1. A wet glass fiber forming package processing system, the system comprising:
a glass fiber producing apparatus comprising a bushing for extruding glass fibers;
an aqueous sizing applicator for applying an aqueous sizing to the glass fibers extruded from the bushing to form sized glass fibers;
a strand forming device for forming a glass fiber strand from the sized glass fibers;
a winding device for forming a wet glass fiber forming package from the glass fiber strand;
a magnetic metal support for supporting the wet glass fiber forming package; and
a microwave drier configured to dry the wet glass fiber forming package on the support to form a dried glass fiber forming package by subjecting the wet glass fiber forming package to microwave radiation having a frequency in the range of about 750 MHz to about 1,050 MHz.
