In addition, the above-mentioned (a) to (d) process is shown in Fig. 1, and the T-shaped mandrel is performed by various steps including the stopping sequence of the horizontal moving frame bl and the fan-shaped moving member b17. It is a kappa which can be formed on a barrel (m), and is not limited to the above-mentioned composition process at all.

In the above step (d), one end 1 of the mandrel m is dismantled from the mandrel mounting plate b34 'to rotate the mandrel m 180 degrees, and the other end 2 of the mandrel m ) Is attached to the mandrel mounting plate b34 'according to the means for attaching the mandrel m to the mandrel mounting plate b34' described using Figs. 19 and 20.

In the above-described embodiment, the case where the composition is formed on the T-shaped mandrel nl has been described. The composition is not limited to the T-shaped mandrel m, but the composition can be formed on the mandrel m of various shapes.

In the case of using the rod-shaped mandrel m, a plurality of braider bodies Bb may be arranged to form multiple braids on the rod-shaped mandrel m.

The effect shown by the Example of this invention mentioned below is listed.

Since the composition point on the mandrel is at the position where the axis of the bobbin placed on the bobbin carrier intersects the axis of the mandrel on which the composition is being applied, the thread strand rewound from the bobbin does not bend, thus smooth rewinding of the thread strand. At the same time, proper braid composition can be achieved to avoid excessive tension on the thread strands.

Since the composition point on the mandrel is at the position where the axis of the bobbin placed on the bobbin carrier intersects the axis of the mandrel on which the composition is being made, the size of the brader can be reduced, which improves the operability of the brader and at the same time the device of the radar. The area is reduced.

Since the amount of thread wound on the bobbin can be increased, the number of bobbin exchanges can be reduced, thereby improving the productivity of the brader.

Since the bobbin carrier is configured to run by the friction roller and the sliding friction roller, it is possible to prevent the occurrence of noise due to the tooth backlash of the gear.

By arranging the stabilizer position guide member, the fluctuation of the thread strand swinging in accordance with the transverse movement of the bobbin carrier running zigzag along the track provided in the upper plate can be regulated, and the composition point due to the movement of the mandrel Since the fluctuation of can be suppressed, a stable composition is realized without the yarns to be formed being entangled with each other in an irregular state near the composition point, whereby the shape of the formed braid can be made uniform and stable.

In addition, since the composition position stabilization guide member is disposed, when the mandrel is moved after the composition is finished, a plurality of thread strands connected to the braid formed by the second composition position stabilization guide member can be connected. It is possible to effectively cut the thread strands.

The mandrel can be easily and quickly attached to the mandrel mounting plate, thereby improving the productivity of the blader.

Cylindrical bobbin covers or elastic plates are installed so that when the bobbin carrier is inclined or upside down, the thread strands wound around the bobbin are drawn out or hang down and intertwined with the thread strands wound around the adjacent bobbins or The problem of being entangled with other members can be prevented.

Since bobbins mounted on the bobbin carrier and bobbins with heavy or reinforcing thread strands are wound around, it is not necessary to distinguish between bobbins with heavy or reinforcing thread strands and bobbins mounted on the bobbin carrier.

Since the cutting device is provided with a disc cutter for cutting the finished strand of the braid or the strand following the braid, it is possible to reliably cut the thread strand leading to the braid or the braid and to shorten the cutting time. In addition, since the tension applied to the thread strand at the time of cutting the braid or the thread strand following the braid can be reduced, it is possible to prevent the shape of the braid from collapsing.

Since this invention is comprised as mentioned above, it shows an effect as described below.

Since the mandrel is placed inside the track provided through the curved upper plate, the thread rewinding from the bobbin does not bend, so that the thread rewinds smoothly and excessive tension is applied to the thread. Since there is no work, an appropriate composition of the braid can be achieved.

In addition, since the mandrel is disposed inside the track provided through the curved upper plate, the bladder is downsized, the operability of the bladder is improved, and the installation area of the bladder is reduced.
