The invention relates to a method and to a tool (1, 48) for producing a T-stringer, in particular in air travel and space travel. The method is characterised in that two intermediate strips (3, 4) are superimposed, sections (5, 6) of said intermediate strips (3, 4) being associated with a stringer base (60) that is to be formed, are separated from each other by means of separation films (7, 8) and the sections (14, 15) of the intermediate strips (14, 15) associated with a stringer rod (61) are brought into direct contact, in particular in a material fit. In a further method step, the sections (5, 6) of the intermediate strips (3, 4) associated with the stringer rod (61) that is to be formed are clamped in a clamping device (1). In another method step, the sections (5, 6) that are associated with the stinger base (60) that is to be formed, are folded in the counter direction (28, 29) by means of an unfolding pin (25) and pressed counter to the corresponding pressure surfaces (23, 24) of the clamping device (1) by means of a pressing cylinder (37), such that the sections (5, 6) are aligned exactly. Subsequently, only the folded intermediate strips (3, 4) are hardened in order to form the T-stringer that is to be produced. The invention method has an advantage over known methods for producing T-stringers in that a smaller number of steps are required in order to produce the T-stringer, and said steps could easy be automated. |
