Abstract

A method for soft winding around a bobbin a false twisted yarn, which is delivered from a false twisting zone wherein false twists imparted into a fed yarn and running back therealong are heat set and which is heat treated by a second heater, the false twisted yarn being fed by means of a yarn delivery means to the bobbin in a winding apparatus. The time period wherein the false twisted yarn travels from the yarn delivery means to the bobbin is adjusted at a special value so that a soft wound cheese having a uniform and low apparent density and good shape can be obtained.
