Abstract
In a process and apparatus for manufacturing drawn and twisted multifilament synthetic yarn an extruded and partially drawn filamentary synthetic yarn is subjected to a supplementary, simultaneous, drawing and twisting operation using a double twist spindle rotated such that the tension in the yarn causes drawing. After the spinning and drawing, the yarn is subjected to heat treatment under controlled tension and is then wound up.
