いる。As shown in detail in FIGS. 8 (A) and 8 (B), this dividing device 10 has dividing teeth 9 with an interval corresponding to the interval between the continuous horizontal bar portions 3, 3 of the locking piece assembly 6. It is configured in a gear shape protruding at equal intervals, and the pitch circle of this cutting device 10.
10a is arranged so as to pass on the axis of the hollow needle 11, and the cutting device 10 is adapted to be intermittently driven and rotated at intervals between the horizontal rod portions 3, 3 whose cutting teeth 9 are continuous. . By the dividing device 10 which is driven intermittently, as shown in FIG. 8B, the thin wall portion 4 between the horizontal rod portions 3, 3 whose outer ends are supported by the guide walls 8b, 8b is divided from the inner side. Both of the divided horizontal piece 3 of the locking piece 5 can be clamped between the cutting teeth 9 and fed to the axis of the hollow needle 11 at the same time.
そして、この分断・移送の際には、第８図（Ａ）に示す

することができる。Then, at the time of this dividing / transferring, as shown in FIG. 8 (A), the horizontal bar portion 3 located on the axis of the hollow needle 11 after the dividing.
And a horizontal bar portion 3 located at the rear side and not yet divided, a separation distance Y wider than the horizontal bar portion distance X of the locking piece assembly 6 is formed. Despite the fact that the end portion of two continuous horizontal rod portions 3 is in contact with the end face of the piston rod 12 of the extrusion device at the same time, it is generated even though the portion 3 is a locking piece assembly 6 that is closely continuous. It is possible to prevent the cause of the failure that occurs.

ができる。Further, the intermittently driven dividing device 10 has the dividing teeth 9, 9
In the meantime, the horizontal bar portion 3 after being divided can be sandwiched and reliably fed to the axis of the hollow needle 11, and the hollow needle 11 waits on the axis line until the horizontal bar portion 3 is pushed out. The tip portion of the piston rod 12 can be guided back and forth between the dividing teeth 9 of the dividing device 10 and the bending of the piston rod 12 can be prevented.

Locking pieces are formed by connecting the horizontal bar portions to each other by the thin-walled portions at the portions where the horizontal bar portions are in close contact with each other, and the locking piece assembly is projected to the periphery at equal intervals. By intermittently rotating the tooth-shaped cutting device, the thin wall portion between the horizontal bars is divided to form a single locking piece in which the horizontal bar is located on the axis of the hollow needle, and the horizontal bar of this locking piece is hollow. Since it is pushed into the hollow needle by pushing it out on the axis of the needle, the horizontal bar portion that constitutes the locking piece itself without using the connecting rod and the connecting piece as in the past is used. By connecting laterally by the thin part of the parts that are in close contact with each other,
It is possible to form a locking piece assembly that is small in volume and has no waste. Moreover, this locking piece assembly can divide the thin portion between the horizontal bars to form a single locking piece in which the horizontal bar is located on the axis of the hollow needle. The lateral bar portion of the locking piece located on the line can be pushed into the hollow needle by extruding it on the axis of the hollow needle.

出装置により中空針中に押し込むことができる。Further, the locking piece driving device according to the present invention includes a head portion, a filament portion extending from the center of the head portion to one side,
A locking piece composed of a horizontal bar portion whose central portion is fixed to the extended end of the filament portion is connected to a thin wall portion where the horizontal bar portions are in close contact with each other to form a locking piece assembly, The locking piece assembly is divided into a single locking piece by a cutting device that divides the thin portion between the horizontal bars, and the horizontal bar of the divided locking piece is positioned on the axis of the hollow needle. Since the horizontal bar of the locking piece is pushed into the hollow needle by the pushing device located on the axis of the hollow needle, the locking piece itself can be used without the need for a connecting rod and connecting piece as in the conventional case. By using the lateral bar portions to be laterally connected by utilizing the thin portions of the portions that are in close contact with each other, it is possible to form a locking piece assembly that is small in volume and has no waste. Moreover, this locking piece assembly can simultaneously divide the thin wall portion between the horizontal bar portions and position the divided horizontal bar portion of the locking piece on the axis of the hollow needle by the dividing device. The horizontal bar portion of the locking piece located on the axis of the hollow needle can be pushed into the hollow needle by an extrusion device independent of the cutting device.
したがって、本発明によれば下記の効果を奏することが

きるから従来の係止片集合体におけるような連結片や連
結棒を省くことが可能となる。In order to divide the thin-walled part between the horizontal bars of the locking piece assembly by intermittent rotation of the gear-shaped cutting device in which the dividing teeth project at equal intervals, the cutting teeth are separated from each other during the cutting. Since it suffices to enter, the horizontal bar portions can be brought into close contact with each other, so that it is possible to omit the connecting piece and the connecting bar as in the conventional locking piece assembly.

断力が大きい。As in the past, the pushing rod laterally pushes out the locking rod with the piston rod of the pushing device, and at the same time, the connecting rod is divided by the pushing force (push-cut separation, JP-A-57-46729), or the piston of the pushing device. Compared with the case where the lateral rod portion of the locking piece is pushed out by the rod and the pushing force simultaneously causes the connecting rod to come into contact with the cutter to divide the connecting rod (JP-A-57-114433), However, since the cutting is performed by the operation of the cutting teeth by the rotational force of the gear-shaped cutting device, the cutting force is large.

まり合いなどの不都合を避けることができる。Therefore, not only when the side portions of the horizontal rod portion are partially connected to each other as shown in FIG. 1, but also when the side portions of the horizontal rod portion are connected to each other as shown in FIGS. 2 and 4. Even in the case of connecting from one end to the other end in the parallel direction along the length direction of the parts, the horizontal bar parts can be separated from each other. In addition, when the side portions of the horizontal rod portion are connected from one end to the other end in the parallel direction along the length direction of the horizontal rod portion, since the horizontal rod portions do not shift from each other, the side portions of the horizontal rod portion are not displaced. It is possible to avoid inconvenience such as entanglement of the locking pieces in the locking piece assembly as compared with the case where the locking pieces are partially connected to each other.

う問題が生じない。In the present invention, since the pushing out of the horizontal bar portion of the locking piece and the division between the horizontal bar portions are performed by separate devices, the pushing device portion has a large load because the pusher and the cutting are combined as in the conventional case. As a result, the problem of more failures than other parts does not occur.

法。1. A locking piece comprising a head portion, a filament portion extending from the center of the head portion to one side, and a lateral rod portion having a central portion fixed to an extended end of the filament portion, the locking piece The rods are connected to each other by the thin-walled portions to form a locking piece assembly, and the locking piece assembly is formed by intermittent rotation of a gear-shaped cutting device in which the dividing teeth project at equal intervals. The thin wall portion between the horizontal bars is divided to form a single locking piece with the horizontal bar positioned on the axis of the hollow needle, and the horizontal bar of this locking piece is pushed onto the axis of the hollow needle with a piston rod. A method for driving a locking piece, characterized in that it is pushed into a hollow needle by being ejected.
