ABSTRACT:
A method and apparatus is disclosed for producing dried sized glass fibers wherein a drying device is used to produce current flow along sized fibers to thereby partially or fully dry the size on the fibers. The apparatus may include an applicator for applying a size to the fibers and a drying device which comprises a high voltage electrode connected to a high voltage source and at least one grounded electrode. Drying is performed by passing the sized fibers by the electrodes such that a current flows along the sized fibers from the high voltage electrode to the at least one grounded electrode. The grounded electrodes may comprise grounded gathering shoes.
