ABSTRACT:
An elongate member former is characterized by three-way powered forming movement and is composed of a main frame and a moveable die table mounted on the main frame and adapted to carry a die for being urged against the member to form the member into a predetermined shape. Carriage ways are carried on the main frame and first and second carriages mounted are on the carriage ways in spaced-apart relation on opposing sides of the die table. Member holders are carried by each of the first and second carriages for holding opposite ends of a member to be formed. Tensioners are carried by each of the first and second carriages for placing the member being formed under a predetermined tension. The first and second carriages rotate for applying a twisting forming movement to the member and the first and second carriages move the member holders vertically along a line perpendicular to the direction of tension application on the member for applying a nontwisting bend to the member.
