When the braid to be composed becomes thicker or the cross-sectional shape is irregular, etc. becomes more sophisticated, the braid will be
If you do not pull with a considerable pulling force in the winding direction,
The braid cannot be reliably wound on the bobbin at a constant speed. If the braid is not pulled out at a constant speed, the braids of the braid become rough or dense, a uniform mesh is not formed, and the quality of the braid is deteriorated.

Further, in order to reliably pull the braid in the winding direction at a constant speed, the driving device for driving the bobbin must be made strong, and therefore the winding device becomes large. There is.

Furthermore, when the braid is pulled while being nipped by a nip roller, there is a problem that the braid slips and rubs, damaging the composed braid.

An object of the present invention is to solve the problems of the above-mentioned conventional braid winding device and to provide a braid winding device capable of setting various winding conditions.

In order to achieve the above-mentioned object, the present invention comprises a pair of feed rollers, in which a braid composed of a braider is wound into a figure 8 shape and is positively drawn out. The braid pulled out by the pair of feed rollers is provided with a traverse mechanism that winds the braid while traversing the bobbin.
The braid composed around the mandrel is pulled out by the pair of feed rollers, and further, the composition speed of the braid of the braider and the winding speed of the braid on the winding bobbin are independently adjusted. It can be set separately.

The braid b, which is formed around the mandrel 4 and is pulled out from the mandrel 4 in a substantially horizontal direction, is guided by the guide roller 11 and is positively rotated and arranged below the guide roller 11. The direction of the feed rollers 13 and 14 is changed.

Alternatively, the two can be driven by a common motor as appropriate.

The braid b pulled out from the mandrel 4 is
When continuously processing with a resin impregnation device or the like, if the composition rate of the braid b of the braider B changes, the processing conditions will change. However, in the present invention, the braid b is once wound up on the bobbin 19 and then,
Since the braid b pulled out from the winding bobbin 19 is processed by a resin impregnating device or the like, the processing conditions of the braid b can be maintained constant and the processing conditions can be easily changed.

[0031]

Since the present invention is constructed as described above, the following effects can be obtained.

Since the braid is wound around the feed roller in a figure 8 shape and is positively pulled out, the braid can be reliably wound at a constant speed without slipping and wound on the winding bobbin. Get out. Therefore, it is possible to always form a braid having a constant mesh. In addition, since the braid is configured to be pulled out by the feed roller that is positively rotating, it is possible to prevent damage to the braid that occurs when the braid is pulled out while being sandwiched by the nip roller or the like.

Since the braid composed around the mandrel is pulled out by a pair of feed rollers,
It is possible to prevent variations in the speed at which the braid is extracted from the mandrel, and thus it is possible to form a braid with improved quality.

Since the braid braid composition speed and the braid braid winding speed can be set independently and separately, the braid composition can be performed under various conditions.
