摘要:
A roll forming procedure with slitting to produce sections such as angle bars (15) and T-beams (21), which comprises a first set of roll forming passes applied to one single rolled product (10-110-210), the slitting of such product into two rolled products having the same cross-section and moving parallel to each other and a second set of roll forming passes applied to such two rolled products, in which procedure the passes of the first set are typical of the roll forming of cross-sections other than those of angle bars or T-beams.
