Is inserted through the through-hole 573b of the lever 573, and the bending rod is manually corrected. The pin 574 is provided to prevent the bending element 571 from rotating more than necessary in the counterclockwise direction of FIG.

  Next, the operation of the first embodiment configured as described above will be described. First, the notch 51a of the base 51 of the rope end processing apparatus 1 and the notch 32a of the pedestal 32 are matched as shown in FIG. 8, the fastening bolt 34b is loosened, and the fastening member 342 is removed. At this time, the opening portion of the guide frame 33 having a substantially U-shaped cross section and the opening portion of the rope guide frame 52 having a semicircular cross section face the same direction as the cutout portion 51a and the cutout portion 32a. The rope 2 can be inserted into the center of the rope guide frame 52. Next, after applying scissoring 7 to a predetermined portion near one end of the rope 2, the central portion of the rope guide frame 52 so that the one end 2 a of the rope 2 protrudes into the working portion 4 as shown in FIGS. 1 and 8. The rope 2 is fixed to the rope holding device 3 by inserting the rope 2 and tightening the fastening member 342 to the receiving seat 341 by the fastening bolt 34b.

  Next, the strand 2b of the one end portion 2a of the rope 2 protruding to the processing work portion 4 is unwound and stretched, and the hemp core 2d is cut from the root. And as shown in FIG. 9, the bending wrinkles of the strand 2b are corrected using the through-hole 573b of the lever 573, and the strand 2b is processed into a substantially linear shape. At this time, since the rope 2 is fixed by the rope holding device 3, it can be easily operated using both hands, and it is not necessary to use a tool such as pliers or pliers. Since the lever 573 is screwed to the bending element 571, it can be easily detached. The through hole 573b may be provided with a plurality of through holes having different diameters in one lever 573 so that it can be selectively used according to the diameter of the strand 2b, or a plurality of levers 573 having different diameters of the through holes 573b are prepared. You can keep it. The through hole 573b may be a long hole.

  Thereafter, the strands 2b whose bending wrinkles are corrected are set so as to be sequentially positioned above the groove 54a of the strand fixing portion 54, below the shaft pin 55, and inside the groove 571a of the bending element 571 as shown in FIG. The shaft pin 55 may be detachable or provided so as to be able to advance and retract in the axial direction of the shaft pin 55 in order to make it easier to set the strand 2b.
