The method of forming a soft soft layer through an injection method of a solution type according to the present invention, as shown in FIG. 1, ultimately forms a solution resin 20 constituting the soft soft layer on a base sheet 10 And, the lower surface of the solution resin 20 provides a technical idea for various patterns to appear.

As revealed in the background art, the existing techniques have had the problem that the resin in the solution state is confined within the border forming the seal boundary, and it takes a few tens of hours for the solution-state resin to dry and harden. Disclosed is a technical idea that can form a resin in a solution state even if a thread edge does not exist.

As shown in FIG. 1, a base sheet 10 for forming patterns and soft soft layers of various designs is prepared and not a boundary line existing on the base sheet 10, but a preset virtual boundary line ( L).

The imaginary boundary line means various imaginary lines programmed on the base sheet 10, as shown in FIG.

Since an edge that actually exists on one base sheet 10 or a barrier rib is not formed on an edge that actually exists, it may not be possible to visually observe. Of course, when the solution resin 20 is injected and cured, the boundary line may be visible to the naked eye.

After preparing the base sheet 10, a predetermined virtual boundary line is formed, and thereafter, the base sheet 10 is a predetermined working position (P) that is a desired position using a roller (see FIGS. 7 to 9). ), various subsequent procedures are performed at this predetermined working position (P).

Thereafter, as shown in FIGS. 1 and 7, along the inner surface of the preset virtual boundary line L set on the base sheet 10, the heat-melted soft resin is sprayed in the form of particulates by spraying the heat-melted soft resin The resin line 21 is formed.

For example, when the preset virtual boundary line is set as an eagle-like shape on the base sheet 10, for example, to form a heat-melted soft resin line 21 along the imaginary virtual boundary line. do.

As shown in FIG. 6, a plurality of preset virtual boundary lines L that are variously formed on one base sheet 10 may be set, and a soft resin line ( When 21) is formed, it is moved to the side and is formed by spraying the soft resin line 21 in the form of particles in turn. In other words, if the soft resin line is formed along the imaginary border line L of the rabbit shape, then the soft resin line L of the chicken shape may be formed, and then, in the form of a turtle shape, a lizard shape, and the like. . During the final formation of the soft resin line L, the first soft resin line L and the subsequently formed soft resin lines L are cured in turn.

As shown in FIG. 2, before forming the soft resin line L along the virtual boundary line L, the step of forming the visible light reflecting layer 30 may be further included.

Although shown in FIG. 2 after step s10, the visible light reflection layer 30 may be formed even after step s20.

In the case of the visible light reflecting layer 30, as shown in FIG. 9, the visible light reflecting layer 30 is formed by selectively spraying fine particles that selectively reflect the wavelength of visible light in a preset virtual boundary line.

3 and 8, after forming and curing the soft resin line 21 along the imaginary boundary line L, the soft resin line 21 itself forms one border wall. Bar, the molten solution resin 20 may be selectively coated in the soft resin line 21.

More specifically, the solution resin 20 is injected by matching the height of the soft resin line 21, and the solution resin 20 is cured.

6, the soft resin line 21 is sequentially formed along various virtual boundary lines L, and then the solution resin 20 is formed while the solution resin 20 is formed in the initially formed soft resin line 21. The shape of injecting is moved one after the other.

Here, the solution resin 20 may be sufficiently injected to have a uniform height in the soft resin line 21, as shown in FIG. 8, but is optionally randomly injected according to the shape of the visible light reflecting layer 30 The soft solution resin 20 may also be selectively injected to form an uneven surface without being flat.

In the case of the soft resin line 21, if the thickness is thickened from the beginning, it does not dry easily, and accordingly, hardening does not occur in a short time, so it may be difficult to form the thickness thickly as desired.

In this case, as illustrated in FIGS. 4 and 10, an additional soft resin line 21-1 heat-melted on the soft resin line L may be additionally formed to increase its thickness. Of course, this process can be repeated to match the desired height of the soft resin line 21.

Thereafter, the solution resin 20 may be additionally injected into the interior of the final soft resin lines 21 and 21-1 whose thickness is increased to increase the thickness of the solution resin 20.

Since the base sheet 10 flowing on various rollers 1 and 2 and the soft soft layer in which the soft soft solution resin 20 is cured may be separated from each other in the bending process of the base sheet 10, FIGS. As shown in FIG. 10, the heat-melted soft resin outline 22 may be formed along only the outer surface of the preset virtual boundary line L set on the base sheet 10.

In the case of the soft resin outline 22, it is difficult to make it visible to the naked eye, and since it has to be distinguished from the external shape of the virtual boundary line L to be targeted, its thickness is 20% or less of the soft resin line L. It is important.

In the case of the soft resin outline 22, as shown in FIG. 10, the thickness gradually decreases as it moves away from the preset virtual salute line L, and as described above, the base sheet 10 It is important to perform the role of a medium so that it is bent at the same time as it is bent, and is bent by itself to maintain adhesion between the base sheet 10 and the soft resin line 21.

The solution resin 20 formed by spraying in the form of heat-melted particulates forms a soft soft layer, as shown in FIG. 11, the upper surfaces of the solution resins may be selectively rugged. When the soft soft layer is pressed and moved between rollers, the upper surface is flattened by being pressed, and then, the thin film layer 40 is formed. When passing between the rollers, the soft soft soft upper layer is formed with a thin film layer.

In the case of the final produced product, it is of a soft soft layer having a step height of various heights, and a uniform thin film layer 40 is applied to the upper surface of the soft layer, and in the process of rolling with other rollers in the process of being delivered to the consumer, Even if the tensile force in the longitudinal direction and the compressive force due to the up and down pressure are applied, when the tensile force and the compressive force are released, it can be provided as a reliable product through the original restoration force.

The scope of rights of the present invention is determined by the matters described in the claims, and the parentheses used in the claims are not described for selective limitation, but are used for clear components, and the descriptions in parentheses are also interpreted as essential components. Should be.
