Clamping system for seven-fold cutting

A pipe processing machine with a clamp for seven longitudinal profiles (1, 2, 3, 4, 5, 6, 7) arranged next to one another and oriented in a longitudinal direction (L), said clamp having one clamping jaw (11) and another clamping jaw (12) which are movable towards one another and away from one another, with a one receiving area (13) in the one clamping jaw (11), the one receiving area has a bearing face (13c) at a bottom for two of the seven longitudinal profiles (2, 3), said bearing face being movable at least in some regions relative to the one clamping jaw (11) transversely to the longitudinal direction (L), and with another receiving area (14) provided in the other clamping jaw (12) for a bearing of four others of the seven longitudinal profiles (1, 4, 5, 6) and the one receiving area (13) and the other receiving area (14) are moveable towards one another and away from one another characterized in that the one receiving area (13) is formed in a prismatic shape as seen in cross section and has between lateral bearing faces (13a, 13b), a bottom bearing face (13c), which is moveable relative to the lateral bearing faces (13a, 13b).
