The second trim material 1b is made of resin parts 3, 3
a is fixed to the base material 2 by the fixing material layers 7 and 7a over almost the entire area, and therefore the base material 2 and the resin portions 3 and 3a swell.
No peeling or the like occurs.

In the manufacturing method described above, even when the boundary 4b between the changing portion 4 and the common resin forming portion 6 is at a position not suitable for forming a cut by the cutter 23, the formation of the cutout 3c allows the resin portion 3a to be formed. Peeling can be easily performed. In the above embodiment, the cut 3d is formed by the cutter 23 at the boundary 4a on the outer surface side. However, the cutout 3c may be formed at this portion.

FIGS. 10A and 10B are partial cross-sectional views showing a trim material according to another embodiment. In (a), a convex portion 2a is formed on the base material 2 at a boundary portion 4b, thereby forming a missing portion 3c at the boundary between the resin portions 3 and 3a. Further, in FIG. 2B, the cutout 3c is a complete cutout, and the resin portions 3, 3a do not exist in this cutout. In any case, the resin portion 3a is peeled off in substantially the same manner as in the above embodiment.

In the above embodiment, the fixing material layers 7, 7a
However, the adhesion may be provided by corona discharge or other means, which is one of the plasma treatments. The configuration of the sticking device 18 can be selected according to these sticking devices. Further, the sticking device 18 may be provided before the roll forming machine 16.

The cutter 23 is preferably provided immediately after the extrusion mold 22 to make a cut when the resin is still soft at a high temperature. However, even if the cutter 23 is provided before and after the take-off machine 25 and the resin is cooled, the cutter 23 may be provided. Alternatively, the cutting may be performed in a separate step after the first trim material is cut to a predetermined length by the cutting machine 26.

The peeling of the strippable tape 13 is not limited to the position shown in the drawing, and the material is not softened or melted so as to have an adverse effect even when it passes through an extruding mold heated by a heat-resistant tape. In this case, the resin part 3a is formed after extrusion molding.
At the same time, it can be peeled and removed. Further, a tape wider than the width of the change portion 4 is pasted as the peelable tape 13 in advance, and an extra portion is peeled off, leaving a necessary width corresponding to the width of the change portion 4. Is also good.

In addition, in the above-described embodiment, the example of the extrusion mold 22 is shown as the mold, but an injection mold, a compression mold, or the like may be used. In these cases, after the base material 2 is cut into a predetermined size, The resin parts 3, 3a are molded by being introduced into a molding die. In addition, as the base material, an aluminum alloy deformed extruded material cut in advance to a predetermined length can be used,
In this case, the roll forming machine 16 and the cutting machine 26 in FIG. 2 are omitted.

In the above description, the trim material is
Not only the trim material shown in FIG. 1 but also the trim materials shown in FIGS. 11A to 11F and other trim materials can be manufactured in the same manner. Further, the present invention is not limited to vehicles, and can be applied to the manufacture of trim materials for other uses.
