Description

Method for producing lapping decorative board

The present invention relates to a method for producing a wrapping decorative board in which a decorative sheet layer is formed on a surface by integrally bonding a sheet to a plate-like substrate.

Conventionally, for example, a method disclosed in Patent Document 1 is known as a method for producing a wrapping decorative board.

Patent Document 1 discloses a rectangular plate-like base material, which has a male on one side on the long side or one side on the long side and one side on the short side, and a female on the other side. There is disclosed a method for manufacturing a sheet wrapping product comprising a base material having one sheet and a sheet attached to at least a region adjacent to the top surface of the entire top surface and four side surfaces of the base material.

JP 2008-142976 A

In the manufacturing method disclosed in Patent Document 1, as a pre-process for attaching a sheet to the peripheral side surface of the base material, it is applied to the four side surfaces of the base material in a region outside the top surface of the sheet attached to the top surface of the base material. A stamping step is included in which four notch portions each having four corners of the top surface of the base material as apexes are formed on the peripheral edge portion of the sheet by the punching die so as to form side-separated pieces separated from each other. Yes. That is, in the punching process in this manufacturing method, a large-scale device such as a punching die must be used in order to preliminarily form a cutout portion in the peripheral edge portion of the sheet. It is not envisaged that a notch is formed in the peripheral edge of the sheet while the sheet is aligned with the shape of the side edge on the side surface of the substrate using pliers or the like.

In addition, in such a method in which a notch portion is previously formed in the peripheral edge portion of the sheet by a punching die, it is difficult to prevent an error between the processing accuracy of the notch portion and the processing accuracy of the base material. There is a problem that, if a large error has occurred, each side sticking piece of the sheet after the punching process cannot be attached cleanly to the four side surfaces of the base material (particularly, each corner portion of the base material). It was.

The present invention has been made in view of such points, and an object of the present invention is to use a general-purpose tool (scissors) without forming a notch portion in the peripheral portion of the sheet in advance using a large-scale apparatus using a punching die. And pliers, etc.) to easily and cleanly wrap the sheet from the surface of the base material to each side surface or front side surface of the male and female.

In order to achieve the above object, according to the present invention, before bonding the sheet to each side or front side of the male and female in the base material, a notch is formed in the peripheral edge of the sheet, and the notch is used as a reference. The sticking part was formed.

A method for producing a wrapping decorative board comprising a decorative sheet layer made of a sheet bonded and integrated over a side surface or a front side surface continuous with a material surface, the sheet surface bonding step for bonding the sheet to the surface of a substrate; A plurality of side portions are divided into the peripheral portion of the sheet by forming a cut portion in the peripheral portion of the sheet bonded to the substrate surface from the peripheral portion to the apex of each corner portion on the surface of the substrate. A region surrounded by a notch process and a bent portion corresponding to the shape of the side end of each side or front side of the male and female and the notch from both sides in the length direction of each side of the sheet Excision step of excising the surplus part consisting of Characterized in that it comprises a sheet side bonding step for bonding and integrating the respective bent portion of the sheet remaining after resection of the surplus portion over a side surface or front surface of each of the male and female fruit, a.

In this first embodiment, before performing the sheet side surface adhering step, the notch portion is formed in the notching step, and then the surplus portion including each notching portion is excised in the excision step. That is, by forming the cut portion in the sheet bonded to the surface of the base material first, the side portion of the sheet is divided and formed so as to correspond to each side surface or front side surface of the male and female. In addition, by cutting off the excess part from both sides of each side part to both sides of the cut part, the side ends of each folded part after the sheet side surface bonding step are butted against each other without overlapping each other It becomes possible to finish it neatly. As described above, in the first embodiment, the sheet can be removed by using a general-purpose tool (such as scissors or pliers) without previously forming a cutout portion at the peripheral edge of the sheet using a large-scale apparatus such as a punching die. It is only necessary to cut off the surplus part after forming the cut part in the peripheral part, and the sheet can be easily and cleanly wrapped from the surface of the base material to each side surface or front side surface of the male and female.

The second form is characterized in that, in the first form, in the first form, the cut part is formed in the sheet in a direction inclined by 45 degrees with respect to the sides on both sides of each corner part on the surface of the substrate.
