Description

Veneer and its manufacturing method {VENEERS AND THE METHOD FOR FABRICATING THE SAME}

The present invention relates to veneer used in the field of architecture, interior, furniture, and more particularly to a veneer and a method of manufacturing the same long storage period and easy construction.

Recently, as industrialization progresses rapidly, it becomes difficult to find places that retain their natural appearance not only in cities but also in rural areas such as rural areas and fishing villages. As a result, people have a kind of nostalgia in their natural appearance, and this is reflected in industrial design and architecture, so they prefer traditional wooden houses and furniture, and related industries are growing into high value-added industries. .

Even if it is not such a solid wood, the patterned wood that is cut and joined to a thin thickness to reproduce the atmosphere of the wood is also widely used in the field of architecture, interior, furniture.

Although there are many forms and methods of manufacturing such veneers, the contents disclosed in Korean Patent Publication No. 97-548, "Method and Apparatus for Manufacturing Veneers and Their Veneers," which were published early on January 21, 1997, are given as examples. Explain.

As disclosed in the patent publication, a natural veneer with a thin slice of natural wood is prepared, and a fiber sheet on which the resin penetrates evenly on both sides by resin impregnating a nonwoven fabric made of cotton, viscose rayon, nylon, etc. is formed on the back of the natural veneer. A manufacturing method characterized by pressing by roller pressing or thermocompression, and a veneer having a configuration in which a thin nonwoven fabric impregnated with resin on the back side of natural veneer is pressed.

In addition, the veneer feeder for supplying the natural veneer thin sliced to a predetermined thickness, the spring buffer roller for guiding in a correct posture without twisting by adjusting the veneer released from the feeder in the width direction, and the natural veneer released Cylinder actuating roller which presses down to correct distortion, nonwoven feeder for supplying nonwoven fabric with resin surface impregnated on the front and back, guider for overlapping natural veneer and nonwoven fabric, and natural feeder supplied through this guider There is also disclosed a veneer manufacturing apparatus comprising a thermocompression unit consisting of at least three press rollers for thermocompression bonding veneer and nonwoven fabric, and a rewinder for winding a natural veneer on which the nonwoven fabric is compressed on the back side.

Since these veneers are made of solid wood, they have area limitations.For example, veneers 30cm wide and 240cm long have to be glued to the site by workers when they need to construct a larger area. Apply by coating with a transparent film on the adhered veneer surface.

However, the prior art as described above has the following disadvantages.

First, when the construction is larger than the individual veneers, the technicians will be hand-worked in the field, so it is inevitable to spend excessively in terms of time and expense. Since solid wood has different shades according to parts, the patterned wood cuts have different shades, but when it is attached by hand at the construction site instead of a manufacturing plant, it is difficult to find veneers with similar contrasts. There is a problem.

Secondly, wood has the property of splitting along the grain, and because it is used to cut the wood thinly, it is very difficult to process. Accordingly, as a result of checking the defective rate at the construction site, it becomes about 40% and there is a problem of raising the cost.

Third, after the veneer is manufactured, it is easily altered due to external factors (for example, temperature, humidity, etc.), that is, its shelf life is short, and not only is difficult to store for a long time, but also the surface floats due to air bubbles after construction. . In fact, although there is a difference in degree, it was found that after about 6 months bleaching occurs.

Fourth, even though it is a simple operation, the loss of the veneer due to poor construction, the wrinkles of the veneer itself are severe, and the time required is long, and there is a lot of manpower to mobilize, as well as adhesion and coloring, In the surface treatment, etc., a separate technique is required.

Fifth, unless a separate adhesive and surface treatment means is mobilized, the material that can be bonded is limited, and in order to construct a large area, a plurality of veneer members must be joined.

The present invention pays attention to the fact that separate work, time, and manpower are required at the construction site because the veneers to be supplied in the form of finished products are distributed in the form of semi-finished products. It is based on the fact that parts can be eliminated.

The present invention has been made to overcome the above-mentioned problems, excellent storage properties, can be used by people without construction technology, as well as veneer wood and a method for manufacturing the same to reduce the time, manpower, cost required for construction The purpose is to provide.

Another object of the present invention to provide a veneer and a method of manufacturing the same that can be constructed in a large area.
