Description

The present invention relates to a coating roll, a manufacturing method thereof, and a paint roller provided with the coating roll.

Conventionally, a paint roller for applying a coating material such as paint, which is used for painting an outer wall of a building, is generally intended to apply the coating material uniformly (Patent Document 1).
The paint roller includes a handle and a shaft rod formed integrally with the handle, and is used by attaching a cylindrical coating roll in which a brush or the like is planted to the shaft rod.

Patent Document 1 includes a roller, a roller frame that rotatably supports the roller, and a handle attached to the roller frame, and the outer surface of the surface is divided into a number of portions on the surface of the roller. There is provided a sinking tool for a coating floor material for making the coating thickness of a coating floor material constant, characterized in that partitioning partitions are arranged and a number of dents are formed by the partition wall and the surface. A plurality of indentations regularly shown in FIG. 1 to FIG. 3 are shown, and the plurality of indentations are independent and not continuous.
According to Patent Document 1, a seamless resin floor is constructed by a sink method using a coating floor material made of a liquid reaction-curable composition by using the above-described sink coating tool for a coating floor material. In this case, it is said that the coating layer can be flowed so that the coating thickness is substantially uniform and the surface is horizontal without requiring skill.

On the other hand, in recent years, in order to enhance the decorativeness of the outer wall of the building, an irregular pattern is applied to the outer wall of the building. The irregular pattern can be formed by applying a uniform undercoat with the paint roller, and then applying a different color of paint to the undercoat by tilting the roll so that it does not cover the entire undercoat. It was done by making the best use of it.
In recent years, various ideas for the coating roll have been proposed so that even non-skilled craftsmen can quickly apply the uneven coating material (Patent Documents 2 to 5).

Patent Document 2 discloses a patterned coating tool having a coated surface made of a raised fabric, wherein the coated surface is formed from fibers containing wet heat-adhesive fibers at a ratio of 50% by mass or more on one side of the ground structure. The napped fiber layer has a plurality of irregular cell-like pores in which the fibers forming the napped fiber layer are opened outward from the napped fiber layer surface, thereby forming the napped fiber layer. It is formed from a napped fabric having a sponge-like napped fiber layer that is bonded to each other in a net-like manner at the napped fiber layer portion by the adhesive action of the wet heat-adhesive fiber in a state where a number of irregular patterns are formed on the surface of the fiber layer. A patterning paint tool is shown which is characterized in that (Claim 1, FIG. 1 and FIG. 2).
According to Patent Document 2, the napped fabric forming the coating surface of the coating tool has a sponge-like napped fiber layer having a concavo-convex pattern on at least a part of the ground structure. It is said that a pattern can be formed.

Patent Document 3 discloses a patterning roller characterized in that one end of each of a large number of elastic sheets formed in an appropriate shape is attached to the surface of a roller that is rotatably mounted. 1, FIG. 1 and FIG. 6).
According to Patent Document 3, with the above-described configuration, it is possible to easily construct complicated and repeated patterns without making full use of advanced technology.

Patent Document 4 has an outer layer composed of a foamed polymer material, has an outer diameter of 55 to 75 mm, and has a concavo-convex part with a flat convex part formed on the surface of the outer layer. The distance between them is 5.0 to 30 mm, the angle formed by the inclined portion of the concave portion and the convex portion in the concave and convex portion is 20 to 80 °, and the porosity of the outer layer is 70 to 90%. A coating roller is shown (claims 1 and 4).
According to Patent Document 4, even in the production of a painting such as an oil painting, when a paint of a different color is applied on a paint that has not been sufficiently dried after application, the paint that has already been applied and the paint that has been overcoated It is said that mixing colors can cause intermediate color development or spotted patterns.

Patent Document 5 includes a roller main body having a paint adhesion layer on the outer peripheral surface, and a cylindrical member that covers the roller main body, and the cylindrical member has a plurality of through holes in a peripheral wall thereof, A hole is formed in at least one end of the cylindrical member, and a coating roller is shown in which the paint adhesion layer protrudes from the through hole to form a brush portion. 2 and FIG. 3).
According to Patent Document 5, the coating roller adopting the above-described configuration is formed by simply covering the roller body with a cylindrical member having a plurality of through holes. It is the paint adhesion layer (brush part) of the roller body that protrudes from the through-hole, and it is assumed that the paint is not applied to the cylindrical member. Therefore, the material for forming the cylindrical member is not particularly limited, and the productivity is It is said that it is also possible to manufacture a cylindrical member by high injection molding, and further, since the patch pattern is formed by the brush portion protruding from the through hole, the number, size, shape, etc. of the through hole of the cylindrical member It is said that it is possible to clearly form various spot patterns with a high degree of freedom, and because it is possible to form different spot patterns simply by replacing cylindrical members with different through-hole shapes, it is also said to be highly versatile. Cylindrical Since it easily forms a large number of irregularities simply put the timber on the roller body, is also simple and easy assembly work.

JP-A-11-207245 JP 2005-288275 A Japanese Utility Model Publication No. 2-19572 Japanese Patent No. 5626671 Japanese Patent No. 5905632

The one disclosed in Patent Document 1 is intended to apply a uniform coating material as described above, and includes a plurality of dents, but the plurality of dents are regularly arranged, and an area between adjacent dents. That is, the convex portions are continuous and not separated into a plurality.

Patent Document 2 shows a coating roll having a plurality of irregularly arranged cellular pores, but the plurality of cellular pores are separated from each other on the surface of the napped fiber layer. The cell-like pores on the surface of the napped fiber layer are not provided, that is, the region between the adjacent cell-like pores is continuous.
For this reason, when painting a pattern with a color (second color) different from the color of the undercoat (first color) on the coating roll, the coating roll is applied to the coating surface in the same manner as the uniform undercoat. When rolled, the region colored with the second color becomes continuous, and it is difficult for the far eye to distinguish between the two colors of the first color and the second color and lacks interest. With such a coating roll, if you want to make a distinctive color scheme that can be distinguished from a wall painted in a single pattern even at a distance, you must rely on the advanced techniques of skilled craftsmen.

Also in Patent Document 3, there are some ideas such as attaching one end of a large number of elastic sheets to the roller surface. As shown in FIGS. 1 to 3, the flocked region of the elastic sheet and the elastic sheet are flocked. It is not clearly distinguishable from the non-flocked region, and even if the roller is simply rolled onto the painted surface, it is difficult to distinguish the two color schemes in the distant view and lacks interest. With such a coating roll, if you want to make a color scheme that can be distinguished from a wall painted in a patternless pattern even at a distance, you must rely on the advanced techniques of skilled craftsmen.

Further, in Patent Document 4, as shown in FIG. 4, in the unevenness of the outer layer composed of the foamed polymer material, the concave region and the convex region are not clearly divided into regions and have a gradation on the painted surface. Even if a paint pattern can be applied, it is difficult to distinguish the two color schemes at a distance and lacks interest. With such a coating roll, if you want to make a color scheme that can be distinguished from a wall painted in a patternless pattern even at a distance, you must rely on the advanced techniques of skilled craftsmen.

On the other hand, in Patent Document 5, an irregular pattern can be applied by covering an existing coating roller with a mask (cylindrical member) having holes (through holes) in some places. The non-adhered portions of the coating material having no coating are continuous, and clearly define the space between the adhering portions of the coating material from which the brush portion protrudes from the hole. Therefore, by forming the holes in an irregular shape and size, and by arranging the holes such as opening the gaps between adjacent holes, the difference in color between the undercoated area and the overcoated area can be Recognizable painting is thought to be as easy as undercoating.

However, in the technique disclosed in Patent Document 5, it is troublesome to attach a mask to the roll body in which the brush is implanted. Specifically, it is necessary to take the trouble of mounting a coating roll having the entire surface of the brush on the shaft of the paint roller and covering the coating roll with a cylindrical member formed separately from the coating roll. was there.
In addition, when the bristle portion of the brush portion is short, there is a case where it is difficult to form an intended finished pattern because the thickness of the mask is obstructed and sufficient coating material cannot be attached to the brush portion.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Basic configuration of paint roller)
The paint roller 1 includes a handle 2, a shaft portion 3, and a coating roll 4 (FIGS. 1 and 3). The shaft portion 3 is a metal bar, and includes a shaft 31 and an intermediate portion 32 that connects the shaft 31 and the handle 2. In this example, the intermediate portion 32 is bent, and the extending direction (longitudinal direction) of the shaft 31 is substantially perpendicular to the extending direction (longitudinal direction) of the handle 2.

The coating roll 4 is mounted on the shaft 31 of the shaft portion 3 via the roll fitting portion 5 (FIG. 3). The shaft 31 is a central axis of rotation of the coating roll 4.
Specifically, the cylindrical roll fitting portion 5 is fitted to the shaft 31 so as to be rotatable with respect to the shaft 31 (FIG. 3). In this example, end cap parts 51 having larger diameters than other parts of the cylindrical roll fitting part 5 are provided at both ends of the cylindrical roll fitting part 5. The end cap part 51 is a plastic member. The coating roll 4 is force-fitted to the end cap portion 51, and the coating roll 4 is pivotally supported together with the roll fitting portion 5 with respect to the shaft 31.

In this example, the end cap portion 51 is a lid that closes the openings at both ends of the cylindrical coating roll 4. However, the roll fitting portion 5 does not include the end cap portion 51, and for example, the entire outer peripheral surface of the roll fitting portion 5 can be directly brought into contact with the inner peripheral surface of the coating roll 4. That is, the roll fitting part 5 forcibly fits the coating roll 4 to the outer peripheral surface of the cylindrical body as a cylindrical body having an outer diameter corresponding to the inner diameter of the coating roll 4.

At the tip of the shaft 31, that is, at the end opposite to the intermediate portion 32 of the shaft 31, a stopper is formed so as not to drop the roll fitting portion 5 from the rotating shaft (not shown). For the retaining, a protrusion is provided on the outer peripheral surface of the distal end side of the shaft 31, the diameter of the distal end side is formed larger than other portions in the longitudinal direction of the shaft 31, or a flange-like member is screwed Well-known means such as doing can be adopted.

A coating material such as paint is attached to the outer peripheral surface of the coating roll 4 mounted on the shaft 31, and the coating roll 4 is rolled on the surface to be painted with the handle 2, that is, the coating surface, and the coating material is applied to the coating surface. be able to.
The coating roll 4 has a plurality of coating material adhesion portions 41 for mainly adhering the coating material to the outer peripheral surface, and recedes toward the center side of the painting roll 4 from the coating material adhesion portion 41 to apply the coating material to the coating material adhesion portion 41. And a coating material non-adhering portion 42 that is not adhered so much.
Hereinafter, the configuration of the coating roll 4 will be described in more detail.

(Painting roll 4)
The coating roll 4 includes a cylindrical roll body 40 and the coating material attaching part 41.
In this example, the roll body 40 includes a cylindrical core member 40 b and a covering portion 40 a that covers the entire outer peripheral surface of the core member 40. Specifically, a paper tube is employed for the core member 40b. A plastic cylindrical body can be adopted for the other core member 40b.
Further, a felt sheet in which a felt is stretched on the surface is adopted as the covering portion 40a. The felt sheet is attached to the outer peripheral surface of the core member 40b with an adhesive. As the adhesive, a known adhesive that can fix the covering portion 40a so as not to be separated from the surface of the core member 40b is adopted.
The roll body 40 can be implemented even if it does not include the covering portion 40a.

Each of the coating material adhering portions 41 is composed of a felt piece, that is, a felt sheet piece 41p (FIG. 2A). A plurality of coating material adhering portions 41 are formed on the surface of the roll body 40 by sticking the plurality of sheet pieces 41p to the surface of the covering portion 40a of the roll body 40 with an adhesive. As the adhesive, a well-known adhesive that can be attached so as not to separate the sheet piece 41p serving as the coating material attaching portion 41 to the surface of the covering portion 40a is employed.
Each of the sheet pieces 41p serving as the coating material attaching portion 41 is pasted on the surface of the covering portion 40a of the roll body 40 with a space therebetween, and the coating material attaching portions 41 are scattered on the outer peripheral surface of the roll body 40.

As described above, the coating material adhering portion 41 is made of felt, so that the surface of the coating material adhering portion 41 can be smooth without undulations. Further, the felt is well separated from the liquid coating material. For example, by adopting plastic for the core member 40b, the coating roll 4 can be repeatedly used by washing.
However, if the coating material adhering portion 41 is replaced with the felt, a pile fabric, that is, a velvet with a short bristle or a synthetic cotton such as velor, bettin, corduroy, polyester cotton, etc. is used. The above effects can be obtained. In particular, when the above-described polyester cotton, that is, cotton-like polyester is employed as the coating material adhering portion 41, it is preferably formed so as to have a thickness of about 5 mm with respect to the surface of the roll body 40. However, as long as the desired coating can be performed, the coating material adhering portion 41 made of polyester cotton may be formed to a thickness other than the above thickness.

The surface (felt) of the covering portion 40a exposed from between the plurality of coating material attaching portions 41 provided on the outer peripheral surface of the roll body 40 (covering portion 40a) in a state of being separated from each other becomes the coating material non-attaching portion 42. The coating material adhering portions 41 are scattered, that is, the coating material adhering portions 41 are spaced apart (dispersed). Each part of the coating material non-adhering portion 42 is assumed to be continuous and surrounds each of the coating material attaching portions 4. In this example, the coating material adhering portion 41 is also felt and the coating material non-adhering portion 42 is also felt, but the coating material non-adhering portion 42 is a coating material corresponding to the thickness of the coating material adhering portion 41 (sheet piece 41p). It is also a region that is recessed by the attachment portion 41 and recedes toward the center side of the roll main body 40, and the coating material is less likely to adhere than the coating material attachment portion 41.

The roll body 40 may not include the covering portion 40a, and the portion exposed from between the coating material attaching portions 41 of the core member 40b may be the coating material non-adhering portion 42. For example, in this example in which the core member 40b is a paper tube, the portion exposed from between the coating material adhering portions 41 on the surface of the paper tube is the coating material non-adhering portion. When the core member 40 b is a plastic cylindrical body, the plastic surface exposed from between the coating material adhering portions 41 becomes the coating material non-adhering portion 42.

The plurality of coating material adhering portions 41 are a mixture of two or more types or two or more types having different dimensions. Most preferably, all the coating material adhering portions 41 have different shapes or dimensions. Each of the coating material adhering portions 41 has a non-geometric shape that does not have a geometric outline such as a polygon or a circle. It is preferable that the outline of the coating material adhering portion 41 is formed by a non-geometric curve. However, it does not exclude the case where some straight lines or arcs are included in the curve. In addition, some coating material adhesion parts 41 may be provided with a geometric outline.
By providing the coating material adhering portion 41 (the unfolded sheet piece 41p) with a non-geometric contour as described above, a tasteful coating that does not result in an artificial inorganic impression on the wall surface without requiring skill. Can be applied.

Also, as described above, by using pile fabric with short hairs such as felt or velor or synthetic cotton such as polyester cotton for the coating material adhering portion 41 or the coating material non-adhering portion 42, the coating material adhering portion 41 or the coating material is used. The surface of the non-attachment part 42 can be made smooth without unevenness, and the coating material can be uniformly attached at the coating material attachment part 41. On the other hand, the coating material non-adhering portion 42 is uniformly retracted without protruding, so that partial coating material adhesion hardly occurs. Accordingly, the coating surface coated with the coating roll 4 by one rolling of the coating roll 4 is applied with a uniform coating material without any unevenness in the area in contact with the coating material adhesion portion 41. In the region facing the coating material non-adhering portion 42, unintentional adhesion of the coating material can be eliminated, and a sharp and easy-to-see color scheme with high contrast is possible.

In this example, the diameter (outer diameter) of the roll body 40 is preferably 1 cm or more and less than 5.5 cm, and particularly preferably 3.5 cm or more and 5 cm or less. And the protrusion width of the coating material adhesion part 41 with respect to the roll main body 40 surface, ie, the thickness of the sheet piece 41p, is preferably 0.5 mm or more and 5 mm or less, and particularly preferably 2 mm or more and 4 mm or less. The outer diameter of the roll body 40 of the coating roll 4 shown in FIGS. 1 to 3 is about 4 cm.
The length of the roll body 40 in the axial direction is preferably 10 cm to 30 cm, and particularly preferably 13 cm to 23 cm. In this example, the roll body 40 has an axial length of about 18 cm.
When the coating material adhering portion 41 is felt, the protrusion width is particularly preferably 0.5 mm or more and 4 mm or less. When the coating material adhering portion 41 is velvet, velor, bettin or corduroy, the protrusion width is 2 mm or more. Particularly preferably, it is 4 mm or less. When the coating material adhering portion 41 is made of polyester cotton, the protruding width is preferably not more than 8 mm, particularly preferably around 5 mm.
It is preferable that the coating material adhering portions 41 arranged in a dispersed manner are not less than 3 mm, and more preferably 5 mm or more apart, even between the closest parts.
As described above, the coating material non-adhering portions 42 are arranged between the coating material attaching portions 41 so as to surround each of the coating material attaching portions 41 and continuously separate the coating material attaching portions 41 from each other in an irregular stepping stone shape. It is considered as an area.

The total surface area of the plurality of coating material adhering portions 41 (sheet pieces 41p) is the same as the surface area of the coating material non-adhering portion 42 (exposed surface area of the core member 40b) or more than the surface area of the coating material non-adhering portion 42. Preferably, it should be small and not less than half of the surface area of the coating material non-adhered portion 42.
However, as long as the painted surface can be appropriately applied to a plurality of colors, the dimensions of each part of the coating roll 4 are not excluded even if they are out of the above dimension range.
The material of the coating material adhering portion 41 is not limited to the above, but as already described, piles such as velvet, velor, betting, corduroy, and felt have short hairs and a smooth surface and are not deformed. Therefore, the coating material adhering portion 41 can be clearly defined with respect to the coating material non-adhering portion 42. That is, in the coating material adhering portion 41 composed of the above-described material, the brush does not sleep even during use, and the portion holding the coating material is less likely to be deformed such as expansion and contraction. For this reason, the structure which separates the said coating material adhesion part 41 in a stepping stone shape by the coating material non-adhesion part 42 can be taken easily, and the coating performed using the said roll 4 for coating is sharp between many colors. It can be easily colored. Even at a distance, it can be recognized that the painted surface has been colored by multiple colors.
Even when the material of the coating material adhering portion 41 is a cotton-like chemical fiber such as polyester cotton, the same effect as described above can be obtained in the coating by adopting a material having a thickness of 5 mm or less or around 5 mm.

Moreover, each coating material adhesion part 41 is formed smaller, the protrusion width (thickness) of the coating material adhesion part 41 is made smaller, the interval between the coating material adhesion parts 41 is designed smaller, or the number of paintings In contrast to the above, the gradation effect can be enhanced by increasing the number of colors by increasing.

(How to use Paint Roller 1)
Here, a coating method using the paint roller 1 will be described.
First, painting is performed as a base base coating on a wall surface to be a coating surface t with a paint roller equipped with a general coating roll (not shown). By painting using this general painting roll, the painted surface exhibits a patternless single color (FIG. 8A). In addition, in the example shown in FIG. 8, the wall surface (siding board) provided with the unevenness | corrugation imitating the state which assembled the some block-shaped stone material is set as the coating surface t.
As the base coating, it is preferable to use a waterproof sealer (water-based hybrid sealer).

As described above, the coating roll 4 according to the present invention is fitted into the roll fitting portion 5 of the shaft portion 3 which is a constituent member of the paint roller 1 (FIGS. 3 and 1). Then, the handle 2 is grasped, and the painted surface (referred to as the base base t1) after the base base coating (refer to FIG. 8A and FIG. 10) has a color (first color) different from that of the base base t1. The coating roll 4 is immersed in a tray for storing the coating material, and the coating material is attached to the coating material attaching portion 41 of the coating roll 4 (not shown).

The paint roller 1 with the coating material attached to the coating roll 4 is rolled on the coating surface t, and the coating material attached to the coating material adhesion portion 41 is applied onto the non-patterned single color base base t1 ( FIG. 8 (B)). By the application, a first chromatic coating surface t2 covered with a coating material having a color different from that of the base base t1 can be formed on the coating surface t (FIG. 10). In the example shown in FIG. 8B, the first chromatic coating surface t2 is a surface where the dark first chromatic coloring is applied in some places on the light-colored base base t1.

As described above, the coating material adhering to the coating material adhering portion 41 is simply separated by the non-geometric plurality of coating material adhering portions 41, so that the coating roll 4 is simply applied on the coating surface even if it is not an expert. By simply rolling, it is possible to apply a coating that can feel the texture even between distant areas with sharpness between the adhesion area of the coating material and the non-adhesion area where the coating material is not adhered.

In this example, the first colored coating surface t2 is formed by rolling the coating roll 4 obliquely, that is, in a direction having a depression angle of 30 to 60 degrees with respect to the vertical direction (vertical direction) (FIG. 8 ( B)). In particular, coating is performed by rolling the coating roll 4 in a direction having a depression angle of about 45 degrees with respect to the vertical direction. This is because the vertical direction or horizontal direction in which the stone-like unevenness extends does not match the painting direction, thereby producing a more natural texture that is not artificial.
However, the present invention is not limited to rolling the coating roll 4 on the painted surface t in the above-mentioned direction, and if it can create the desired texture, the vertical direction along the stone-like unevenness extending vertically and horizontally Alternatively, the coating roll 4 may be rolled in the horizontal direction.

Furthermore, in this example, a color different from the first color is applied as the second color by the paint roller 1 having the coating roll 4 according to the present invention attached on the first color painting surface t2 (FIG. 9A). .
In this example, the second color is a lighter color than the base base.
The second chromatic painted surface t3 formed by applying the second chromatic color has a stone-like texture that makes use of multiple colors (FIG. 10).

For the convenience of showing the drawing in gray scale, the background base and the first and second chromatic colors have been described only in shades, but it is of course possible to implement them with different colors (colors). The present invention is not limited to that shown in FIG. 10, and FIGS. 8 to 10 are merely examples.
Moreover, it is good also as what does not give 2nd coloring in order to shorten delivery date or to give priority to cost by demand.
Moreover, it can implement also as what adds another coloring to the coating surface t by the method similar to a 1st coloring and a 2nd coloring (not shown).

In particular, in the coating on a siding board, it is preferable to apply a silicon-modified resin excellent in weather resistance and low contamination to the second colored coating surface t3 formed above to form a clear finished surface t4. (FIG. 9 (B) and FIG. 10).
However, in the coating other than the siding board, the clear finish surface t4 may not be formed, and it is not excluded that the clear finish surface t4 is not formed in the coating of the siding board.

(Other embodiments)
In the coating roll 4 shown in FIGS. 1 to 3, the plurality of coating material adhering portions 41 are each composed of a piece of felt sheet. In addition, it can implement also as what comprises the coating material adhesion part 4 by overlapping a some sheet piece (FIG. 4 (A) (B) (D) and FIG.4 (C)).
In this example, each of the coating material adhering portions 4 includes a base piece 41a that is directly attached to the covering portion 40a of the roll body 40 with an adhesive, and an intermediate piece 41b that is attached to the base piece 40a with an adhesive. And three felt sheet pieces, a tip piece 41c attached to the intermediate piece 41b with an adhesive. The intermediate piece 41b positioned on the outer side in the radial direction of the roll body 40 with respect to the base piece 41a as the lowermost layer is an upper sheet piece, and the tip piece 41c positioned on the outer side in the radial direction of the roll body 40 with respect to the intermediate layer 41b is intermediate. It becomes an upper layer sheet piece which uses the layer 41b as a lower layer sheet piece.
However, the coating material adhering portion 4 is not limited to the one in which three sheets of felt sheets are stacked, and the coating material adhering portion 4 is formed by stacking two sheets or four or more felt sheet pieces. Can also be implemented.

When the coating material adhering portion 41 is formed by overlapping a plurality of felt sheet pieces as described above, the protruding width of the coating material adhering portion 41 (the total thickness of the respective sheet pieces) is preferably 2 mm to 4 mm. .
However, as long as the effect of the present invention is achieved, the protruding width of the coating material adhesion 41 may be outside the range of 2 mm to 4 mm.
Each of the base piece 41a, the intermediate piece 41b, and the tip piece 41c may have the same shape and dimensions as each other (FIG. 4C), but the intermediate piece 41b is smaller than the base piece 41a, The piece 41c is a smaller piece than the intermediate piece 41b, and the base piece 41a, the intermediate piece 41b, and the tip piece 41c are overlapped and fixed so that the coating material adhering portion 4 tapers in the radially outward direction of the roll body 40. It is preferable to do this. Specifically, in the cross section in the direction intersecting with the axial direction of the roll body 40, each of the sheet pieces is arranged so that the base piece 41a, the intermediate piece 41b, and the tip piece 41c exhibit a plurality of steps (three steps). They are arranged (FIGS. 4A, 4B, and 4D). In particular, it is preferable to dispose the base piece 41a, the intermediate piece 41b, and the tip piece 41c in a pyramid shape having a staircase from the apex (tip piece 41c) of the coating material adhering portion 41 toward each direction of the ridge.

When the base piece 41a, the intermediate piece 41b, and the tip piece 41c have the same shape and dimensions as described above, the coating roll 4 is rolled on the painting surface t, and the painting surface as shown in FIG. A large gap s (gap) is formed between the corner formed by the surface of the roll body 40, which is the coating material non-adhesive layer 42, and the coating material adhesion surface 41, and the depression k when the depression (recess k) on t is applied. There is a concern that the coating material may not adhere to the recess k as scheduled. However, as shown in FIGS. 4A and 4B, the base piece 41a, the intermediate piece 41b, and the tip piece 41c are formed so that the coating material adhering portion 4 tapers in the radially outward direction of the roll body 40. Thus, the gap s can be reduced in the recess k, and the coating can be performed as planned.
