaf is to be pasted is sufficiently cleaned to completely remove dust, sludge, etc. from within the inscription. If the tombstone is lightweight, it can be removed from the stand and carried indoors for work; however, if it is heavy and difficult to remove, it should be shielded with a tent, etc. to prevent it from being affected by outside winds, and be protected from dust during work. Make sure that it does not stick to the adhesive application area.

B. Cutting process of gold leaf pieces Gold leaf is usually commercially available in 10 cm square pieces lined with extinguishing paper, and there are various types depending on the thickness such as one and a half sheets, three sheets, four sheets, etc., but the present invention In the case of such an adhesion method, it is optimal to use about three sheets.

As shown in FIG. 1, the gold leaf 10 and the stamped paper 11 are cut into strips 14 using a fine ceramic cutter 12 in accordance with the width, depth, etc. of the engraved characters constituting the inscription.
Cut into pieces. Gold leaf is extremely thin, reaching a minimum thickness of 1/10,000 mm, so if you use a regular metal cutter, frictional electricity will occur and the gold leaf will cling to the cutter, making it difficult to work with. If it is a type of material, frictional electricity will not be generated and the work will be easy.

C. Adhesive Application Step Subsequently, as shown in FIG. 2, adhesive 15 is applied to the bottom and wall surfaces of the grooves of the engraved characters using a lacquer brush 16. Conventionally, lacquer and the like have been often used as adhesives, but the inventors have discovered that extremely good results can be obtained by using synthetic resin paints. Such synthetic resin paints include "Cashew Resin Paint" (registered trademark, manufactured by Cashew Co., Ltd.)
This paint is suitable for use with cashew thinner.
(registered trademark, manufactured by the same company) is used by appropriately mixing it. As far as the inventor has tested, the mixing ratio is preferably about 97 parts of paint: 3 parts of thinner when the ambient temperature is O'C, and when the ambient temperature is 25°C, almost all thinner is mixed. It was unnecessary.

This adhesive has extremely strong adhesion, so after stirring thoroughly with a lacquer brush, it is imprinted onto the bottom and wall surfaces of the groove. In that case, it is desirable to apply the gold leaf as thinly as possible because if it is applied thickly, it will dry and shrink and cause wrinkles in the attached gold leaf pieces later on.

Regarding drying, as far as the inventor's experiments have been carried out, the ambient temperature 2
In the case of 5°C, if the adhesive is allowed to dry for about 15 to 30 minutes after application, it is possible to proceed to the next step of pasting, but if the adhesive is allowed to dry further than that, there is a tendency for the degree of adhesion to deteriorate.

2. Following the pasting process, the process moves on to the step of pasting the pre-cut strip 14 to the adhesive application location, but in the case of the method according to the present invention, the strip 14 is moved and guided to the adhesive application location. As a means, a special gripping tool as shown in FIGS. 3 and 4 is used.

FIG. 3 is a plan view thereof, and FIG. 4 is a side view thereof. This gripping tool 20 has a roughly compass shape, and has a main body 22, a feather brush section 24 attached to one end of the main body, and a feather brush section 24 attached to the other end. It consists of a gripping part 26°26. The main body 22 is bifurcated near the center, and grips 26, 26 are attached to the tips of each branch. A stopper 28 is fitted near this branch point. As for the material of the main body 20, if you use a material that does not easily generate frictional electricity (static electricity) in the charging order and has excellent shape recovery properties, such as bamboo, it will eliminate the frictional electricity even if it comes into contact with the worker's body, clothes, etc. It is convenient because there is no need to wake up the foil pieces and attract them. The degree and size of triboelectricity are relative and differ depending on the materials that are rubbing against each other, but the materials that are in contact with each other include the worker's clothes, the worker's hands, and moisture such as sweat on the surface. Therefore, the main body 20 is made of a material such as bamboo, which generates almost no triboelectricity or generates only a small amount of triboelectricity even if it rubs against them in the electrification order. Furthermore, since bamboo material has excellent recovery properties, by moving the stopper 28 from side to side in FIG. It is convenient and possible. The material of this stopper 28 is also a material that does not easily generate frictional electricity, such as cotton thread or water-based material. On the other hand, the gripping parts 26 attached to both ends of the branch branches are made of a material that is likely to generate frictional electricity, that is, a material that seems to have a strong electrostatic adsorption force, for example, a material that is likely to generate frictional electricity, for example, as will be described later. When using a dry cloth as a friction material, it is convenient to use cut pieces of fishing line. As shown in FIG. 7, if this grip part has a circular cross section, the contact area will be small when the gold leaf piece is sucked, and therefore it will be easy to remove, which is convenient. The feather brush is made of feathers.

The method according to the invention uses such a gripper as a means for transporting the cut gold leaf strips to the attachment position.
When pasting, as shown in FIG.
The friction material 30 rubs the gripping portion of the grip to generate frictional electricity. As a result, as shown in FIG. 6, when the gripping portion 26 is brought close to the gold foil strip 14, the gold foil strip 14 leaves the foil stamping paper 11 and is attracted to the gripping portion, so that it can be held as is as shown in FIG. Then, carry it to the adhesive application area and press it lightly to set it in place. Gold leaf is attached not only to the bottom of the character groove but also to the walls on both sides, so adhesive is applied over the entire surface and the strips are attached (Figure 11).
. The friction material 30 may be made of any material, such as dry cotton cloth, as long as it generates frictional electricity when it rubs against the gripping portion 26.

Subsequently, as shown in FIG. 9, the feather brush part 2 of the gripping tool is
4, press the strip 14 from above to adhere it. As mentioned above, Gold No. N is extremely thin and the surface particles are fragile, so if you press it with a brush as in the traditional method, the surface particles will be damaged and scraped off, losing all of its original luster. However, in the case of the present invention, a feather brush that is much softer than a brush is used, and there is no process of pasting and tearing as in the past, and the shape of the pasting position is determined in advance. Because all you have to do is stick the strips cut to match the foil, the brush comes into contact with the foil much less frequently, which reduces the chance of damaging the surface particles and reducing the chance of losing the luster of the gold. This is extremely rare.

E. Finishing process Next, as shown in FIG. 10, the brush 40 is used to brush off the foil pieces from areas where the gold leaf strips 14 are pasted overlappingly, and remove the strips from the narrow areas at the corners of the letters. The gold powder that has been brushed off is applied to areas that are difficult to apply, and the overall shape is adjusted so that there are no areas where gold leaf is not attached. In this way, when finishing, the gold leaf (gold powder) is collected by brushing it off with a brush and used in narrow areas, and if there is still any leftover, it can be stored separately, so there is no loss in that respect. There are few. or,
The areas in which the brush is brought into contact are limited to the areas where the gold leaf pieces are polymerized and the narrow areas, and the brush is not brought into contact with other areas where the gold leaf is affixed, so compared to the conventional method, The area that the brush comes in contact with is greatly reduced, and the degree of damage to the surface of the gold leaf is also greatly reduced.

Through the above steps, finally, as shown in Fig. 11,
It is completed by pasting gold leaf 1o on the adhesive 15 all over the bottom and both sides of the groove of the engraved characters on the tombstone 1, and after completion, it can be left as it is and allowed to air dry. It's good.

As described above, in the pasting method of the present invention, gold foil is cut in advance according to the shape of the engraved characters, and the cut pieces are transported to the pasting position using a gripping tool that utilizes the suction force generated by frictional electricity. , it is constructed by pressing with a feather brush and adjusting with a brush. As a result, compared to conventional methods, there is less loss of gold leaf, and the final result is a beautiful and well-presented finish that fully takes advantage of the original luster.

Furthermore, it has the advantage that working time is shortened and working efficiency is significantly improved.
