[0002]

2. Description of the Related Art Cars, buses, trucks, motorcycles,
As a trim material for vehicles such as electric trains, there is a material in which a resin portion such as rubber or synthetic resin is formed on a long base material such as a bright stainless steel plate. FIG. 1 shows a trim member used as a vehicle molding, (a) is a perspective view, and (b) is an enlarged sectional view thereof.

In FIG. 1, reference numeral 1 denotes a trim material, which is a deformed material such as a stainless steel plate or an extruded aluminum alloy material. It is laminated and fixed via a fixing material layer 4 such as a contact (adhesive). In such a trim material 1, a decorative tape 6 is attached by a fixing material layer 7 such as a contact (adhesive) adhesive, with a part of the outer surface on which the resin portion 3 is not formed as a different color portion 5.
The side edge portion is covered with the resin portion 3.

As a method of manufacturing such a trim material 1,

[0005]

However, in such a conventional method for manufacturing a trim material, the base material 2 to which the decorative tape 6 is adhered is introduced into the extrusion molding die, and the resin portion 3 is formed.
When the extrusion molding is performed, the decorative tape 6 is affected by the heat of the molten resin to be extruded and softened and stretched, or the surface is damaged. Therefore, the material that can be used as the decorative tape 6 is limited to a material having high heat resistance such as metal foil, and there is a problem that a material having low heat resistance such as some synthetic resin tape cannot be used.

In order to solve the above problems, the object of the present invention is to use a material having a relatively low heat resistance, which makes it possible to manufacture various types of trim materials having different color portions. It is to propose a method and an apparatus for manufacturing a trim material.
