In addition, the rear guide roller 340 installed at the rear of the rotating frame 320 supports both side portions of the raw material 1 to be discharged to guide the discharge direction. Two rear guide rollers 340 are extended side by side, the outer circumferential surface of the rear guide roller 340 is formed so that the outer diameter is gradually smaller toward the center from both ends to become a curved surface.

This is because the raw material 1 is discharged in a state of being bent at a predetermined angle by the rotation of the rotating frame 320. Since the angle at which the raw material 1 is bent depends on the angle of rotation of the rotating frame 320, Both side positions are not always the same. Therefore, the rear guide roller 340 is formed such that the curvature of the outer circumferential surface corresponds to the curvature of the circle of the diameter corresponding to the width of the raw material 1, so that both sides are rear guide rollers even when the raw material 1 is discharged at any angle. It is desirable to be supported and guided by 340.

Although two guide roller units 300 are illustrated in this embodiment, only one guide roller unit 300 may be installed, or three or more guide roller units 300 may be installed as illustrated in FIG. 7. When the plurality of guide roller units 300 are installed, the bending angle may be sequentially increased from the front guide roller unit 300 closer to the supply roller unit 200 to the rear guide roller unit 300.

Referring to the process of manufacturing a spiral file through the apparatus 10 for manufacturing a polymorphic spiral file according to the present invention described above.

First, the raw material 1 on the strip for processing the spiral pile is introduced into the feed roller unit 200. The raw material 1 on the strip is supplied at a constant speed backward through the feed guide portion 210 and the upper feed roll 212 and the lower feed roll 213 of the feed roller unit 200.

Raw material 1 on the strip passing through the feed roller unit 200 is installed to pass through the hollow portion 321 of the guide roller unit 300, in this case, both side guide rollers 330 of the guide roller unit 300 The both ends of the raw material 1 are gripped.

In this state, the rotating frame 320 is rotated at a desired angle, and when the raw material 1 is moved rearward from the supply roller unit 200 and the guide roller unit 300 by the guide roller unit 300 rotated. Since the raw material 1 on the strip is discharged backwards at a predetermined angle, the raw material 1 on the strip is processed into a spiral shape.

Here, the rotation angle of the raw material 1 can be adjusted by rotating the rotation frame 320 of the guide roller unit 300 through the rotation angle adjustment unit 350, the plurality of guide roller unit 300 in sequence In the case of arranging, the angle of bending in each guide roller unit 300 may be processed to be sequentially deformed so as to increase gradually from the front to the rear.
