高密度フェルト円筒体の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a high-density felt cylindrical body capable of varying from a small diameter to a large diameter, which is used for a conveying roller of aluminum profile or the like. It relates to a manufacturing method.

For this reason, aluminum processing plants are equipped with conveyors such as drive conveyors, walking beam coolers, line-out tables, and lifting machines, and the extruded profile immediately after coming out of the die is first supported by multiple conveyor rollers. After this, it is sent to a predetermined carrier or post-processing facility. Immediately after being extruded from the die, the extruded shape member has a high temperature close to the melting point (660 ° C.) of aluminum, and thus the surface is damaged when it comes into direct contact with the roller surface. For this reason, a felt tube made of heat resistant fiber is fitted on the roller surface for cushioning. In addition, the heat-resistant rolls are also used for receiving rolled aluminum plates at aluminum processing plants and plated thin plates at steel processing plants.

The variation is low and the unit price is high. Further, if a laminated felt cylinder is manufactured by cutting a felt sheet into a disc shape, a large amount of cutting felt waste is generated from the sheet, which is uneconomical, and the cost of disposing of the felt waste is also required. On the other hand, in the roll manufacturing method disclosed in Japanese Patent Laid-Open No. 60-90673, although the material used can be saved, the cylindrical shape is easily deformed when the laminated body is compressed, so that it cannot be strongly compressed. Not durable enough.

Using the felt material 2, the reinforcing thread 4 is sewn straight along a side of the felt material with a sewing machine. The belt-shaped felt material 2 has various fiber webs integrated by needle punching to be about 0.5.
It may be cut from a felt sheet having a thickness of up to 4 mm, and a plurality of sheets may be polymerized, if desired, or the felt material may be sewn vertically to a predetermined length with a sewing machine. The fibers forming the felt material 2 may be appropriately selected according to the application.
One kind or two or more kinds of natural fibers, synthetic fibers or both are mixed and used. For example, for conveying rollers of aluminum profile,
Aramid fiber alone which is a heat resistant fiber or a mixture of aramid fiber and carbon fiber, etc., as the aramid fiber is paraphenylene terephthalamide fiber or metaphenylene isophthalamide fiber, the former is preferable in terms of high temperature heat resistance, The latter can be used in relatively cold places.
The carbon-based fibers used in combination include flame-resistant fibers having relatively low heat resistance and the like, and the content and quality may be appropriately selected according to the place of use. On the other hand, for transporting an aluminum profile or the like in a low temperature state, the felt material 2 may be polyester fiber, or a cylindrical body such as wool may be used.

筒径に応じて縫いピッチと糸の張りを調整する。The reinforcing yarn 4 is a high-strength yarn that does not break even during compression work, and for example, Kevlar filament (trade name) or the like is used. Although the reinforcing thread 4 is generally sewn close to the long side of the belt-shaped felt material 2, when the vertical groove is cut on the inner circumferential surface of the cylindrical body after molding, the reinforcing thread 4 is not cut at the sewing position. It is necessary to set. Since the horizontal bending of the belt-shaped felt material 2 is generated when the sewing pitch of the reinforcing thread 4 is increased and the tension of the thread is strengthened, the sewing pitch and the thread tension are adjusted according to the desired cylindrical diameter.

いしても、単に補強糸４で縫い付けるだけでもよい。When the reinforcing thread 4 is sewn in a straight line, a film 3 of a low melting point resin or a non-woven fabric may be sewn to one side of the belt-shaped felt material 2 at the same time, as shown in FIG. The film 3 or the non-woven fabric needs to have a lower melting point than the fibers forming the felt material 2 and has a property of fusing the felt material 2 by heating. Therefore, the film 3 or the non-woven fabric is made of a low melting point resin such as polyethylene, polypropylene or EVA, and if the felt material is a fiber having high temperature heat resistance, polyester or the like can be used. This film 3 is obtained by laminating felt material, compressing it, and then heating it at a temperature higher than the melting point of the low-melting resin to melt and bond the low-melting resin, so that the obtained laminated body is formed into a cylindrical shape as it is. Keep shape. The film 3 may be sewn on one side of the belt-shaped felt material 2 as shown in the drawing, or simply sewn with the reinforcing thread 4.

を用いる。The felt material 2 horizontally bent by the reinforcing thread 4 is passed through a pair of conical rollers 5 and 5 (Fig. 2) to be flat and substantially evenly bent as shown in Fig. 3 to form a spiral felt material 6. Mold. The spiral felt material 6 is wound around an appropriate mandrel 8 to be laminated as illustrated in FIG. 4, and is strongly compressed by a press 12 from the side end of the felt laminated body 10. At the time of this winding, the inner side of the spiral felt material 6 is attached to the mandrel 8
The height of the felt laminated body 10 is drastically reduced by compressing the felt laminated body 10 as close as possible to the peripheral surface of the felt laminated body 10. Compressed laminate 14
Is impregnated and dried on the inner peripheral surface or the whole thereof while maintaining the compressed state by an appropriate fixing means. The resin used in the resin processing is selected according to the use of the cylindrical body. For example, for the conveying roller 16 made of aluminum as shown in FIG. 8, a heat-resistant epoxy type, acrylic type or inorganic type adhesive is used.

When 20 is formed, a felt roller having the pipe fixed to the compression laminate is obtained. Further, by impregnating and drying the resin on the inner peripheral surface or the whole of the roller, the roller can retain its shape.

うに、広範囲の用途がある高密度フェルトとなる。As a finishing process, the outer peripheral surface of the cylindrical body is surface-polished to obtain a high-density felt cylindrical body. The diameter of the felt cylindrical body of the present invention is determined according to the outer shape of the mandrel 8 and is generally about 35 m in diameter.
It is possible to manufacture up to a size of around m to 3 m. The method of the invention results in a high density felt with a wide range of applications, such as obtaining felt cylinders of 0.3 to 0.8 g / cm 3 from felt sheets of density about 0.05 g / cm 3. .

The side of the lateral side contracts in a wavy shape, and as shown by the alternate long and short dash line in FIG. The gently curved belt-shaped felt material 2 is curved almost evenly to form the spiral felt material 6, but by appropriately adjusting the sewing pitch of the reinforcing thread 4 and the tension of the thread, it is bent to a desired cylindrical body diameter. It becomes possible. Due to the presence of the reinforcing thread 4 sewn to one side of the spiral felt material 6, the felt laminated body 10 does not expand and deform in the center in the radial direction when strongly compressed by the press 12 Cylindrical compression compression body 1
It becomes 4. In this compression laminated body, the compression state is maintained as it is by an appropriate fixing means, or the film is melted and adhered by the low melting point resin film 3 which is sewn at the same time, or the inner peripheral surface or the whole is impregnated and dried with the resin. Even if the fixing means is removed, an accurate cylindrical shape can be maintained.
