It configures with interfering.
As shown in Figures 2 and 4, engageable head forming section 50 has: being configured at the punch die (die) 51 of 42 top of mandrel, matches
It is placed in the engageable head forming hammer 52 of 42 lower section of mandrel and makes the drive shaft 58 of 52 rotation driving of engageable head forming hammer.In addition,
Punch die 51 and engageable head forming hammer 52 are configured to be respectively provided with the holding of the linking part J of coil chain tooth E between mandrel 42
The formingspace of space and engageable head H.
The bearing of the not shown scaffold of punch die 51, clamping is wound in mandrel 42 between the punch die 51 and mandrel 42
The part of the linking part J as coil chain tooth E in monofilament M.In addition, punch die 51 is configured to have for coil chain tooth E's
It is adequately rigid for 52 receiving pressing force of engageable head forming hammer when the forming of engageable head H.
As shown in figure 4, engageable head forming hammer 52 includes cylindric rotary shaft 53, axle center is parallel with left and right directions
And it is generally perpendicularly configured with mandrel 42；With disk-shaped pressing roller 54, concentrically it is wholely set with rotary shaft 53, by writing that surpasses all the others
It is around in the monofilament M of mandrel 42.In addition, engageable head forming hammer 52 is relatively configured across mandrel 42 and punch die 51.
As shown in figures 2 and 5, upper leg forming section 60 includes rotary shaft 61, generally perpendicularly matches relative to mandrel 42
It sets；It with disk-shaped rotary hammer 62, is wholely set concentric with itly in the front end of rotary shaft 61, pressing is wound in mandrel 42
Monofilament M and the upper leg La forming layer difference D in coil chain tooth E.In addition, the upper configuration of leg forming section 60 is on the right side of mandrel 42.
As shown in figure 5, the rotary shaft 61 of upper leg forming section 60 be inclined relative to horizontal and relative to mandrel 42 substantially
Orthogonally configure.In other words, the rotary shaft 61 of upper leg forming section 60 is flat relative to being divided by up and down direction and left and right directions
Face is parallel and configures across relative to up and down direction and left and right directions this two side.In addition, the upper leg of present embodiment shapes
Coil chain tooth of the portion 60 suitable for forming racket type.In addition, the coil chain tooth of racket type is that be formed with layer in upper leg La poor
The coil chain tooth of portion D.
As shown in Figures 5 and 6, the outer peripheral surface 63 of rotary hammer 62 includes the 1st bevelled perimeter faces 64, is formed in rotary shaft 61
Axial forward end side (side), and towards the necking down of axial forward end side；2nd bevelled perimeter faces 65 are formed in the axial direction of rotary shaft 61
Base end side (other side), and towards axial base end side necking down；With flat circumferential surface 66, configuration is inclined in the 1st bevelled perimeter faces 64 with the 2nd
Between oblique circumferential surface 65, it is formed parallel to the axial direction of rotary shaft 61.In addition it is also possible to be not provided with flat circumferential surface 66.
