Abstract
A device for cooling heated textile yarns derived from thermoplastic material includes a cylindrical cooling pipe (1) through which the yarn (2) is passed, the pipe (1) being filled with a cooling fluid and having a curved plate (3) inside it which covers the entire length of the pipe (1). A coaxial jacket (5) encloses the pipe and defines an annular cooling zone between the pipe and jacket. At the exit end of the pipe (1) is located a removable sealing plug which has an inlet and outlet for cooling fluid, and an air inlet. Cooling fluid and cooling air can pass into the pipe (1) via the sealing plug and circulate in the pipe and the annular zone so as to cause rapid cooling of the yarn.
