善の余地が多分にあつた。 Traditionally, drum bodies have been made of wood, but recently resin laminates have also come into use. This involves wrapping a prepreg (resin-impregnated) resin base material, mainly made of paper, woven fabric, glass fiber, etc. and using thermosetting resin as a binder, around a mandrel with an outer diameter corresponding to the inner diameter of the required drum body. It is a cylindrical product obtained by laminating the resin under heat and pressure, and then curing the resin. However, the surface of the material at this time is not smooth and has defects in color tone, gloss, etc., so it is difficult to paint the surface. Methods have been adopted to enhance the sense of beauty. However, such a method of painting the surface of a laminated cylinder requires considerable effort and time, and there is much room for improvement.

述べる。 This invention was made with attention to the current situation, and in the process of manufacturing thermosetting resin laminated tubes, metal is added to the outermost layer in the process of winding and laminating thermosetting resin prepreg base materials. The present invention provides a method for manufacturing a drum body characterized by stacking thin plates and curing them under heat and pressure. The details are described below.

つても何等支障はない。 The base material constituting the thermosetting resin laminate tube in the present invention is, for example, a paper material such as kraft paper, linter paper, or a mixed paper thereof, a woven or nonwoven fabric made of organic or inorganic fibers,
The thermosetting resin used as the binder may be any of commonly used resins such as phenol resin, epoxy resin, polyester resin, and melamine resin. There is no problem.
このような素材から積層管を製造する方法は、

のであつてもよい。また、金属製薄板５の厚さは
積層円筒４の外周面にある程度容易に巻取れるも
のであればよく、通常0.1mm前後またはそれ以下
が望ましい。 The method of manufacturing laminated pipes from such materials is as follows:
The conventional method can be used as is. For example, a mandrel 2 of the required size is brought into contact with a heating pressure roller 1 as shown in the figure, a thermosetting resin prepreg base material 3 is inserted between the two, and the mandrel 2 is heated and pressed. It is wound around the outer periphery to form a laminated cylinder 4. Therefore, in the present invention, if we take the method shown in the figure as an example, a thin metal plate 5 is continuously inserted at the final edge of the thermosetting resin prepreg base material 3, and the laminated cylinder 4 is Wrap around the outer surface (usually single layer)
Then, the entire laminated tube is completely cured while the laminated cylinder 4 is cured by heating and pressure and the thin metal plate 5 is fixed. Here, the thin metal plate 5 may be made of substantially pure metal or an alloy, and may be subjected to various surface treatments (for example, chemical etching, oxidation, electrochemical plating, etc.). , oxidation, polishing, etc., or physical vacuum deposition, ion plating, graining, etc.). Further, the thickness of the metal thin plate 5 may be such that it can be wound around the outer circumferential surface of the laminated cylinder 4 with some degree of ease, and it is usually desirable to have a thickness of around 0.1 mm or less.
このようにして積層円筒４を金属製薄板５で覆
つて一体成形および熱硬化を終わつた熱硬化性樹
脂積層管はマンドレル２を抜取り、所要の長さに
適宜寸法を調整すれば、所望の太鼓胴が得られ

は、前記したように積層円筒４に巻付ける以前の
薄板に予め行なつておいてもよいが、積層円筒４
に巻付け加熱加圧成形した後、または寸法の最終
調整後に行なつてもよいことは勿論であつて、こ
の発明の方法によれば寸法や色彩等のきわめて変
化に富んだ金属被覆太鼓胴が容易に得られるの
で、この発明の意義は大きいと言うことができ
る。 The thermosetting resin laminated tube, which has been integrally molded and thermoset by covering the laminated cylinder 4 with the metal thin plate 5 in this way, can be made into a desired drum by removing the mandrel 2 and adjusting the dimensions to the required length. A torso is obtained. The surface of the metal thin plate 5 may be treated or processed in advance before it is wrapped around the laminated cylinder 4 as described above.
It goes without saying that this process may be carried out after wrapping and heating and press-forming, or after final adjustment of dimensions, but the method of the present invention allows metal-coated drum bodies with a wide variety of dimensions, colors, etc. to be formed. Since it can be easily obtained, it can be said that the significance of this invention is great.
