Abstract
In a method of producing a tubular structure for a gas generator, a tubular body is positioned relative to a forming device having inner and outer tools, which are moved relative to an end portion of the tubular body until an inner circumferential surface of a neck of the end portion rests against a support surface of the inner tool to reduce a diameter of the end portion by a tool contour of the outer tool and thereby form a shoulder. The outer tool is held in position upon the end portion and the neck inner circumferential surface is calibrated by a calibrating surface on a calibrating member of the inner tool while an outer circumferential surface of the neck is supported by the outer tool, as the inner tool is removed from the end portion. The outer tool is then removed from the end portion of the tubular body.
