Abstract
Abstract A WIRE PASSING UPWARDLY AFTER HAVING PASSED THROUGH A MOLTEN METAL COATING BATH IS CONTACTED WITH A MOVING STREAM OF WATER JETTING UPWARDLY THROUGH THE ATMOSPHERE AT AN ANGLE. THE STREAM OF WATER AND THE MOVING WIRE MEET JUST AT THE APEX OF THE STREAM WHERE THE ENERGY OF MOVEMENT OF THE WATER IS LEAST. THE COOLING STREAM OF WATER THUS CAUSES A MINIMUM DISTURBANCE OF THE STILL MOLTEN COATING ON THE WIRE.
