PURPOSE:To inhibit interference of molten glass flow introduced into nozzle adjacent to each other by arranging many nozzles protrusively to a material for a bushing plate with a fixed distance and providing a rod or a plate to above the space between each adjacent nozzles. CONSTITUTION:An aimed bushing plate 3 for prepg. glass fiber is provided by arranging many nozzles 2 protrusively to a material 1 for a bushing plate at a fixed distance and providing a rod 4 or a plate 5 to above the space between each adjacent nozzle 2 of the bushing plate 3. By this constitution, the flow of the molten glass into the nozzle 2 which is to form an almost same angle of voltex flow as the taper of the foot of the nozzle 2 causes no interference to each other since the flow is deflected by the rod 4 or the plate 5, resulting in the voltex flow of molten glass contg. no turbulent part. Accordingly, there is no fear of causing cutting or dispersion of denier in the glass fiber extruded from the nozzle 2 and drawn.
