A Stiffener manufacturing method and apparatus appropriate for manufacturing a stiffener such as a flat bar is disclosed. The stiffener manufacturing method is composed of a steel plate arrangement step, a strip-cutting step and a pattern cutting step, which are performed in a predetermined interval of time at a position. The stiffener manufacturing apparatus is composed of a matrix working table on which the steel plate is put, a guide rail which is installed in either side of the matrix working table, a stripping carriage which passes over the upper portion of the steel plate installed on the matrix working table, and in which a plurality of stripping torches for cutting the steel plate into a plurality of strips are installed in a predetermined distance spaced from each other, the stripping carriage being capable of linearly travelling along the guide rails, and a patterning carriage which passes over the upper portions of the strips installed on the matrix working table, and in which a patterning torch for cutting the strips into a predetermined pattern is installed, the patterning carriage being movably installed along the guide rail in a predetermined distance spaced from the stripping carriage. Using the stiffener manufacturing method and the apparatus thereof, an exact dimensioned stiffener can be efficiently mass-produced.
