Then, the trimming head 41 moves along the surplus end portion S on the leading end side in the conveying direction P of the decorative material 9 and then moves along the surplus end portion S on the rear end side in the conveying direction P of the decorative material 9 ( (See FIG. 14). During the movement of the trimming head 41, the rotating cutter 48 removes the excessive end portion S of the decorative material 9 while the outer ring 52 of the bearing 50 rolls on the outer peripheral surface of the base material 8. At this time, the adhesive protruding from the back surface 9a side of the decorative material 9 together with the excessive end portion S of the decorative material 9 is removed (see FIG. 14). As a result, the decorative material 9 is chamfered according to the outer diameter shape of the substrate 8, and the coated product W (see FIG. 10) is obtained.

(3) Effects of Embodiment As described above, according to the trimming device 6 for the decorative material of the present embodiment, the trimming head 41 that moves along the surplus end portion S of the decorative material 9 is provided. A rotary cutter 48 connected to the drive shaft 47a of the drive motor 47 to remove the excessive end S of the decorative material 9, an attachment member 49 attached to the axial center side of the rotary cutter 48, and a rotary cutter on the attachment member 49 And an outer ring 52 of a bearing 50 that is rotatably supported around the axis of 48 and rolls on the substrate 8. Thereby, when the trimming head 41 moves along the surplus end portion S of the decorative material 9, the rotary cutter 48 rotates on the base material 8 while the bearing 50 outer ring 52 rolls on the surplus end portion S of the decorative material 9. And the decorative material 9 is chamfered. Since the outer ring 52 of the bearing 50 is supported by an attachment member 49 attached to the rotary cutter 48 so as to be rotatable about the axis of the rotary cutter 48, the axis between the outer ring 52 of the bearing 50 and the rotary cutter 48 is supported. Is positioned accurately. As a result, it is possible to suppress chamfering of the outer ring 52 of the bearing 50 with respect to the base material 8 and accurately remove the excess end portion S of the decorative material 9 to be chamfered. In particular, according to the present embodiment, even if the excessive end portion S of the decorative material 9 is formed in a reverse taper shape, the excessive end portion S of the decorative material 9 can be accurately removed and chamfered.

  In the present embodiment, the trimming head 41 includes a pressure contact piece 57 that is in pressure contact with the outer peripheral surface of the outer ring 52 of the bearing 50. The pressure contact piece 57 is in pressure contact with the outer peripheral surface of the outer ring 52 of the bearing 50, thereby preventing rotation of the outer ring 52 of the bearing 50 with the rotary cutter 48 and cutting chips on the outer peripheral surface of the outer ring 52 of the bearing 50. Of foreign matter can be prevented.

  Further, in this embodiment, the rotary cutter 48 of the trimming device 6 for decorative material includes a tip blade 62 with a reverse lead that feeds cutting waste toward the outside of the decorative surface 9 b of the decorative material 9. Thereby, when the rotary cutter 48 removes the excessive end portion S of the decorative material 9, the adhesive protruding to the back surface 9 a side of the decorative material 9 can be easily removed, and the generation of burrs can be suppressed. Furthermore, in this embodiment, the leading edge of the rotary cutter 29 of the trimming unit 5 is also a reverse lead, so that it exhibits substantially the same operations and effects as the rotary cutter 48.

  In this embodiment, the decorative material bonding apparatus 3 applies the adhesive material 10 to the back surface 9a of the decorative material 9 fed toward the end surface 8a of the base material 8 conveyed in the predetermined conveying direction P. 17, and a pressing portion 18 that presses the back surface 9 a of the decorative material 9 to which the adhesive material is applied by the applying portion 17 against the end surface 8 a of the base material 8. Thereby, the space | interval of the application part 17 and the press part 18 becomes comparatively small, and the time from application | coating of an adhesive agent to adhesion | attachment of the base material 8 and the decorative material 9 becomes short. As a result, it is possible to bond the base material 8 and the decorative material 9 without strictly controlling the temperature of the base material 8 while suppressing processing costs. Further, by the trimming device 6 for the decorative material described above, when the rotary cutter 48 removes the excessive end portion S of the decorative material 9, the adhesive that protrudes from the back surface 9 a side of the decorative material 9 can be easily removed.

Therefore, the application portion 17 is relatively thin (for example, thick). Even if the decorative material 9 having a thickness of 0.5 mm or less is employed, the base material 8 and the decorative material 9 can be reliably bonded. Moreover, the transfer of the adhesive material 10 to the surface side of the base material 8 is suppressed, and an excessive portion of the adhesive material 10 can be easily removed in a subsequent process. On the other hand, when the adhesive is applied to the end surface of the base material and the base material and the decorative material are adhered to each other as in the prior art, the adhesive material easily transfers to the surface side of the base material, and the surplus of the adhesive material in the subsequent process The removal work of the end becomes complicated.

  Further, in the present embodiment, the application unit 17 is disposed opposite to the application nozzle 20 having a slit-like application port 20a for applying the adhesive material 10 and the application material 20 with the decorative material 9 interposed therebetween, and the application nozzle. And a pressing roller 21 that presses the decorative material 9 toward 20. Thereby, the application part 17 can be reduced in size. Therefore, the space | interval of the application part 17 and the press part 18 becomes shorter, and the adhesiveness of the base material 8 and the decorative material 9 can be improved more.
