Disclosed herein is a forming apparatus for shaping a long plate member, which is continuously fed in a flat sectional configuration, into a U-shaped sectional configuration. The forming apparatus comprises an upper die and a lower die defining a forming part in surface which are in contact with each other for pressing the long plate member continuously fed into the forming part, and a drive mechanism for driving the upper die to continuously reciprocate in the vertical direction. The forming part defined between the upper die and the lower die includes an initial forming region which is located on an inlet for the long plate member and having a forming configuration corresponding to a flat sectional configuration, a final forming region which is located on an outlet for the long plate member and having a forming configuration corresponding to a U-shaped sectional configuration, and intermediate forming regions which are located between the inlet and the outlet. Sectional, configurations of the intermediate forming regions continuously change along a direction for feeding the long plate member, so that the forming configuration of the initial forming region approaches the forming configuration of the final forming region.
