Title: Dual motor carriage drive

Abstract: A tube bending machine includes a carriage mounting a rotatable chuck for grasping and positioning a length of tube relative to the bending head of the machine. Motion of the carriage along the bed of the machine toward the bending head and rotation of the chuck relative to the carriage are powered by a pair of remotely mounted stationary motors each driving a chain. One chain is connected directly to the carriage and the other engages a sprocket rotatably mounted on the carriage and connected to rotate the chuck. The arrangement provides a differential drive in which the carriage can be driven by operation of both motors and the chuck can be driven by differential operation of the two motors. In addition the chuck can be rotated simultaneously with advance of the carriage.
