Description

Board sheet attaching method using a board sheet attaching device}

The present invention relates to a method of attaching a board sheet using a board sheet attachment device, and more specifically, to a method of attaching a board sheet using a board sheet attachment device implemented to improve the efficiency of attaching the sheet to a wooden board.

A sheet attachment device is a device that attaches a sheet to a common board-shaped plywood material. When sheets are attached to plywood, deformation of the material can be prevented and the appearance of the material can be improved in various ways, so it is widely used in the interior and exterior construction field.

However, since this prior art uses simple cylindrical rollers to press the material and sheet, precise and reliable pressurization becomes difficult when the surface shape of the material is complex, and as a result, the adhesion effect in specific parts of the material is reduced. Falling problems may occur.

For example, in the case of construction plywood, a three-dimensional surface is expressed by forming geometrically uneven surfaces or depressed spheres on the plywood surface for interior effects. In this case, when sheets are simply attached to the surface of the plywood using cylindrical rollers, Right, there is a problem in that the sheet cannot be pressed to the detailed parts of the plywood, so the sheet cannot be firmly attached to the plywood and a lifting phenomenon occurs.

Meanwhile, the above-mentioned background technology is technical information that the inventor possessed for deriving the present invention or acquired in the process of deriving the present invention, and cannot necessarily be said to be known technology disclosed to the general public before filing the application for the present invention. .
