  In the present embodiment, as shown in FIG. 1B, the adhesive 10 is applied to the end surface 2 a of the wooden substrate 2 using the adhesive application member 3 formed of the roll 4.

  As the adhesive 10, a hot-melt type resin such as ethylene vinyl acetate resin, reactive urethane resin, polyolefin, or a room temperature curable resin such as urethane resin, epoxy resin, vinyl acetate resin, vinyl urethane resin, or the like is used. Can do. Hot-melt type resins are preferably used because they are easy to handle and have good water-stopping properties for decorative boards.

  The roll 4 of the adhesive application member 3 is pivotally supported around a rotation shaft 7 so as to be rotatable. The shape of the roll 4 is not particularly limited as long as the roll surface 4a can be rotated while being in contact with the end surface 2a of the wooden substrate 2, such as a columnar shape, a conical shape, or a truncated cone shape. In this embodiment, the roll 4 has a truncated cone shape, and a portion corresponding to the side surface of the truncated cone is a roll surface 4a.

  The material of the roll 4 is not particularly limited, such as a synthetic resin material, a rubber material, or a metal material, but it is preferable to use a material that is inexpensive and easy to process.

  When the adhesive 10 is applied to the end surface 2a of the wooden substrate 2 using such a roll 4, the wooden substrate 2 is installed so that the surface 2b side of the wooden substrate 2 is directed upward in the vertical direction. The roll 4 projects the base side portion of the roll surface 4a upward from the corner portion on the surface 2b side of the end surface 2a of the wooden substrate 2, but the roll surface is brought into a non-contact state with the corner portion. 4a is placed in contact with the end surface 2a of the wooden substrate 2 at the tip side. In the roll 4 having the truncated cone shape, the tip side refers to the small diameter side of the truncated cone, and the base side refers to the large diameter side of the truncated cone.

  A gap Q is formed between the surface 2 b side portion of the end surface 2 a of the wooden substrate 2 and the roll surface 4 a of the roll 4. In the present embodiment, the adhesive 10 is supplied to the roll 4 using the adhesive supply roll 8, and the adhesive 10 is supplied from the roll surface 4 a to the gap Q by rotating the roll 4.

  The shape of the adhesive supply roll 8 is not particularly limited as long as the adhesive can be supplied to the roll 4, such as a columnar shape, a conical shape, and a truncated cone shape. In this embodiment, the adhesive supply roll 8 has a truncated cone shape similar to that of the roll 4, and a portion corresponding to the side surface of the truncated cone is a roll surface 8a.

  The material of the adhesive supply roll 8 is not particularly limited, such as a synthetic resin material, a rubber material, or a metal material, but it is preferable to use a material that is inexpensive and easy to process.

  The adhesive supply roll 8 is disposed so that the roll surface 8a and the roll surface 4a of the roll 4 are opposed to each other at a portion located on the upper side in the vertical direction, and is rotatably supported around the rotation shaft 9. The rotating shaft 9 is formed to extend in a substantially horizontal direction. As long as the adhesive 10 can be supplied to the roll 4, the adhesive supply roll 8 may be disposed so that the roll surface 8 a abuts on the roll surface 4 a of the roll 4 or is disposed at a predetermined interval. Also good.

  An adhesive storage tank 11 that stores the adhesive 10 is installed below the adhesive supply roll 8.

  By rotating the adhesive supply roll 8, the adhesive 10 can be spread over the entire circumference of the roll surface 8 a of the adhesive supply roll 8, and the adhesive 10 can be carried to a portion located on the upper side in the vertical direction. The adhesive 10 carried to the portion located on the upper side in the vertical direction is supplied to the roll surface 4a of the roll 4 facing the roll surface 8a in that portion. The adhesive 10 supplied to the roll surface 4 a of the roll 4 is spread over the entire circumference of the roll surface 4 a of the roll 4 by rotating the roll 4, and the adhesive 10 can be supplied to the gap Q. Due to the contact between the adhesive 10 supplied to the gap Q and the surface 2 b side portion of the end surface 2 a of the wood substrate 2, the portion is applied with the adhesive 10. In this method, an adhesive is applied to portions other than the surface 2b side portion of the end surface 2a of the wood substrate 2, for example, the surface 2b near the end surface 2a of the wood substrate 2 or the back surface 2c side portion of the end surface 2a of the wood substrate 2 10 leaks can be reduced.

  The roll 4 is preferably installed so that the contact angle θ between the roll surface 4a and the end surface 2a of the wooden substrate 2 is, for example, about 1 to 5 °. By bringing the roll 4 into contact with the end surface 2a of the wooden substrate 2 at a contact angle θ within such a range, the adhesive 10 can be more effectively applied to the end surface 2a of the wooden substrate 2. Moreover, the leakage of the adhesive 10 to a portion other than the surface 2b side portion of the end surface 2a of the wood substrate 2 can be more effectively suppressed.

  The supply amount of the adhesive 10 from the adhesive supply roll 8 to the roll 4 can be adjusted by adjusting the rotation speed of the adhesive supply roll 8. For this reason, what is necessary is just to set the rotational speed of the adhesive supply roll 8 suitably so that the adhesive agent 10 may be apply | coated to the end surface 2a with the optimal application quantity.

  The roll 4 and the adhesive supply roll 8 are connected to each other by, for example, providing a gear on the rotary shafts 7 and 9 of the roll 4 and the adhesive supply roll 8 or on an extension thereof, and connecting the rotary shafts 7 and 9 through the gear Synchronous rotation is also possible. By this synchronized rotation, a certain amount of the adhesive 10 can be supplied from the adhesive supply roll 8 to the roll 4, and the adhesive 10 can be applied to the end surface 2 a of the wooden substrate 2 with a uniform coating amount.

  In applying the adhesive 10 to the end surface 2a of the wooden substrate 2, the wooden substrate 2 is fed out along the paper surface penetration direction of FIG. 1B, and the roll 4 is fed in the same direction as the feeding direction of the wooden substrate 2. Try to rotate. As a result, the adhesive 10 can be applied to the end surface 2a of the wooden substrate 2 over the entire length in the feeding direction.

  In this way, as shown in FIG. 1C, the wood substrate 2 in which the adhesive 10 is applied to the surface 2b side portion of the end surface 2a of the wood substrate 2 is obtained.

  Next, the wooden substrate 2 is turned upside down. That is, the wood substrate 2 is installed so that the surface 2b side of the wood substrate 2 faces downward in the vertical direction. The roll 4 projects the base side portion of the roll surface 4a above the corner portion on the back surface 2c side of the end surface 2a of the wooden substrate 2, but the roll surface so as to be in a non-contact state with this corner portion. 4a is placed in contact with the end surface 2a of the wooden substrate 2 at the tip side. Next, the adhesive 10 is applied to the back surface 2c side portion of the end surface 2a of the wood substrate 2 in the same manner as the application of the adhesive 10 to the surface 2b side portion of the end surface 2a of the wood substrate 2 described above. As a result, as shown in FIG. 1 (d), the wood substrate 2 in which leakage of the adhesive 10 to the front surface 2 b and the back surface 2 c is suppressed is obtained. In the present embodiment, the adhesive 10 is applied to the front surface 2b side portion and the back surface 2c side portion of the end surface 2a of the wood-based substrate 2, and as a result, the adhesive 10 is applied to the entire end surface 2a. However, such a state is not necessarily required. For example, there may be a portion where the adhesive 10 is not applied between the front surface 2b side portion and the back surface 2c side portion of the end surface 2a of the wooden substrate 2.

  Next, as shown in FIG. 1 (e), the decorative material 5 is disposed on the end surface 2 a of the wooden substrate 2 via the adhesive 10. Examples of the decorative material 5 disposed on the end surface 2a of the wooden substrate 2 include a synthetic resin sheet such as vinyl chloride resin and polyurethane, a single plate, MDF, and the like. In addition, the same kind of the decorative material 6 arrange | positioned on the surface 2b of the wooden board | substrate 2 is mentioned.

  In this way, the decorative board 1 in which leakage (exposure) of the adhesive 10 to the front and back surfaces is suppressed is obtained. The obtained decorative board 1 can be used for, for example, a door of a system kitchen, a washstand, and the like.

  As described above, in the method according to the present embodiment, the saw blade groove forming step is not required as in the method of Patent Document 1, and the mold release agent applying step and the adhesive are performed as in the method of Patent Document 2. The decorative board which suppressed the exposure of the adhesive agent to front and back can be obtained, without requiring a removal operation | work. Therefore, the method of this embodiment is a simple method.

  While the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. For example, when applying an adhesive to the end surface of a wooden substrate, first, the adhesive is applied to the back side portion of the end surface of the wooden substrate, and then the adhesive is applied to the surface side portion of the end surface of the wooden substrate. it can. Also, a part of the roll surface of the adhesive supply member consisting of rolls is immersed in the adhesive in the adhesive storage tank, and the adhesive is spread over the roll surface by rotating the roll, and the adhesive is applied to the end surface of the wooden substrate.
