The invention relates to a device for the production of an angle for connecting a fuselage cell skin to an annular former and/or a stringer inside a fuselage cell structure of an aircraft, the angle taking place by the one-step deformation of an initially planar blank along at least three fold lines in a uniaxial compression molding device. A mounting frame with hinges is arranged in the compression molding device, the blank to be deformed being accommodated along the edges preferably by means of a plurality of peripherally arranged springs. A deformation of the blank into an auto-stabilized angle is possible in one step while simultaneously ensuring interlaminar slide. Due to the constructively conditioned auto-stabilization of the angle, additional components which increase the weight and the assembly effort (so-called “stabilos”) in the connection region between fuselage cell skin, stringers and annular formers inside a fuselage structure of an aircraft are unnecessary.
