It relates to the device.

[0002]

2. Description of the Related Art Conventionally, it is known that a composition composed by a braider is once removed from the braider and then impregnated and cured with a resin to form a tubular body. A tubular body manufacturing apparatus using a braider that impregnates and hardens a resin into a structured body to continuously form tubular bodies having various cross-sectional shapes on a mandrel is not known.

In the conventional apparatus for manufacturing a tubular body by impregnating and hardening a resin into a composition, the braider and the resin impregnation step are not connected as a continuous continuous manufacturing apparatus. The prepared composition,
Since it is configured to be sent to the resin impregnation process of the next process after being removed from the braider, productivity is poor, and it is difficult to manufacture a tubular body of uniform quality because it is not a continuous continuous manufacturing device. Met. Further, since the composition removed from the braider is difficult to maintain the shape without a core member such as a mandrel, a step of inserting the core member into the composition in a resin impregnation step or the like is required. Therefore, productivity will be further deteriorated. Further, there is known a tubular body manufacturing apparatus using a braider that impregnates and hardens a resin into a composition formed around a mandrel of a braider to continuously form tubular bodies having various cross-sectional shapes on the mandrel.

[0052]

Since the present invention is constructed as described above, it has the following effects. A resin-cured tubular body having an arbitrary cross-sectional shape can be continuously produced from a composition constituted by a braider, and a molded and cured tubular body can be produced by a consistent continuous molding system. Therefore, a tubular body of uniform quality is obtained. Since the tubular body is pulled by being sandwiched by the sub-mandrel and the pulling device, slipping does not occur between the pulling device and the tubular body, and the tubular body is reliably transferred without being deformed or damaged. Therefore, it is possible to eliminate the variation in the quality of the composition due to the unstable transfer of the tubular body.
