1. A method of monitoring the performance of a controlled fiberization device for dispensing a continuous fiber of liquid coating material distributed through a space between the dispensing device and a substrate in a continuous helical pattern which changes position with time by a rotating motion in the space, said method comprising the steps of:

  • sensing the rotating motion of the pattern of the material in the space between the dispensing device and the substrate; and

    generating in response to the sensed motion a signal representative of characteristics of the motion of the pattern in the space.
