Abstract: The present invention relates to a mould (42) for bending material parts, the mould (42) comprising opposite first and second longitudinally extending mould halves (1, 21) enclosing a longitudinal mould cavity (59). The first mould halve (1) comprises a plurality of parallel first plates (2), and the second mould halve (21) comprises a plurality of parallel second plates (22). The first and second plates (2, 22) extend in width direction of the mould (42), alternate in longitudinal direction of the mould (42) and comprise respectively a first and second end wall (5, 25). Consecutive first and second end walls (5, 25) form respectively first and second side walls (3, 23) on opposite sides of the mould cavity (59).
