ABSTRACT:
A multipass wiredrawing machine, particularly for drawing metal wires, comprising a plurality of traction drums for the wire that exits from a corresponding die, the drums being arranged mutually in succession in order to wind the wire that exits from the die and guide it on to the next die. Each traction drum is fixed with respect to the corresponding die and can move towards or away from the next die; the movement of the traction drum and of the corresponding die allows constant adjustment of the tension of the wire between the die and the drum and between the drum and the next die.
