b to extrude the second partial elongated material 11b under a forming temperature T 2 lower than T 1 to obtain the first partial elongated material 11b.
The composite extruded material 31 is integrally formed so as to engage with a. The second resin 27b that is heated and softened when the second partial elongated material 11b is molded is formed on the lubricating surface 12a of the first partial elongated material 11a in the second extrusion molding die 22b.

い。Thereafter, the composite extruded material 31 is added to the second cooling tank 23.
It is cooled by b and hardened, and is taken up by the take-up machine 25, and the cutting machine 2
At 6, the composite long material 11 is manufactured by cutting it into a predetermined size.
The first cooling tank 23a is preferably air-cooled without using cooling water in consideration of forming the lubricant layer 15 later, but the second cooling tank 23b may be water-cooled, which allows efficient cooling. If the cross-sectional shape of the composite extruded material 31 is changed by a predetermined amount or a predetermined shape at a predetermined position along the longitudinal direction, the cutting may be performed by detecting the take-up amount and depending on the detected amount. it can. At this time, since the core materials 14a and 14b having a small elongation are embedded and integrated, the elongation is suppressed and the take-up amount can be accurately detected. In the above description, an example in which two extruders are used in one production line has been described, but instead of this, the first partial elongated material 11a is previously formed in a separate step, and this is formed into a drum or the like. It may be wound in a long length and continuously introduced into the second extrusion mold 22b while being unwound during use.

As shown in FIG. 2 , the vehicle body or the window plate which is bent from the state before bending indicated by the chain double-dashed line with the radius of curvature R of the inner peripheral portion and the radius of curvature R 2 of the outer peripheral portion in the bent portion 10 over the area of the angle θ The bending work piece 32 is obtained by the attachment to the. In this case, the partial elongated members 11a and 11b are bent with the engaging concave portions 13a and the engaging convex portions 13b being engaged, and the radius of curvature of the boundary line is smaller than R 2 but R
It becomes a larger R 1 . At this time, in the composite long material 11 as a whole, the partial long material 11a side is the compression region, and the partial long material 1
Although the side 1b becomes a tensile region and tries to extend, the core material 14b is integrally embedded inside the partial elongated material 11b to substantially prevent the elongation in the longitudinal direction. Scale members 11a, 11b are lubricated surfaces 12a, 12b
Since it is slidable in the longitudinal direction, the partial long member 11b located outside the bending center moves relatively to the other partial long members 11a. As a result, the tensile stress that is about to occur in the partial elongated material 11b located on the tensile region side is relaxed.

同じ効果が得られる。When bending without applying a tensile force during bending, as shown in FIG. 1 (a), the partial elongated members 11a and 11b have their inner sides bent with the neutral lines n 1 and n 2 as boundaries. The compression regions x 1 and x 2 and the outside of bending are the tension regions y 1 and y 2 , but none of them reach the size of the conventional region. Although a compressive stress is generated on the inner side of the bending and a tensile stress is generated on the outer side of the bending on any of the partial long members, by configuring the composite long member 11 with a plurality of partial long members 11a and 11b, each partial long member 11a can be formed. , 11b has a smaller width, whereby the stress generated on the inner side of the bend and the stress on the outer side of the bend are smaller than in the conventional case, and the occurrence of waviness and deformation is prevented. That is, the same effect as that obtained by bending the partial long members 11a and 11b separately and combining them can be obtained.
