A notch C2 extending corresponding to the other end is formed.

    Note that 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 material 1 with a cutting line parallel to the lowest portion (the most depressed portion) of the groove 3. . Moreover, in this embodiment, since the groove | channel 3 is formed in the center of the width direction of the base material 1, it cut | disconnects the center of the width direction of the said sheet | seat 20 'to the vertical direction (longitudinal direction of the base material 1), and the said. The sheet 20 ′ may be divided into two.

    Although details will be described later, by forming the cut C1 in the second sheet cutting step in this manner, the floating of the groove inner surface portions 20d and 20d can be suppressed when the third sheet bonding step is performed. In addition, by forming the cut C2 in the second sheet cutting step, the second sheet bonding step can be easily performed.

(8) Second sheet bonding step (lamination in the groove)
In the second sheet adhering step (groove inner surface adhering step), as shown in FIGS. 8A and 8B, the portion located above the groove 3 of the sheet 20 ′ is bent and pressed to the inner surface of the groove 3; Adhesive is solidified and bonded.

    In the present embodiment, the second sheet adhering step is performed using a pressure-bonding roll in which an annular convex portion having a cross-sectional shape equal to the cross-sectional shape of the groove 3 is formed on the outer peripheral surface. Specifically, a convex portion of the pressure roller presses a portion located above the groove 3 of the sheet 20 'against the inner surface (two inclined surfaces 3a) of the groove 3, and is applied to the back surface of the sheet 20'. By solidifying the adhesive, the portion located above the groove 3 of the sheet 20 ′ is bonded to the inclined surfaces 3 a and 3 a 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 material 1.

By clamping and pinching the protruding portion 21 ′ (both excess portions), the side surface portion 20 b and the end side surface portion 20 c of the two sides of the decorative sheet layer 20 overlap the back surfaces of the protruding portion 21 ′. Mold to be in a state. For example, at each of the four corners of the base material 1, each protruding portion 21 ′ is formed such that each protruding portion 21 ′ is oriented in a direction that forms an angle of 135 ° with two adjacent sides. .

(11) Excessive part excision process In the extra part excision process, as shown in FIGS. 11A and 11B, each protruding portion 21 ′ of the sheet 20 ′ is excised at the middle part of the base material 1. . Thereby, both the surplus parts of the side side surface part 20b and the end side surface part 20c of the decorative sheet layer 20 are simultaneously excised while being overlapped, and the excised part 21 is formed.

(12) Corner portion forming step In the corner portion forming step, each of the cut portions 21 is softened by heating so as to conform to the outer surface of the substrate 1. In this step, for example, the heated plate is pressed against the excision part 21 and heated, so that the excision part 21 is brought into a molten state so as to conform to the outer surface of the substrate 1. In addition, in this corner | angular part shaping | molding process, you may heat to the extent to which each cutting part 21 (decorative sheet layer 20) melt | dissolves partially, and the cut surfaces are heat-sealed.

    By passing through the above process, the said wrapping decorative board A is obtained.
