Abstract
The invention relates to a yarn-tensioning device for producing a specific thread pull on a thread () that is unwound from a winding point () of a creel () and is guided to a warping machine arrangement (). Said yarn-tensioning device comprises a rotating body () which is at least partially wound round by threads and an electric motor () which is connected to the rotation body. Said motor () is equipped with at least one brake transistor () for discharging excess energy produced when the generator of the motor is operated, said brake transistor being able to convert generator energy, arising when the generator is operated, into heat.
