ABSTRACT:
An elongate heater for heating an advancing synthetic filament yarn with reduced friction. The yarn is advanced in contact with a generally flat contact surface of the elongate heater, with yarn guides being arranged along the heater in spaced apart relationship, and so as to guide the yarn in a zigzagged path with a predetermined amplitude over the contact surface. The yarn guides may be constructed as cylinders, which extend perpendicularly to the contact surface of the heater.
