摘要: An apparatus is described for drawing synthetic yarn and rendering the yarn in condition for immediate crimping. The apparatus which is relatively compact, draws the yarn between a surface roughened draw pin and a heated roll. The yarn is heated to its drawing temperature by frictional contact with the draw pin surface. The apparatus produces an improved yarn in that a preheating stage is not required and the yarn is not permitted to shrink after drawing.
