４ａ。The manufacturing method of the molding 3 described above is as follows: First, metal strips are roll-formed into different cross-sectional shapes to form elongated profile members 4a and 4b with a number of 'Pfl', which are introduced into an extrusion mold and made of synthetic resin The B auxiliary material 5.6 is integrally formed by extrusion molding, and the molding material 11 is obtained by cutting. A plurality of irregularly shaped members 4a constituting the molding material 11
, 4b are lined up in the width direction as shown in FIG. 2, and the respective profiles 4a are clamped by clamps 17, 18 as shown in FIG.

は内周側における縮み率を（−）で表示する値である。With the longitudinal ends of the molding material 11 clamped independently and movably in the longitudinal direction of the molding material 11, the molding material 11 is pressed against the bending die 19 and moved in the Y direction while applying tension in the X direction. After bending so that the elongation rate of the inner peripheral edge 13a at the bending part 10 of the deformed material 4a located on the outside is smaller than the elongation rate of the outer peripheral edge 12a of the deformed material 4b located on the inside of the bending, each deformed material 4a is bent.
, 4b are secured with flanges 15, 16. Here, the elongation rate is a value indicating the shrinkage rate on the inner circumferential side as (-).

有するモールディング３を得ることができる。Here, since the longitudinal ends of each of the deformed members 4a and 4b are clamped independently, when the deformed members 4a and 4b are pressed against the first bending mold 19 and bent, the deformed member 4a located on the outside of the first bend is drawn out in the longitudinal direction. By doing so, the molding 3 having the above elongation rate can be obtained.

合、異形材を作る型の数を削減することができる。The profiled members 4a and 4b may be made separately as in the above embodiment, but as shown in FIG. 4(A), the cushioning material 5.
After integrally forming 6, the bent portion 22 is cut, or
Alternatively, as shown in FIG. 4(B), the roll-formed product 23
By cutting a part 24 and rotating it in the two directions of the arrows, it is possible to form the parts side by side, and in this case, it is possible to reduce the number of molds used to make the irregularly shaped parts.

象は生じない。The elongation rate of the outer peripheral edge 12 during bending is greater than the elongation rate of the inner peripheral edge I3, and the difference increases in proportion to the width of the long material to be bent. Therefore, when the molding material 11 with the width W is bent as shown in FIG. 8, the difference in elongation becomes large, but as shown in FIG.
1 width W is divided into width V and 172 irregular shaped members 4a.
, 4b, when the deformed material 4a is bent while being moved in the longitudinal direction, the elongation rate of the inner circumferential edge 13a at the bent portion 10 of the deformed material 4a located on the outside of one bend becomes the deformed material 4b located on the inside of the bend. Even when the overall bending radius R is small, the difference in the elongation rate between the outer circumferential edge and the inner circumferential edge of each deformed member 4a, 4b becomes smaller. Therefore, the bending radius R can be made small, and even in this case, breakage of the outer peripheral edge 12.12a and thinning phenomenon do not occur.

Any value of 0 may be used.

調等の変化のないモールディングが得られる。In the molding of the present invention, the elongation rate of the inner periphery of the bent part of the profiled material that is located on the outside of the bend is as high as 1 on the inside of the bend.
Since the elongation rate is smaller than the elongation rate of the outer circumferential edge of each deformed member, the difference in the elongation rate between the outer circumferential edge and the inner circumferential edge at the bending part of each deformed member can be reduced, and as a result, the overall width can be reduced. Even if the bending radius is large, the bending radius can be made small, and since the outer periphery is not stretched excessively, a molding without breakage or change in gloss, color tone, etc. can be obtained.
また本発明の製造方法によれば、容易に曲げ加工を行い
