## Title
Process for producing a surface finish sheet

## Abstract

A process for producing a surface finish from natural materials, whereby the obtained surface finish may be in the form of any shape, and preferably is in the form of a thin sheet having a nature that has a relationship with the form of a product desired to be finished.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a process for producing a surface finish sheet from natural materials such as materials from plants by using the interlock friction of the natural materials in producing the surface finish sheet, without using any binder.
2. Description of the Related Art
There are many methods available for the production of a surface finish for covering the surfaces of any articles or implements such as a surface finish of a plastic or synthetic fiber nature or such as in the form of composite materials. However, either during the stage of production or during the stage of application, a binding chemical is required, and such may cause pollution.
Many natural materials have been used for this purpose. However, mostly, a framework of an implement must be produced first and, subsequently, the required natural material is used for binding the framework such as by winding or adhesion by any means, and the framework is usually made from rattan. At present, the use of rattan is discouraged.
SUMMARY OF THE INVENTION
This invention is directed to a process for producing a surface finish sheet from natural materials by using friction between the materials without using any sort of binder.



FIG. 1 illustrates a device for whittling.



DETAILED DESCRIPTION OF THE INVENTION
This invention is directed to a process for producing a surface finish from natural materials. The surface finish may be of any shape, and preferably is in the form of a thin sheet having a feature relating to the feature of a product that is desired to be finished.
The process of this invention comprises the stage of producing surface finish strips that should be made from natural materials such as materials from plants, for example, Lygodium flexuosum vine, bamboo, vetiver grass, etc., although other materials can be used such as metals. The process of this invention also comprises the stage of producing a surface finish sheet from the surface finish strips by using friction between the surface finish strips.
The stage of producing these surface finish strips essentially comprises the shaping of a natural material into a thin strip with a consistent size throughout its length. This may be carried out by various methods such as whittling or rolling. One method proposed as an embodiment in this invention is whittling. The natural material which has been selected as being suitable for use, namely, having a size and color as required and which may have been dyed with a desired color, is first subjected to whittling. The device 10 for whittling comprises a metal sheet device 12 which has several sized holes 14 which can downsize the natural material gradually. The material is first inserted to pass properly through a hole, sized to whittle the material, and then pass through a smaller hole, sized to further whittle the material, until a width and a thickness of the strip as required is obtained. A suitable width should be 0.5-5 mm and, more preferably, is 1-2 mm, whereas a suitable thickness should not be greater than 1 mm, although this thickness is not critical. The strips should be whittled to a suitable size as required and be even. It is optional to dye these strips after their desired size is obtained.
The stage of producing a surface finish sheet according to this invention is the fabricating and fixing of these strips to make a sheet with multicolored designs as required. The method of this invention can be accomplished by using friction between the surface finish warp strips and weft strips to enable them to adhere together. The proposed method of the invention may be carried out by fixing the warp strips longitudinally to a plate of suitable size, which should be larger than an area to be covered with the produced surface finish sheet, without having predetermined specific values and just depending upon a desire and the method of fabricating and fixing of the produced surface finish sheet to the surface of a desired material or equipment. The fabricating and fixing of each surface finish strip may be chosen to be adjacent to one another or interspaced as appropriate. In this regard, it may be optional to alternate the colors to create any designs as required.
As an embodiment of the invention, it is optional to insert surface finish weft strips under or over the surface finish warp strips and therefore the surface finish weft strip which has been inserted under or over will be parallel to the width of the plate. It may be optional to insert the surface finish weft strips under and over the surface finish warp strips in an alternate order, in a proportion of 1/1, or in another proportion.
As another embodiment of the invention, it may be optional to insert surface finish weft strips in a diagonal direction to surface finish warp strips by selecting a method of inserting surface finish weft strips to be under or over the surface finish warp strips.
In addition, it may be optional to insert surface finish strips vertically, longitudinally, laterally, or diagonally by alternating them and it may be optional to insert them in any sequence or in any proportion.
In this regard, surface finish strips of different sizes may be selected for fabrication in an alternate manner as required.
In addition, it is optional to use other materials, either natural materials such as materials from plants, materials from animals, or synthetic materials to alternate the designs as required by alternate insertion in any sequence as mentioned above, whereby the preferred material may be, for example, the wings of metallic wood-boring beetles.
The feature of the invention of producing a surface finish sheet without using a binder is obtained because the surface finish strips will bind and adhere to one another by the friction of each surface finish strip. With this feature, it is possible to remove the obtained surface finish sheet from a plate and attach the surface finish sheet to the surface of any article or implement required to be finished, whereby said fixing may be achieved without using any binder.
It is possible to use a surface finish sheet product obtained from the production process in finishing the surface of any articles or implements.
