昭60−158919号）。BACKGROUND ART For example, in manufacturing a wind molding M for an automobile as shown in FIG. 6, a metal strip material such as stainless steel is formed into a predetermined cross-sectional shape using a roll forming machine, After being bent and formed as a continuous molding material in advance, it is fed into a guide device that supports it so that it can slide along the axial direction, and the molding material that is linearly sent out from this guide device is swung on one axis. The molding material is fed into the axial bending device, where it is bent in a two-dimensional direction by the left and right bending rolls provided in the bending device, and the upper and lower bending rolls, which are spaced apart at the rear, are used to bend the molding material upward or downward. It has already been proposed to perform axial bending in a three-dimensional direction by swinging (for example, Japanese Patent Application Laid-Open No. 158919/1983).

作用する虞れがある。Problems to be Solved by the Invention In this type of continuous axial bending device for elongated members, after the elongated member is axially bent in a two-dimensional direction between a guide device and left and right bending rolls, the curvature remains unchanged. Since the long member is inserted through the upper and lower bending rolls located at the rear, the entire device is rocked on one axis in order to bend the long member to a small curvature and then to a large curvature. When the long member is moved and twisted back, the curvature of the elongated member inserted through the left and right bending rolls and the upper and lower bending rolls is different, so the axial line part that has already been bent as desired by the upper and lower bending rolls is bent. There is a possibility that it may act to weaken the

The purpose of the present invention is to provide a continuous axial bending device.
