ABSTRACT:
A roll forming apparatus incorporates tension rolls which feed a material along a longitudinal direction thereof. The tension rolls are arranged at predetermined intervals and are driven. Also, forming rolls which form the fed material are arranged alternatingly on both sides in the width direction of the material between adjacent tension rolls. The roll forming apparatus described above prevents scratches on the material from forming as a result of the material sliding on the forming rolls.
