Twin Clamp and Method for Simultaneously Clamping Two Elongate Profile Segments

A method for simultaneously clamping two elongate profile segments (71, 72) using a twin clamp (1) comprising two receptacles (61, 62), each of which has two movable clamping jaws (611, 612, 621, 622) and by means of each of which an elongate profile segment (71, 72) having a circular cross-section can be clamped in the contact section, each elongate profile segment having a centre axis (D71, D72) and an outside diameter, wherein two clamping jaws (611, 612, 621, 622) of different receptacles (61, 62) are coupled to one another via a respective differential gearing (41, 42) and two clamping jaws (611, 612, 621, 622) of the same receptacle (61, 62) are coupled to one another via a synchronous gearing (51, 52) and the position of the centre axes (D71, D72) of the clamped elongate profile segments (71, 72) is independent of the size of the outside diameters of the elongate profile segments (71, 72), comprising the steps of:

• securely clamping the two elongate profile segments (71, 72);
• and
• positioning independently the centre axes (D71, D72) of the clamped elongate profile segments (71, 72) regardless of the size of the outside diameters of the elongate profile segments (71, 72).
