摘要

PROBLEM TO BE SOLVED: To keep the split property and the catenary of the strand in a specified range from the beginning to the end of the winding of the cake. SOLUTION: The binder is applied to a glass filament 11 formed of molten glass in a bushing 10 by a binder applicator 15, and then, the glass filament is divided into sub strands 20 by a gathering shoe 16, and the sub strands are bundled in one strand by a reinforcement pad 12. The bundled strand is wound around a collet 17 with a cylindrical tube 18 fitted to its outer circumference while traversed by a traverse finger 19. The traverse finger is moved in the separating direction from the collet according to the increase in the winding diameter of the strand so that the distance between a working point P of the strand in the traverse finger and the winding position Q where the strand is wound around the collet is in a specified relationship.
