The invention relates to a twin clamp, 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 segment, each elongate profile segment having a centre axis (D71, D72) and an outside diameter, wherein pairs of clamping jaws (611, 612, 621, 622) of different receptacles (61, 62) are coupled to each other by means of a respective differential gearing (41, 42) and pairs of clamping jaws (611, 612, 621, 622) of the same receptacle (61, 62) are coupled to each other by means of a respective 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 magnitude of the outside diameters of the elongate profile segments (71, 72). |
