A tube feeding device, particularly for use in a bending machine, comprises two units spaced from one another at a predetermined distance to form a tube magazine therebetween. A carriage with a recess to receive one individual tube is positioned at the bottom of the tube magazine. A chain conveyor is provided in the device adapted to receive individual tubes from the recess and transport the tubes toward the bending machine. The carriage is adapted to move towards and away from the chain conveyor to deliver the individual tube to the conveyor which is provided with a plurality of grippers adapted to carry the tubes and to advance them in a vertical direction.
