A corresponding method produces a pressure container.
Claims15
A method for forming connections from a reinforcing fiber, or reinforcing fibers, between walls of a wall assembly for a pressure container, the method comprising:
- for forming a connection or a row of connections between a first wall and a second wall of the wall assembly, respectively repeating:
- gripping each reinforcing fiber by a tufting needle at a gripping point of the reinforcing fiber from which a first portion and a second portion of the reinforcing fiber project;
- penetrating the first wall with the tufting needle, then penetrating the second wall with the tufting needle such that the gripping point penetrates the first wall and the second wall, and the first portion and the second portion pass through the second wall and the first wall;
- forming a loop between the gripping point and the second wall;
- and
- incorporating a supporting element into the loop.
