The outer dies can be placed in three positions on either side of the tube roller as shown below. The position on the outside (position 1) requires the least amount of force to bend material while the innermost position (position 3) requires the most force to bend material. The placement of the dies also affects the bend radius. | The outer dies can be placed in three positions on either side of the tube roller as shown below.
