Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tubular body continuous molding system for continuously molding tubular bodies having various sectional shapes from a braid composed of a braider.

[0002]

2. Description of the Related Art Conventionally, various braiders that compose a tubular braid have been known, and the braid composed by such a braider is once removed from the braider and then impregnated and cured with a resin. It is also known to produce rigid tubular bodies.

[0003]

In the conventional system in which a tubular braid is impregnated with a resin and cured to form a tubular body, the braider and the resin impregnation process are not connected as a continuous continuous molding system. Since the braid composed is once removed from the braider and sent to the next resin impregnation process, etc., productivity is poor, and since it is not a continuous continuous molding system, uniform quality is obtained. It was difficult to mold the tubular body. Further, the braid removed from the braider, because it is difficult to maintain the shape without a core member such as a mandrel, a step such as inserting the core member into the braid in the resin impregnation step is required, Productivity will be further deteriorated. Further, there is no known tubular continuous molding system for continuously molding a braid composed of a tubular shape into various sectional shapes.

The object of the present invention is to solve the problems of the conventional system for forming a tubular body by impregnating a braid with a resin, and to continuously produce tubular bodies having various cross-sectional shapes of uniform quality with excellent productivity. The object of the present invention is to provide a continuous molding system for tubular bodies.
