Abstract

Method of controlling or regulating tension in a thread being wound on a textile coil rolling on a winding roller of a thread-winding device, which includes varying the peripheral speed of the textile coil by varying the transmission ratio between the rotary speed of the winding roller and the rotary speed of the textile coil to an extent greater than the variation in the transmission ratio therebetween resulting from the increasing fullness of the winding on the coil.
