Disclosed is a yarn tensioning system for keeping at least one yarn, which is taken from a yarn storage system to a yarn take-off system of a weaving machine, under tension. The system includes a brake roller around which the yarn is at least partially wound, and a motor for supplying a torque to the brake roller, the motor being actuable in generator operation to keep the yarn under tension between the brake roller and the yarn take-off system. Also disclosed is a weaving machine including such a yarn tensioning system, as well as a method for keeping at least one yarn under tension, the at least one yarn being taken from a yarn storage system to a yarn take-off system.
