JPS5918042B2 - Method for manufacturing materials such as patterned sandals - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to footwear such as sandals, bags such as bags,
The present invention also relates to a method for producing a patterned material that can be applied to a variety of items such as various display items.

Taking the material of sandals as an example, the treads of these sandals are decorated with various patterns.

Since the method of forming these patterns was generally by printing, many of the patterns peeled off after being layered for a long time, which did not necessarily satisfy the tastes of users.

Particularly when the pattern is an important design point, such defects are fatal, and therefore, when looking at conventional sandals, most patterns are provided on sandal bands, etc., which do not have such burdens. It was nothing more than

The present invention was made in view of the drawbacks of the conventional type, and as a material of this kind, EVA resin is easily compressible and deformed in cold or hot (although it is more pronounced in hot). The present invention aims to provide a method for forming patterns etc. by skillfully utilizing the properties of such materials.

That is, in the method of manufacturing materials such as sandals with patterns of the present invention, a foamable decorative material is applied to a foamable base material, and then a part of the decorative material is pressed with a mold having a predetermined uneven pattern. The cosmetic material is crushed and immersed in the base material, and then the decorative material in the remaining portion other than the crushed and penetrated portion is scraped off, and the portion to which the decorative material is applied is heated and expanded without eating afterwards. It is something.

The present invention will be specifically described below based on illustrated embodiments.

First, prior to explaining the manufacturing method of the present invention, the form of the material 1 for sandals etc. manufactured by the present invention and the sandals made into finished products using the same will be described with reference to FIG.

As an example, this material has the form of a sandal material, but as mentioned earlier, it is not limited to sandal material, but can be applied to various types of footwear, bags, display items, etc. It is possible.

This material has a shape in which the decorative material 3 is submerged in the base material 2, and the portion where the decorative material 3 is exposed in relief on the surface forms a decorative pattern.

Incidentally, as shown in FIG. 1A, when this material is used for sandals, a band 4 or the like is provided as appropriate.

The manufacturing method of the present invention will be explained below.

First, as shown in FIG. 2A, the decorative material 3 is stretched over a fairly wide area on the base material 2.

Incidentally, when the base material 2 and the decorative material 3 are used as sandal materials, EVA resin is often used, but any so-called foamable resin that can be compressed and deformed may be used.

When applying the decorative material 3 to the base material 2, an adhesive such as so-called rubber glue is used.

The material 1 thus prepared is compressed from above using a pressing die 5 having a concavo-convex pattern to be provided.

In this case, as shown in the opening of FIG. 2, the decorative material 3 is crushed by the protruding portion 5' of the mold 5, so that only that portion of the decorative material 3 sinks into the base material 2.

Of course, in the case of EVA resin, more favorable results can be obtained if this process is carried out while the material is heated, but it is not necessarily necessary to process it under heated conditions.

Sufficient effects can be obtained even at so-called room temperature (cold working).

After processing in this way, as shown in FIG. 2C, the remaining portion of the cosmetic material 3 other than the crushed and infiltrated portion is skived off with a skiving blade 6 or scraped off with a puff.

Incidentally, when such a process is performed under heating, work on this area or grinding work with the puff is done after cooling.
In this case, in a later step, the patterned portion is heated, so that the internal air bubbles expand and the patterned portion is raised to some extent, resulting in a so-called relief-like convex pattern.

As described above, in the present invention, the material to be patterned is sufficiently embedded in the base material, so that it exhibits sufficient durability without peeling off even under severe use.

Incidentally, in the embodiment shown in FIG. 2, the decorative material 3 is stretched across the entire surface of the base material 2 over an area that is considerably wider than the pattern. When the entire upper surface of the decorative material 3 is made to be covered, no unnecessary unevenness is generated after processing, and a very favorable result can be obtained.

However, if such elaborate finishing is not necessarily required, it is of course possible to process the decorative material so that it is partially provided in a slightly wider area than the area on which the pattern is engraved.

In particular, according to the present invention, the decorative material is crushed and integrated with the base material, and then heated to promote expansion, so that it is possible to create a relief-like foam pattern, which makes it possible to create interesting designs. It is.
