Abstract (en)
[origin: EP0295601A2] A method is described for making a yarn, wherein a synthetic partially oriented multifilament yarn is delivered at a first speed to a pin, guided around the pin for between 270 DEG and 360 DEG , preferably for about 360 DEG , and then taken off at a second speed. This second speed is higher than the first speed. Thereafter the multifilament yarn is wound up. The pin used is an unheated pin having a diameter of less than 10 mm. Immediately after the multifilament yarn has been laid around the pin, the multifilament yarn is heated to a temperature between 100 DEG C and 250 DEG C for from 0.01 s to 10 s. <??>There is also described an apparatus for carrying out the method. This apparatus comprises a first delivery system for hauling off the multifilament yarn, preferably off a package, a pin wrapped by the yarn, a second delivery system for hauling the yarn off the pin, and a winder. The pin is constructed as an unheated pin having a diameter of less than 10 mm. A heater is situated between the pin and the second delivery system. <IMAGE>
