Buffalo Bending Rolls bend structural sections and shapes into segments, circles or coils accurately and economically at high production rates. They are manufactured in five sizes with roll tonnages of 15, 30, 50, 100 and 155. The Models of 1/2, 2, 2 1/2 and 3 have mechanical drives whereby power is transmitted from the drive motor through a worm gear reducer and a frame-mounted pinion train into the rolls.
