PROBLEM TO BE SOLVED: To provide a molding device manufacturing moldings of various shapes and sizes with L-shaped cross sections with high dimensional accuracy. SOLUTION: This molding device 1 is provided with: a bending position holding part 2 having a mechanism for adjusting and holding the width direction end position of a long-sized material 9 to correspond to the bending position of a long side of L-shape; a bending part 3 having three pairs of bending rollers different in roller gradient from one another, sequentially from the small roller gradient and bending the material 9 in the bending position to perform L-shaped bending; a cutting part 4 having a mechanism for cutting the side to be the short side of the L-shaped material 9 into a predetermined dimension; a roller bending mechanism part 6 for performing roller bending of circular arc shape to an L-shaped long-sized material 19 obtained up to the cutting part 4; a control panel 8 having a function of setting the production number of seal fins for a steam turbine produced by the molding device 1 and controlling the cut length, an automatic operating function, and the like; and various kinds of auxiliary apparatuses required for various control and automatic operation.
