つて左方向に、カムホロワ72を芯として傾動する。As already explained in the description of the entire tying machine, one of the winding bobbins 210 mounted on the turret disk 1 is provided with a continuous groove 2 of the winding bobbin by the tying wire supply device 4.
After the binding wire 400 is supplied in a shape over 34 hours,
As the turret disc 1 rotates, the wire rod 50 is fed into the wire hanging device 5, where the wire rod 50 is wound around the cylindrical portion 215 of the winding bobbin in a predetermined length, and its ends are also cut and bent. The cut end is also gradually wound onto the winding bobbin, and the winding bobbin is stopped at a predetermined position. Next, due to the rotation of the presser cam plate 31 attached to the intermediate shaft 17 of the central drive shaft 310 of the turret disk 1, the cam follower 72 rotatably attached to the lever 71 comes into contact with the peak 57 of the presser cam plate 31. When the lever 71 enters the trough 58, the lever 71 tilts to the left as viewed in FIG. 3, with the cam follower 72 as the center.

る。Therefore, the bracket 6 is fixed to the boss 64 at the other end of the shaft 63, which is integrated with the boss 70 fixed to the lever 71.
5 is tilted in a direction approaching the outer periphery of the winding 502 formed on the winding bobbin (see FIG. 3). Therefore, the pair of rollers 69a, 69b of the roller bracket 66 supported by the bracket 65 comes into contact with the outer circumferential surface of the winding 502, and presses the outer circumferential surface at two points while maintaining an appropriate distance.
Normally, the elastic wire wound around the bobbin moves backwards and swells in an attempt to return to its original state, and thus tends to unravel from the bobbin. By pressing it in place, you can prevent it from unraveling from the bobbin. Next, when the turret disc 1 rotates by a predetermined angle, the pair of rollers 6
The winding bobbin 210 moves to the next binding device 7 while the outer circumferential surface of the winding material is still being pressed by the coils 9a and 69b.

に貢献することが大きい。When the cylinder 32 connected to the horizontal lever 34 attached to the boss 20 provided at the end of the intermediate shaft 17 is operated, the reciprocating movement of the piston rod 36 is transmitted to the presser cam via the horizontal lever 3 boss 20 and the intermediate shaft 17. The information is transmitted to the plate 31 and the presser cam plate 3
1 performs a rotational movement, and the positions of the peaks 57 and troughs 58 of this cam plate are shifted. The device of the present invention presses the outer circumferential surface of the wound wire with two rollers to prevent the elastic wire from unraveling. By continuing to press the outer circumferential surface of the wound wire until the binding is completed in step), it is possible not only to prevent the wire from unraveling through the two steps.
It has features such as being able to completely prevent unraveling with an extremely simple mechanism, and will greatly contribute to technological progress in related industries.
