Further, an inlet guide table 6 is provided in front of the molding machine base 4, and a length measuring roll 61 and a feed roll 62 are arranged vertically opposite to each other in the middle of the inlet guide table 6. ing. Then, the number of revolutions of the length measuring roll 61 whose circumference is defined in advance is measured by the rotary encoder 63 arranged at the end of the length measuring roll 61, and the amount of progress of the molding material A fed is measured. The measured progress amount is introduced into a control mechanism (not shown), a predetermined ratio corresponding to the progress amount is set, and the slide drive motor 4
2 and the speed reducer 43 are controlled. Therefore, the roll stand units 2 and 2 can be laterally moved and controlled according to the progress state (amount) of the forming material A.

A molding method using the molding machine having the above structure will be described below. A molding material A such as a metal plate material whose side edges are cut in a taper shape is applied to the molding machine of the first embodiment. First, when the inlet guide table 6 is exposed from the narrow end B of the forming material A and is advanced between the length measuring roll 61 and the feed roll 62, both rolls 6
1, 62 abut and support the forming material A and feed it to the inlet side 31 of the facing portion 3.

The narrow end B, which is the forward end of the forming material A, has its left and right side edges bent by the forming rollers 11 and 11 in the front row. The molding material A that is subsequently fed to the inlet side 31 of the facing portion 3 gradually becomes wider, but the molding rollers 11 and 11 in the front row gradually move laterally in accordance with the progress state of the molding material A as described above. In this case, since the movement is controlled outward, the left and right side edges of the forming material A are continuously bent. Then, the forming rollers 1 in the second and last rows
1 and 11 operate in the same manner and perform deeper bending. In this way, the taper-shaped exterior material D provided with the bent portions C formed by molding the left and right side edges of the molding material A is manufactured.

As described above, in the molding machine of the present invention, the left and right molding rollers 11, 11 simultaneously mold the left and right side edges of the molding material A, so that the productivity is excellent. Moreover, in the illustrated embodiment, the roll stand unit is arranged such that the width from the inlet side 31 to the outlet side 32 in the traveling direction of the forming material A is narrower, and the left and right forming rollers 11, 11 are moved laterally outward. Since the molding is performed under control, a tensile force acts on the intermediate portion of the molding material A. Therefore, even if a thin plate is applied as the molding material A, it is possible to perform the molding according to the dimensions without buckling of the intermediate portion or a molding error, which may impair the aesthetic appearance of the molding material A. Absent.

Further, in the first embodiment, the roll stand units 2 and 2 are arranged so as to be movable laterally with respect to the molding machine base 4 via the slide bases 5 and 5, so that the slide bases 5 and 5 can be moved. Roll stand unit 2, 2
Can be mounted at any angle. In this case, the facing portion 3 can be formed along the taper angle of the forming material A, and can be adapted to the forming of the forming material A having various taper angles. The roll stand units 2 and 2 may be directly arranged on the molding machine base 4 without providing the slide bases 5 and 5. In this case, for example, the fitting portion 51 and the bearing 52 provided on the lower surface of the slide base 5 may be attached to the lower surface of the roll stand unit 2.

Further, as shown in FIG. 5, the roll stand unit 2 may be constituted by the roll stands 1 ... Stored in the independent casing frame 22. Also,
In the illustrated embodiment, the forming roller 11 in which the left and right side edges are simply bent in a substantially vertical shape is shown, but the forming roller 11 is not particularly limited. That is, by selecting an appropriate shape as the forming roller 11, for example, an engageable shape such as fitting, overlapping, or engaging may be formed. In addition, the left and right side edges of the molding material A may have a curved shape instead of a straight shape.

That is, the facing distance between the forming rollers 11 and 11 in the front row in the state of the minimum limit was the minimum limit of the narrow end B of the forming material A that can be applied. However, in the fourth embodiment, since the forming rollers 11 of the left and right roll stand units 2 and 2 and the slit cutter 16 are not close to each other, it is possible to easily form the forming material A which cannot be conventionally applied. .

In the molding machine of the fifth embodiment shown in FIG. 11, the facing portion 3 of the molding rollers 11, 11 facing left and right is set so that the inlet side 31 in the traveling direction of the molding material A is narrower than the outlet side 32. Since it is the same as the first embodiment except that it is set as described above, the same reference numerals are given to the drawings and the description thereof is omitted.

In the fifth embodiment, the wide end G of the molding material A is made to face the entrance guide table 6 so that the molding material A becomes gradually narrower, but the molding rollers 11 and 11 are respectively formed as described above. As described above, the movement of the forming material A is gradually controlled in the lateral direction, in this case, inward, so that the left and right side edges of the forming material A are continuously bent. For such a molding machine, a thick molding material A that is less likely to buckle due to a compressive force acting inward may be applied.
