Abstract

A centrifugal spinning apparatus is disclosed which includes a spinner disc (6) having a top wall (6a), a bottom wall (6b) and a side wall (6c) connecting the top wall and the bottom wall to each other, a plurality of spinning nozzles being formed in the side wall. The spinner disc is rotated at a high speed to thereby spin a molten pitch, fed into the spinner disc, into pitch fibers through the spinning nozzles. Heating members (l2a), l2b) are provided to the spinner disc (6). The heating members are made of electrically conductive heat­ ing material.
