Then, the bent metal thin plate 2 is inserted into the synthetic resin layer 3 to form the eaves gutter A, and the formed eave gutter A is passed through the inner surface of the mold of the sizing machine 10 having the cooling section 16. This relates to a method for manufacturing an eaves gutter, characterized in that the eaves gutter A is brought into close contact with the inner surface of the mold by suction through an air intake hole 17 opened on the inner surface of the mold of the sizing machine 10.

が変形するという欠点があつた。 In the conventional example, the thin metal sheet was not embossed and was fed in a flat state to a forming roll that curves the thin metal sheet into a U-shape. Because the elongation of the central part and the side edges are different, the edges on both sides stretch and become distorted, resulting in creases. When a thin metal plate with these creases is inserted into a synthetic resin layer, this distortion can be removed. There was a drawback that the eaves gutters were deformed when they appeared in the gutters.

供するにある。 The present invention has been made in view of the drawbacks of the conventional example, and an object of the present invention is to emboss the thin metal sheet pulled out from the uncoiler, so that both sides of the thin metal sheet during roll forming can be improved. To provide a method for manufacturing an eaves gutter in which the distortion of the edge is made uniform and no distortion appears in the eave gutter when insert molding is performed.

伸び、曲りを防止できるものである。 The present invention will be described in detail below with reference to illustrated embodiments. The wound thin metal plate 2 is continuously supplied from an uncoiler 1 to an embossing machine 5, and the thin metal plate 2 is embossed. The metal thin plate 2 has a thickness of about 0.2 mm, and is finely embossed in large numbers. Although FIG. 3 shows an example of embossing, the embossing pattern is not limited to this and can be arbitrarily selected. The embossed metal thin plate 2 is continuously fed to a forming roll 4. The forming roll 4 is provided with a large number of forming rolls 6, and gradually bends the metal thin plate 2 into a U-shape. In this case, while the thin metal sheet 2 is being bent from a flat state into a U-shape, the side edges 8 of the thin metal sheet 2 are longer than the center portion 7, but the embossing has already been performed before roll forming. Both edges 8
The embossing absorbs the elongation of the material, and no folds are formed on both side edges 8 even after roll forming. The thin metal plate 2 curved into a U-shape enters an insert mold 9 and is inserted into the synthetic resin layer 3. In this case, since no folds are formed on both side edges 8 of the thin metal plate 2, the eaves gutter A will not be deformed after inserting. The eaves gutter A pulled out from the insert mold 9 is the sizing machine 1
It is cooled and shaped at 0. After the sizing machine 10 is a take-up machine 11 consisting of a double conveyor.
are arranged, and the eaves gutter A is pulled out from the sizing machine 10. After passing through the take-off machine 11, the eaves gutter A is successively cut into predetermined lengths by a cutting machine 18. In the sizing machine 10, the upper mold 14 and the lower mold 15 are provided with a cooling part [cooling water hole] 16 for passing cooling water and an intake hole 17 that opens on the inner surface of the mold, and the intake hole 17 is connected to an exhaust pump ( (not shown) by communicating with
The eaves trough A passing between the upper mold 14 and the lower mold 15 is brought into close contact with the inner surface of the mold, so that shaping and cooling can be performed accurately and quickly. Since the thin metal plate 2 is embossed, its section modulus is improved and the eaves gutter A is strengthened. At the same time, the synthetic resin 3 enters into the embossment, preventing the synthetic resin layer 3 from elongating and strengthening the eave gutter A. It can prevent stretching and bending.

When the gutter is insert-molded, no distortion appears in the eaves gutter, and a good appearance without deformation can be obtained. Moreover, in the sizing machine,
Since the surface of the eaves gutter, where air is taken in through the intake hole and passes through the inner surface of the mold, is brought into close contact with the inner surface of the mold, the eaves gutter can be shaped accurately using a sizing machine, and the eaves gutter can be cooled quickly. .
