    (54) Roll forming machine


    (57) A roll forming machine is disclosed having the upper and lower rollers at each stand mounted on cantilevered drive shafts. The upper and lower rollers are arranged in respective pairs so that the ends of each of the drive shafts of each pair extend towards each other. The drive shafts are attached to movable chassis which enable the axial distance between the opposing drive shaft ends to be adjustably varied thus varying the width of the rolled product.
