Description

Description: TECHNICAL FIELD The present invention relates to a method for producing a coating roller which is used for coating the entire surface of a roller with coating and rotating the roller.

[Conventional technology]

The conventional coating roller has a shape as shown in FIGS. 4 and 5. The manufacturing method of the coating roller a shown in FIG. 4 is performed as follows.

First, a resin-impregnated base paper is spirally wound in three or six layers to make a paper tube b endlessly. The endlessly made paper tube b is dried with a tunnel dryer to form a strong paper tube b. Then, a brush cloth c made of pure bristles or synthetic fibers is wound around and adhered to the paper tube b, and the paper tube b around which the brush cloth c is wound is cut according to the length dimension 1 of the roller body d. A roller handle e is fitted and fixed in the paper tube b of the roller body d to obtain a product.

The manufacturing method of the coating roller a'of FIG. 5 is performed as follows. First, a synthetic resin pipe b'having a predetermined length is cut according to the length dimension 1 of the roller body d '. Then, a brush cloth c longer than the dimension length l of the synthetic resin tube b'is wound and bonded by aligning one end of the brush cloth c with one end of the synthetic resin tube b '. Then, the other end of the brush cloth c protruding from the other end of the synthetic resin tube b'is folded into the other end opening of the above-mentioned synthetic resin tube b ', and the plug f is prevented so that the folded brush cloth c does not return to its original state. Then, the roller handle e is fitted from the one end opening of the synthetic resin pipe b'and fixed to obtain a product.

[Problems to be Solved by the Invention]

However, in the method of manufacturing the coating roller a shown in FIG. 4, it is possible to manufacture a plurality of roller bodies d in one step, and the raw material cost is relatively low, but the finished product Since there is no brush cloth c on the end surface of the roller body d in the axial direction, almost no paint can be contained in this portion, so even if the roller body d is rolled along the corner of the wall surface, I can't paint. In addition, the roller handle e must be used from the end face of the synthetic resin pipe b in accordance with the length dimension 1 of the synthetic resin pipe b so that the paint does not enter the inside.

The manufacturing method of the coating roller a'shown in FIG. 5 can be said to be an improvement of the problems of the manufacturing method of the coating roller a shown in FIG. That is, since the coating roller a ′ in FIG. 5 has the brush cloth c on one end surface of the roller body d ′ in the axial direction, the coating material can be sufficiently contained in this portion, and the roller can be formed along the corner of the wall surface. If the body d is rolled, the corners of the wall surface can be easily painted.
Further, the roller handle e'also has a length dimension l of the synthetic resin pipe b '.
Shorter ones are better. However, the synthetic resin pipe b '
Is to be cut in advance to the length dimension 1 of the roller body d ', and a brush cloth c longer than this is wound around and adhered to the synthetic resin tube b', and the brush cloth c is folded into the synthetic resin tube b '. Since a large number of roller bodies d'cannot be manufactured at one time, the number of steps is increased, and the raw materials and parts are expensive, the coating roller a'of FIG. 5 is expensive as a whole.

Therefore, even though there is a brush cloth on one end surface of the pipe, the manufacturing process can be simple and easy, inexpensive raw materials can be used, and the cost can be reduced as a whole. It is an object to provide a method for manufacturing a roller.

[Means for solving the problem]

In order to solve the above problems, the method for producing a coating roller of the present invention is a tube forming step of forming a tube of a predetermined length corresponding to at least a plurality of roller bodies, and the tube formed in the tube forming step. A brush cloth winding step of winding a brush cloth made of pure bristles, synthetic fibers or the like; a tube cutting step of cutting the tube wound with the brush cloth into a predetermined length corresponding to the roller body; A step of axially removing a predetermined length of the one end of the tube having the length, leaving the brush cloth, and folding the remaining brush cloth into an opening of one end of the tube to fix the tube to the tube.

Also, a tube forming step of forming the tube endlessly, a brush cloth winding step of endlessly winding a brush cloth made of pure bristles, synthetic fibers or the like around the endlessly formed tube, and winding the brush cloth A tube cutting step of cutting the attached tube to a predetermined length, and removing one end of the tube having a predetermined length in the axial direction by leaving a brush cloth, and leaving the remaining brush cloth at one end of the tube. It may be provided with a step of folding into the opening and fixing to the tube.

 Furthermore, it is even better if the tube is a paper tube.

[Action]

According to the above configuration, the brush cloth is wound around the tube formed to have a predetermined length corresponding to at least the plurality of roller bodies, and the brush cloth is cut into the predetermined length to form a plurality of roller bodies. Remove one end of the brush cloth in the axial direction for a predetermined length, and fold the remaining brush cloth into the opening on one end of the tube, so that multiple roller bodies can be made at the same time and there is a brush cloth on one end surface of the tube. You can make a roller.

In addition, if the brush cloth is endlessly wound around the endless tube and is cut continuously to a length corresponding to the roller body, the roller body can be made continuously and in a large amount.

Further, if the tube is a paper tube, it can be easily made compared with other materials.

〔Example〕

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.

1 and 2 are process diagrams showing the steps of the method for producing a coating roller of the present invention, and FIG. 3 is a sectional view of a coating roller produced by the method of the present invention.

In both figures, first, the rotating shaft (not shown)
A plurality of base papers 1 impregnated with a resin are sequentially wound on the upper surface in a spiral shape to continuously form a paper tube 2. At this time, the base paper 1 is impregnated with a resin in order to impart a predetermined strength and water resistance to the paper tube 2, and the paper tube 2 is usually the base paper 1.
3 to 6 sheets are stacked, and in this embodiment, 4 sheets are stacked. The paper tube 2 thus formed passes through a tunnel type dryer 3, and the resin impregnated in the base paper 1 is dried in the process to become a strong paper tube 2 and water resistance and the like are imparted. It
Then, a brush cloth 4 made of pure bristles, synthetic resin or the like is wound around the paper tube 2 in a spiral shape and adhered. The paper tube 2 to which the brush cloth 4 is adhered is sequentially cut by a cutter 5 to a required length. This cut product is the roll body 6
The resulting roll main body 6 is formed from one end of the roll main body 6 with a drill 7 in a direction of an arrow A, leaving a brush cloth 4 and a small paper tube 2, as shown in FIG. The tube 2 is scraped. Then, the paper tube 2 is scraped to a predetermined position shown in FIG. 2B, and the remaining brush cloth 4 and the slightly remaining paper tube 2 are removed from the inner circumference of the paper tube 2 as shown in FIG. It is commercialized by simply folding it into the surface 2a. By doing so, the brush cloth 4 also exists on the axial end surface of the paper tube 2, and the corner portions of the wall surface can be coated at the same time. Further, as shown in FIG. 2D, not only the brush cloth 4 remaining in the inner peripheral surface 2a of the paper tube 2 and the slightly remaining paper tube 2 are simply folded but a plug 8 is fitted between them. You may fix together.

After that, as shown in FIG. 3, the roller handle 9 is inserted from the opening end surface of the roll body 6 to insert the inner peripheral surface of the paper tube 2.
If the spring 14 is firmly fixed to the 2a, the coating roller 10 is completed.

The roller handle 9 is a shaft 11 having a ladle shape.
And a shaft portion inserted into the paper tube 2 at the tip of the shaft body 11.
A tip bearing 12 and a base bearing 13 respectively provided on 11a, and a spring 14 provided between the tip and base bearings 12 and 13 for firmly fixing the inner peripheral surface 2a of the paper tube 2 and the roller handle 9 to each other.
And a grip 15 fixed to the base end of the shaft body 11.

In the coating roller 10 manufactured by the method of the present invention, which has the above-mentioned steps, the dimension 1 of the roller body 6 is smaller than that of the coating roller a shown in FIG. I can.

〔The invention's effect〕

As described in detail above, according to the method for manufacturing a coating roller of the present invention, a brush cloth is wrapped around a tube formed to have a predetermined length corresponding to at least a plurality of roller bodies, and this is cut into a predetermined length. To make a plurality of roller bodies, remove one end of the tube of this roller body axially for a predetermined length leaving the brush cloth, and fold the remaining brush cloth into the one end opening of the tube,
At the same time, it is possible to make a plurality of roller bodies at the same time and to easily make a painting roller having a brush cloth on one end surface of the pipe. Therefore, it is possible to inexpensively manufacture the painting roller having the brush cloth on one end surface of the pipe.

In addition, if the brush cloth is endlessly wound around the endless tube and is cut continuously to a length corresponding to the roller body, the roller body can be made continuously and in a large amount. Therefore, it becomes possible to make the coating roller having the brush cloth on one end surface of the pipe at a lower cost.

Further, if the tube is a paper tube, the cost is lower than that of other materials, so that the coating roller can be manufactured at a low cost.
