Yarn tensioning system and method for keeping a yarn which is taken from a yarn storage system to a yarn take-off system of a weaving machine under tension

A yarn tensioning system for keeping at least one yarn under tension, the system comprising:

• a brake roller rotatably arranged in a yarn tensioning system,
• at least one yarn that is at least partially wound around the brake roller,
• a motor supplying torque to the brake roller, wherein the motor is actuable in generator operation to keep the at least one yarn under tension, wherein the motor is actuable in motor operation to recover the at least one yarn between the brake roller and the yarn take-off system in a second direction that is opposite to the first direction, and
• a funnel-shaped guide for guiding the at least one yarn to the brake roller, wherein the funnel-shaped guide comprises a top open end and a bottom open end, wherein the top open end is wider than the bottom open end,
• wherein the at least one yarn is taken, under tension, from a yarn storage system in a first direction to a yarn take-off system of a weaving machine.
