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).

Abstract: An apparatus for stepwise bending of sheet metal strips into trapeze-shaped pieces comprises a vice set on each side of a press punch and opposed lower-side pressure cylinder arranged to grip a central portion of the metal strip and deform it in a vertical direction as the end portions of the metal strip are retained in the vice sets. Each vice set comprises an upper-side pressure cylinder including an upper vice plate and an opposed lower-side die including a lower vice plate arranged upon closing movement to grip the end portion of the metal strip extending therebetween. Each of the vice plates is movable in a horizontal direction to accommodate the vertical deformation of the metal strip.
