The above-mentioned drive mechanism 35 is constructed by connecting the first driving disk 18 to the tip of the first driving disk 17 via the connecting plate 15. Note that the disk 18 has an insertion hole 36 in its center for passing the wire.
is formed. That is, as the disc 18 rotates, the base end 12a of the pressing rod 12 swings about the pivot shaft 11 and comes into contact with the wire W or moves away from it.

Further, as shown in FIGS. 1, 2, and 6, the second pressing guide means 4 includes a second drive disk 27 having an insertion hole 37 for passing the wire W,

That is, the first pressing guide means 3 corrects the wire rod W so that it is almost at the center of the cutting part of the cutting device B, and does not suddenly perform high-precision centering of the wire rod W to be fed. , the wire rod W does not bend, and the wire rod W is
When being guided by the pressure guide means 4, the wire W is roughly corrected by the first pressure guide means 3.
Since the wire rod W is held by the wire rod W, the wire rod W smoothly passes through the second pressing guide means 4 without swinging, and is fed into the cutting device B while finishing centering is performed.

The extrusion onto the wire W by the first pressure guide means 3 is applied by bringing the base end portions 12a of the press rods 12 arranged at predetermined pitches along the circumferential direction into contact with the wire W, Rather than high-precision center alignment, rough corrections can be reliably performed.

The pressure on the wire W by the second pressure guide means 4 is applied by pressing the rollers 19 of the movable pieces 22 arranged at predetermined pitches along the circumferential direction, so that the wire W runs smoothly. Finishing center alignment can be performed reliably while being performed in a consistent manner.
