Method and apparatus for producing uniform strands from a split fiber glass bushing.

摘要

A method of equalizing production on a split fiber glass forming bushing is described involving averaging the temperature measured across a bushing face plate, and controlling the power input to the bushing in response to that measured average. The two halves of the bushing are controlled by placing a variable resistor in the power supply lines to the bushing and adusting current input to the sides in response to variations in weight or yardage measured for the two strands produced by the split bushing.
