Abstract

The present invention relates to a method for manufacturing decorative plywood where the same pattern is formed in circumferential, upper, and lower surfaces. According to the decorative plywood manufacturing method of the present invention, the decorative plywood is formed by a decorative sheet (20) being attached to upper and lower surfaces of a plywood main body (10). The plywood main body (10) is formed by multiple wood sheets adhering to each other for stacking. The decorative sheet (20) has multiple laterally extending stripes. The decorative sheet (20) is formed by the cutting of a side surface of a wood block (30) that is formed by multiple wood sheets adhering to each other for stacking. According to the present invention, similar stripes are formed in the circumferential, upper, and lower surfaces, and thus a sense of uniformity can be achieved. In addition, disharmony between the patterns in the upper and lower surfaces and the circumferential surface can be prevented.

Description

Method of manufacturing plywood

The present invention relates to a method for manufacturing a decorative plywood having a circumferential surface, an upper surface and a lower surface having the same pattern.

Generally, as shown in Fig. 1, a plywood which is widely used as a finishing material for a room or a raw material for manufacturing furniture is produced by adhering a plurality of thinly cut wood sheets to each other using an adhesive so as to be stacked one upon the other, Is characterized by high strength and strong resistance to moisture and torsion.

However, since the plywood 1 is produced by laminating a plurality of wood sheets, the top and bottom of the plywood 1 have a natural pattern such as a natural neck, while stripes extending in the lateral direction appear on the peripheral face. There is a problem that the user may feel an uncomfortable feeling when the interior is closed or the furniture is made.

Therefore, recently, as shown in Fig. 2, a decorative sheet 2 having a wooden pattern is attached to the peripheral surface of a plywood 1 produced by laminating wood sheets, and as shown in Fig. 3, A method has been developed in which the upper and lower surfaces of the plywood 1 have a natural pattern such as natural wood.

The decorative sheet (2) is made by thinly cutting a log.

By the way, after the plywood 1 is manufactured, it is cut and used in various sizes and forms according to the purpose.

However, as described above, as shown in Fig. 4, when cutting the plywood 1 having the decorative sheet 2 with a wooden pattern on its peripheral surface, stripes extending in the lateral direction appear on the cut surface , This method has a problem that it is difficult to prevent discomfort due to different patterns of the upper and lower surfaces of the plywood 1 and the peripheral surface.

Therefore, there is a need for a new method to solve such a problem.

Patent No. 10-0164926, Registration Utility Model No. 20-0340066,

It is an object of the present invention to provide a method of manufacturing a decorative plywood having a circumferential surface, an upper surface and a lower surface having the same pattern.

According to an aspect of the present invention, there is provided a method of manufacturing a wood block, comprising the steps of: preparing a plywood board body by adhering wood sheets to each other to form a laminated board body; A step of cutting the side surface of the wooden block 30 to produce a decorative sheet 20 and a step of adhering and fixing the produced decorative sheet 20 to the upper and lower surfaces of the wood sheet / RTI >

According to the method for manufacturing a decorative plywood according to the present invention, the decorative plywood comprises a decorative sheet 20 having a plurality of stripes formed laterally on the upper and lower surfaces of a plywood main body 10 formed by adhering a plurality of wood sheets to each other, Wherein the decorative sheet 20 is formed by cutting a side surface of the wooden block 30 formed by adhering a plurality of wooden sheets so as to be stacked one upon the other.

Accordingly, since the stripes are formed on the upper and lower surfaces and the circumferential surface in a similar manner, unevenness is imparted to the upper and lower surfaces and the circumferential surface of the upper and lower surfaces.

1 is a perspective view showing a general plywood,
FIGS. 2 to 4 are reference views showing an example of a plywood sheet having a sheet on its peripheral surface,
5 is a reference view showing a decorative plywood according to the present invention,
6 to 8 are reference views showing a method of manufacturing a decorative plywood according to the present invention,
9 is a perspective view showing a state in which the decorative plywood according to the present invention is cut.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

5 to 9 illustrate a decorative plywood according to the present invention. The decorative plywood according to the present invention comprises a plywood main body 10 formed by adhering wood sheets so as to be stacked one on the other, And a decorative sheet 20 to be attached and fixed to the base sheet.

To explain this in more detail, the plywood main body 10 is manufactured by attaching a plurality of wooden sheets having a thickness of about 1.5 mm to each other using a phenol resin adhesive, and then heating and pressing them with a press.

The structure of the plywood main body 10 is the same as that of general plywood.

At this time, the plywood body 10 is manufactured to have a size of 90 mm (thickness) * 1220 mm (width) * 2240 mm (length).

The decorative sheet 20 is constituted by cutting a side surface of a wooden block 30 constructed by adhering a plurality of wood sheets so as to be stacked one upon the other.

As shown in Fig. 6, in the same manner as the above-described plywood body 10, the wood block 30 has a wood sheet having a thickness of about 1.5 mm and attached to each other using a phenol resin adhesive, It is produced by heating and pressing with a press.

At this time, the wood block 30 is manufactured to have a size of about 600 mm (thickness) * 600 mm (width) * 2500 mm.

As shown in FIG. 7, the decorative sheet 20 is manufactured by thinly cutting the side of the wooden block 30 to a thickness of about 1.5 mm after the wooden block 30 is completely dried.

The decorative sheet 20 has a width of about 600 mm and a length of about 2500 mm which is slightly longer than the length of the upper surface of the plywood main body 10, about half the width of the upper surface of the plywood body 10. As shown in Fig. 8, after two decorative sheets 20 are attached to the upper and lower surfaces of the plywood body 10, the periphery of the decorative sheet 20 protruding from the upper surface of the plywood body 10 The decorative sheet 20 can be attached to the upper and lower surfaces of the plywood main body 10 by polishing the surface.

According to the decorative plywood and decorative plywood manufacturing method configured as described above, the decorative plywood comprises a decorative sheet (not shown) having a plurality of laterally extending strips formed on the upper and lower surfaces of a plywood body 10 formed by adhering a plurality of wood sheets The decorative sheet 20 is formed by cutting a side surface of a wooden block 30 formed by adhering a plurality of wood sheets so as to be stacked one upon the other.

Accordingly, since the stripes are formed on the upper and lower surfaces and the circumferential surface in a similar manner, unevenness is imparted to the upper and lower surfaces and the circumferential surface of the upper and lower surfaces.

Particularly, as shown in Fig. 9, the decorative plywood thus constructed has the same stripe pattern as the upper and lower sides on the cut surface even if cut to an appropriate size. In any case, it is possible to prevent the patterns of the upper and lower surfaces from being different from each other There are advantages.

In the case of this embodiment, the decorative sheet 20 has been illustrated as cutting the side surface of the wooden block 30 thinly. However, in a state where the side surface of the wooden block 30 is rotated by 90 degrees so as to be positioned on the upper side, It can be manufactured by thinly and horizontally cutting.

In addition, the sizes of the plywood body 10 and the wood block 30 and the thickness of the wood sheet can be appropriately adjusted as necessary.
