備え九彎曲積層材製品を製造してい友。(Prior Art) The above-mentioned conventional curved laminate material was manufactured by the manufacturing method shown in FIG. That is, a pair of a mold 1 having a convex curved surface and a mold 1 having a front curved surface facing it are prepared, and a flat sound absorbing material C is inserted between these molds (Fig. 1). From this state, both molds 111 are closed and the flat sound absorbing material O is sandwiched and curved between the facing front curved surface and the convex curved surface to form a curved sound absorbing material C'. Open the molds &, b, insert the skin material d between them, and apply the adhesive d to the concave surface of the curved sound absorbing material O/ (Fig. 1 0).
In this state, both molds a and b are closed, and the skin material d is pressure-polymerized on the curved sound-absorbing material 0', and the skin material d is curved and pasted on the concave surface of the curved sound-absorbing material a/ to form a concave curve. Our company manufactures nine-curved laminated material products with skin material & I on the face side.

いたものを使用することは云うまでもない。This curved laminated material is used as an interior material for a soundproof box to be applied to the curved wall surface of a cylindrical body with a concave surface such as a large gas regulator. Needless to say, a concave mold and a convex mold having the following characteristics are used, which have been prepared in advance.

。(Problems to be Solved by the Invention) According to the manufacturing method listed in all above, when the sound absorbing material 0 is the curved sound absorbing material O', wrinkles, cracks, etc. often occur on the surface of the curved sound absorbing material O'. As a result, unevenness occurs on the surface of the skin material adhered to the concave surface, often resulting in defective products with wrinkled surfaces. In order to prevent this drawback, it can be improved by interposing a cushion layer capable of absorbing irregularities between the sound absorbing material and the skin material, but this requires time and effort to manufacture and increases product cost. According to the second manufacturing method mentioned above, since the molding temperature is as high as 150 to 250°C, there is a drawback that only heat-resistant materials can be used.

Prepare the front curved surface (1a) K of 1) in a fixed state, and attach the flat sound absorbing material 141 to the curved skin material (2) side from one end along the curved surface of the skin material (2 pi). I decided to do this, so
Curved skin material 12+'K A good product can be obtained without any wrinkles or cracks. As the skin material (2), any material can be used, such as glass non-woven fabric, cotton woven fabric, non-woven fabric, synthetic resin leather, etc., but non-woven fabric has a particularly strong absorption effect on the uneven surface of the sound absorbing material, and has a strong repulsive force. has
It can be used preferably because it has the property of stretching out wrinkles and folds. As the sound absorbing material +4), any material can be used depending on the purpose, such as a foam molded synthetic resin molded plate or an inorganic fiber molded body (glass wool), but in particular, fine fiber glass wool is used to attenuate noise in the high frequency range. Particularly preferred.

要に応じ加熱ができるようにしてもよい。In the illustrated embodiment, the skin material (2) is made of a glass fiber nonwoven fabric, and the sound absorbing material 147 is made of a molded mat made of fine glass fibers. According to the present invention, the nine-curved calendar material released from the jig 111 surprisingly retains its curved shape and does not return to a flat plate. This seems to be because the length of the concave curved surface side of the curved skin material of the laminated material is different from the length of the convex end curved surface side of the sound absorbing material. As is clear from the above, according to the present invention,
Unlike conventional methods, there is no need to make a pair of concave and convex molds, and the above-mentioned simple equipment is sufficient. Also, there is no need for hot-pressure molding, so jig (1) It does not necessarily have to be made of metal; it may be made of wood or synthetic resin, and can be manufactured at low cost. Of course, the jig (11) may be made with a mold so that it can be heated as necessary.

Since the polymer is adhered to the surface of the convex curved skin material, it is possible to reliably obtain a good curved laminate material that does not cause wrinkles or cracks on the surface of the curved skin material, and it is easy to manufacture and can be manufactured at a relatively low cost. have an effect.
