Claims (1)

[Scope of Claim for Utility Model Registration] (1) A main frame, a center guide that can move forward and backward in the axial direction, and a long object that rotates around the center guide in a vertical plane while holding a long object between the center guides. at least three bender heads arranged parallel to each other in the longitudinal direction of the main frame spaced apart from each other, each having a bending roller for bending the length upward in a vertical plane; a drive shaft attached to the main frame; a slider that is configured to be able to hold a long object, is attached to the drive shaft, and moves on the drive shaft as the drive shaft rotates to convey the long object; A continuous bending device for long objects, comprising: a position detection means for detecting the position of the slider from the rotation speed of the drive shaft and adjusting the position of the slider in cooperation with a drive shaft drive motor. (2) The clamp means is equipped with a shielding block that can move forward and back to cover the top of a long object, and a pressing block that can move up and down that presses and clamps the long object on the side of the advanced shielding block, and the clamp means is a slider. 2. The continuous bending device for long objects according to claim 1, which is installed in a continuous bending device for long objects. (3) Three bender heads are installed on the main frame, with the bender heads on both sides movable and the central bender head immovable.
3. The continuous bending apparatus for long objects according to claim 2, wherein the clamping means having the above structure is also attached to the bender heads on both sides. (4) The position detecting means includes an encoder, and feeds back the rotation speed of the drive shaft detected by the encoder to a drive shaft driving motor, controls the rotation of the motor, and adjusts the position of the slider. A continuous bending device for long objects as described in any of the above.
