Description

[Detailed description of the invention] The present invention relates to a method for cutting off hair transplanted products.

Among flocked products, when flocking piles only in areas where mating parts come into sliding contact, such as automobile weather strips and door glass runs, conventional methods as shown in FIGS. 1 and 2 have been adopted. 1st,
Figure 2 shows the case of a weather strip, but the first
In the case of the one shown in the figure, a protrusion 2 is integrally molded at the parting point of the flocking on the surface of the weather strip 1, and an adhesive 3 is applied to the surface to be processed using a roller (not shown), and then the well-known electrostatic flocking method is used. In the method shown in FIG. 2, the surface to be processed is partitioned by providing a step 5 at the end of the flocking, and the adhesive 3 is applied to this surface by rollers in the same manner as described above. The pile 4 is flocked using the electrostatic flocking method.

However, with these methods, the above-mentioned protrusions 2 and steps 5 cannot be formed with a large difference in height in relation to the mating part, and are constrained to be low. There was a problem in that the flocking protruded onto other surfaces, and in the end, the flocking was applied to surfaces that did not require flocking, making the flocking parting line unclear and detracting from the product value.

Therefore, there is a method of flocking by masking the surface that does not require flocking and applying adhesive by spraying etc. only to the surface to be processed, but with this method, although the masking makes the flocking separation line clear, However, the masking process requires a very large number of man-hours, which not only significantly reduces productivity, but also increases costs due to the use of masking materials.

In view of the conventional situation, the present invention has been developed to reduce the number of man-hours and
To provide a method for cutting off hair transplantation that can make the cutting line for hair transplantation clear without increasing costs.

In order to achieve the above object, in the present invention, a cut-off lip is integrally molded at the parting point of the product to be flocked with a thin-walled easily tearable part, and after the flocking process, this cut-off lip is attached to the easily tearable part. By removing more tears, the parting line for the flocking is made clearer.

Hereinafter, an embodiment of the present invention will be described in detail using an automobile weather strip as an example of a product to which hair flocking is applied, and the same parts as those of the conventional structure are denoted by the same reference numerals.

That is, in the method of the present invention, as illustrated in FIG. 3, a tear-off lip 10 is previously integrally formed at the parting point of the weather strip 1 through a thin easily tearable part 11. This easily tearable part 11,
The cut-off lip 10 can be easily formed by integral extrusion molding of the weather strip 1.
Further, since the cutting lip 10 is to be torn and removed, there is no restriction on the protruding height.

Then, the adhesive 3 is applied, for example, by spraying, to the surface of the weather strip 1 having the cut-off lip 10 to be processed. At this time, the adhesive 3 is prevented from scattering toward the surface where flocking is not required by the cutting lip 10. After applying this adhesive 3, the pile 4 is flocked by a well-known electrostatic flocking method. pile 4
Naturally, hairs are also flocked on one side of the tear-off lip 10, that is, on the side surface of the weather strip 1 facing the surface to be processed, where the adhesive 3 is applied. Since the hair is torn and removed from the easily tearable part 11 after the flocking process, there is no problem, and by tearing and removing the tearing lip 10, the flocking parting line on the surface of the weather strip 1 can be made clear.

As described above, according to the method of the present invention, the cut-off lip can reliably prevent the adhesive from spilling out onto other surfaces, and furthermore, since the cut-off lip is torn and removed after the pile is flocked, the product surface The flocking parting line can be clearly defined using the torn part of the cutting lip as a boundary, and the commercial value can be further increased. In addition, the tear-off lip is not an original functional component of the product, but is a so-called waste material, and there is no requirement for strength, so it can be made as thin as possible to minimize material loss, which reduces cost. The extra cost is only a small amount, which is advantageous in terms of cost, and there is no increase in the number of man-hours for flocking, so it has a great practical effect in that it can be provided at a low cost.
