Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a method for attaching a design tape, such as an accent stripe pattern, for decorative purposes to the surface of an article having a cubic curved surface, such as a fuel tank for a two-wheeled vehicle.

(Conventional technology) For example, fuel tanks and side covers for motorcycles.

The surfaces of parts such as fairings are formed by three-dimensional curved surfaces, and after surface treatments such as painting are applied, these surfaces are decorated with design tape such as emblems and accent stripes.

This design tape is usually made of sensitive stone tape, and as shown in Figure 1 (b), the design tape is
On the back side with the adhesive 12, there is a mount (paper pattern) 13 made of rigid paper to keep the shape of the tape until it is used. A protective paper 14 that prevents damage to the tape surface is pasted with an adhesive 15, and when pasting this onto a cubic curved surface 1-, such as a fuel tank of a two-wheeled vehicle, conventionally, the protective paper 14 is pasted onto the surface 1- to which it is pasted. Peel off the backing paper 13 from one end of the tape 1 according to the pre-drawn marking line (wipe off after pasting) 4.
I tried to advance the position of the knot one by one while using a squeegee with a single force to prevent air from being drawn in, but this work required a lot of skill and time, and it was not easy to use the tape. The problem is that the loss due to the failure of pasting No. 1 cannot be ignored.

(Purpose) The present invention has been made in view of the above circumstances, and its purpose is to provide a new method for tying a design tape that is efficient and has a good yield.

(Structure) That is, the adhesive force V of the design tape according to the present invention is:
First, hold the design tape on the inverted model mold by suction and peel off the backing paper for 2t L. Next, apply this tape to the surface of the work to be attached together with the inverted model and temporarily adhere it, then apply sufficient pressure to attach it. The device is characterized in that the protective paper is peeled off at the end.The details will be explained below based on the illustrated embodiment.

The drawings show an example of the method of the present invention for applying hess I-live to a fuel tank of a motorcycle.

The symbol 2 in the figure is a jig used in this method, and the fuel tank W to be striped (Figure 6)
It is formed as an inverted type that matches the external shape of the tape sensor, and a large number of intake holes 4 leading to a suction pump (not shown) are perforated in the tape sensor area on the inner surface ((b) of the same figure).
It is constructed as a tape adsorption section 3, and its upper surface is shaped like a spongy plate and covered with a John material 5.

1. Setting the tape on the jig (Fig. 1) For the jig JA2 constructed in this way, the suction pump shown in Fig. 1 is activated to create a negative pressure in the tape suction section 3. Then, place the tape 1 with the protective paper 14 and the N1 pattern paper 13 stacked thereon so that the release paper 13 is exposed on the surface;
Furthermore, using a hand roller 6 or the like, one end is pressed onto the Kunjong material 5'' to form a cubic curved surface, and the tape l is pressed onto the jig 2.
Securely adsorbs and holds at the required position on the inner surface.

In this step, if the tape 1 with the protective paper 14 and the release paper 13 stacked does not conform to the tape suction part 3 of the jig 2 having a cubic curved surface, the protective paper 14, Il!
As each material of the paper pattern 13, a highly elastic resin film material such as a biaxially stretchable polypropylene film can be used, or the material can be made to fit by heating the jig 2 or the like.

2. Peeling off the release paper 13 (Fig. 2) I! l
& Peel off the pattern paper 13 to expose the adhesive 12 of the design tape 11 on the surface.

3. Temporary adhesion of the tape 1 to the fuel tank W (Fig. 3) The tape 1 with the adhesive 12 exposed on the surface after the GL pattern 13 is peeled off is pressed against the side of the fuel tank W together with the jig 2. . At the same time, the operation of the suction pump (not shown) is stopped, and the tape 1 is completely transferred from the jig 2 while being temporarily adhered to the fuel tank W.

4. Adhering the tape 1 to the fuel tank W (Fig. 4) After the jig 2 has been removed, the tape 1 that has adhered to the surface of the fuel tank W is covered with a layer of protective paper 14 or a soft resin, etc. A pressure tracing process is performed using a squeegee 7 made of a squeegee 7 to firmly adhere the tape to the surface of the tank W, and finally, the protective paper 14 is peeled off from the top of the tape L (FIG. 5), completing the entire process.

(Effects) As described above, according to the present invention, the decorative tape with the mount still attached is shaped into a cubic curved surface and placed in an inverted mold so that it can be brought into contact with the surface of the workpiece together with the mold. By handling the tape in its shape retained by the mount, there is no room for individual differences in the work, and
By dividing the work into several parts such as tape centration, temporary pasting, and final pasting, it is possible to appropriately manage the process, and furthermore, each process can be fully automated.
