Abstract: A novel spinning apparatus is provided with a tubular coagulating liquid flow control valve body made of an elastomeric material and whose inner diameter is changeable according to external pressure. The valve body has a simple structure and is easy to retrofit to a conventional spinning apparatus. When dope is extruded, a mass of dope with gelled skin can pass easily and quickly through the opened valve body so that the spinning workability at the start of spinning is high. Further, since the coagulating liquid flows smoothly, the spinning speed can be increased without damaging the filaments.
