(2) Film Layer Forming Step In the film layer forming step, the paint is applied to the inner surface of the groove 3 formed in the cutting process, and the inner surface of the groove 3 is covered with the coating layer 10 (see FIG. (B) (black) is formed.

(3) Adhesive Application Step In the adhesive application step, an adhesive (a moisture-curable urethane resin-based hot melt adhesive) is applied to the back surface of the sheet 20 ′. The adhesive may be applied to the surface 1a (including the groove 3) and the side surfaces 1b and 1c (including the chamfered portion 2) of the base 1 instead of the application to the back surface of the sheet 20 '.

The sheet 20 ′ is, for example, wound around a roll or the like and continuously fed from the roll or the like and supplied, and the width of the sheet 20 ′ is lapped to the base 1 in advance. It may be set to a reference width corresponding to or may be larger than the reference width. Specifically, the reference width of the sheet 20 'is such that the sheet 20' is lapped with the substrate 1 in the same width direction, and the peripheral portion of the sheet 20 'is obtained in the (5) first sheet bonding step described later. When bent, the tip of the bent peripheral edge portion has a width such that it does not reach the female actual concave portion 5 and the male actual convex portion 13 on the side side surfaces 1 b and 1 b of the base material 1. FIG. 5A shows a sheet 20 'of the reference width.

(4) Sheet Surface Bonding Step In the sheet surface bonding step (surface bonding step), the sheet 20 ′ is bonded to the surface 1a of the substrate 1 with an adhesive as shown in FIGS. 5 (a) and 5 (b). At this time, the sheet 20 'and the substrate 1 are precisely aligned in the width direction and adhered. By this operation, the surface portion 20 a of the decorative sheet layer 20 is formed on the surface 1 a of the substrate 1.

(5) First sheet bonding process (side laminate)
In the first sheet bonding step (second side bonding step), as shown in FIGS. 6 (a) and 6 (b), the peripheral portions on both sides in the width direction of the sheet 20 'are bent to form the chamfered portion 2 of the substrate 1. Then, pressure is applied to the projecting end face of the front side female real convex portion 6 of the female real 4 on the side side surfaces 1b and 1b and the bottom surface of the front side male real concave portion 14 of the male 12 to solidify and bond the adhesive.

In the present embodiment, the first sheet bonding step is performed using a plurality of pressure bonding rollers provided such that the pressure bonding surface is arranged along the outlines of the chamfered portion 2 and the side surfaces 1b and 1b of the base material 1. Specifically, while pressing the peripheral portions on both sides in the width direction of the sheet 20 'by the plurality of pressure-bonding rollers, they are pressed against the chamfered portion 2 and the side surfaces 1b and 1b of the base material 1 to the back surface of the sheet 20'. By solidifying the applied adhesive, the peripheral portions on both sides in the width direction of the sheet 20 'are adhered to the chamfered portion 2 and the side surfaces 1b and 1b of the substrate 1. By this operation, the

side surface portions

20 b and 20 b of the decorative sheet layer 20 are formed on the

side surface

1 b and 1 b of the base material 1 and the chamfered portion 2.

The first sheet bonding step is not limited to the above-described one using the pressure roller. For example, with the use of a heated bending jig, the peripheral portions on both sides in the width direction of the sheet 20 'are pressed against the chamfered portion 2 and the side surfaces 1b and 1b of the substrate 1 to reactivate the adhesive on the back surface of the sheet 20'. After performing the hot press operation to make it remelt (remelt), the peripheral edge of the both sides in the width direction of the sheet 20 'is made to the chamfer 2 of the base material 1 and the

side surface

1b, 1b A cold press operation may be performed in which the pressed and reactivated adhesive is solidified by cooling and adhered.

(6) First sheet cutting process (end cut)
In the first sheet cutting step, in the peripheral portion of the sheet 20 ′, a portion corresponding to the two sides of the end side surfaces 1 c and 1 c in the base 1 facing each other in the longitudinal direction is the end side of the base 1. When it is bent into 1c and 1c, it is cut so as to have a predetermined length so as not to reach the female actual recess 5 and the male actual protrusion 13 via the chamfered portion 2. In this cutting, for example, the front end of the substrate 1 is detected by a sensor, and the substrate 1 is cut at the predetermined length according to the total length of the continuously transported substrate 1.

(7) Second sheet cutting process (groove cut)
In the second sheet cutting step (cutting step), as shown in FIGS. 7 (a) and 7 (b), above the groove 3 of the sheet 20 'not adhered to the surface 1a of the substrate 1 by the sheet surface bonding step. From the position corresponding to both ends of the bottom (the most recessed part) of the groove 3 to the located part, a cut C1 extending from the position corresponding to both ends of the bottom of the groove 3 to the end edge of the sheet 20 'and one end of the lowest part (the most recessed part) of the groove 3 A cut C2 is formed corresponding to the other end.

The two cuts C1 and one cut C2 are continuous on a straight line on the sheet 20 '. Therefore, the cuts C1 and C2 are formed by cutting a portion of the sheet 20 'located on the groove 3 of the base 1 at a cutting line parallel to the lowest portion (the most recessed portion) of the groove 3 . Further, in the present embodiment, since the groove 3 is formed at the center in the width direction of the substrate 1, the center in the width direction of the sheet 20 'is cut in the longitudinal direction (longitudinal direction of the substrate 1). The sheet 20 'may be divided into two.

Although details will be described later, by forming the cut C1 in the second sheet cutting process in this way, it is possible to suppress the floating of the groove

inner surface portions

20d, 20d when performing the third sheet bonding process. Further, by forming the cuts C2 in the second sheet cutting process, the second sheet bonding process can be easily performed.

(8) Second sheet bonding step (lamination in groove)
In the second sheet bonding step (groove inner surface bonding step), as shown in FIGS. 8A and 8B, the portion of the sheet 20 ′ located above the groove 3 is bent to press the inner surface of the groove 3 and Solidify and bond the adhesive.

In the present embodiment, the second sheet bonding step is performed using a pressure bonding roll in which an annular convex portion having a cross-sectional shape equal to that of the groove 3 is formed on the outer peripheral surface. Specifically, a portion of the sheet 20 'located above the groove 3 is pressed against the inner surface (two inclined surfaces 3a) of the groove 3 by the convex portion of the pressure roller, and is applied to the back surface of the sheet 20'. By solidifying the adhesive, the portion of the sheet 20 'located above the groove 3 is adhered to the

inclined surfaces

3a and 3a of the groove 3 of the substrate 1. By this operation, groove

inner surface portions

20 d and 20 d of the decorative sheet layer 20 are formed on the inner surface of the groove 3 of the base 1.

In the present embodiment, by performing the second sheet cutting process before the second sheet bonding process, the cuts C2 are formed in the portions of the sheet 20 ′ located on the grooves 3 of the base 1. Therefore, when pressing a portion of the sheet 20 'located on the groove 3 of the base material 1 against the inner surface (two

inclined surfaces

3a, 3a) of the groove 3, the sheet 20' is stretched by applying an unreasonable force. Instead, the sheet 20 'can be attached cleanly to the inner surface of the groove 3 simply by bending the sheet 20' along the upper end edge of the groove 3 and pressing the sheet 20 'onto the

inclined surfaces

3a and 3a.

(9) Third sheet bonding process (end lamination)
The third sheet bonding step (first side bonding step) is also basically the same as the first sheet bonding step, and bonds the peripheral portions on both sides in the length direction of the sheet 20 ′ cut in the sheet cutting step. Only That is, in this step, as shown in FIGS. 9A and 9B, the peripheral portions on both sides in the length direction of the sheet 20 ′ cut in the second sheet cutting step are bent to chamfer the substrate 1 The pressure is applied to the protruding end surface of the front side female real convex portion 6 of the female real 4 at the end 2 and the end side surfaces 1c and 1c and the bottom surface of the front side male real concave portion 14 of the male 12 and the adhesive is solidified and adhered. By this operation, the end

side surface portions

20 c and 20 c of the decorative sheet layer 20 are formed on the end side surfaces 1 c and 1 c of the base 1 and the chamfered portion 2.

In the present embodiment, by performing the second sheet cutting step before the second sheet bonding step, the peripheral portion of the sheet 20 ′ corresponds to the both end portions of the bottom portion (the most recessed portion) of the groove 3. Notches C1 are formed extending from the position to the edge of the sheet 20 '. Therefore, after the sheet 20 'is adhered to the inner surface of the groove 3 of the base 1 by having such a cut C1 in the peripheral part of the sheet 20', the peripheral part of the sheet 20 'is bent in the third sheet bonding step. At the same time, the groove bottom portion of the sheet 20 ′ adhered to the inner surface of the groove 3 is not subjected to a force for lifting the groove bottom portion above the groove. Therefore, without making the groove inner surface portion 20d of the decorative sheet layer 20 adhered to the inner surface of the groove 3 float from the inner surface of the groove 3, the two end side surfaces 1c and 1c provided with the end of the groove 3 of the substrate 1 Can be precisely wrapped with the sheet 20 '.

When this second sheet bonding step is completed, the peripheral portions of the sheet 20 'are bonded to the two

side surfaces

1b and 1b and the two end side surfaces 1c and 1c of the substrate 1, and the

side surface portions

20b and 20b and End

side surface portions

20c, 20c are formed. In addition, extraneous portions of the side side surface portion 20b and the end side surface portion 20c of the decorative sheet layer 20 are gathered at four corner portions of the base material 1 to form a protruding portion 21 ' Be done.

It is molded to be in a state. For example, in each of the four corner portions of the substrate 1, each protrusion 21 'is formed such that each protrusion 21' is oriented in a direction forming an angle of 135 ° with respect to two adjacent sides. .

(11) Surplus Portion Excising Step In the surplus portion excising step, as shown in FIGS. 11 (a) and (b), the respective exudation portions 21 ′ of the sheet 20 ′ are excised at the front and rear of the base material 1 . As a result, both surplus portions of the side side surface portion 20b and the end side surface portion 20c of the decorative sheet layer 20 are cut at the same time in the overlapping state, and the cut portion 21 is formed.

(12) Corner Forming Step In the corner forming step, the cut portions 21 are softened by heating to conform along the outer surface of the substrate 1. In this step, for example, the heating plate is pressed against the cutting portion 21 and heated, whereby the cutting portion 21 is melted and conformed along the outer surface of the substrate 1. In this corner portion forming step, each cut portion 21 (the decorative sheet layer 20) may be partially melted and heated to such an extent that the cut surfaces thereof are thermally fused.

By passing through the above steps, the above-mentioned wrapping decorative board A is obtained.
