Abstract
One aspect of the invention is embodied in a machine for wrapping a heater wire around a cold cathode fluorescent lamp (CCFL). The machine includes means for holding a CCFL, means for guiding a heater wire, and means for moving the holding means in relation to the guiding means for the purpose of wrapping a heater wire around a CCFL that is held by the holding means. Another aspect of the invention is embodied in a CCFL wrapped with a heater wire. The process used to wrap the CCFL involves inserting the CCFL into a socket of an automated machine and feeding the heater wire into a heater wire guide of the automated machine. The socket is then moved in relation to the heater wire guide, by means of the automated machine, for the purpose of wrapping the heater wire around the CCFL.
