Abstract
A combination of a disc-type yarn tensioner is proposed, comprising a pneumatic cleaning device, which is fixedly assigned thereto. The disc-type yarn tensioner comprises an axle on which two brake plates are rotatably mounted by means of one rotary bearing each. It further comprises a pressure mechanism for applying axial pressure forces to the brake plates, which pressure forces press the brake plates against each other. The pneumatic cleaning device comprises at least one nozzle whose flow axis is directed from the outside substantially towards one of the rotary bearings. The compressed air flow exiting from the nozzle cleans the disc-type yarn tensioner. It is thus ensured that the rotary bearings of the brake plates accumulate less dirt and the rotary movement of the brake plates is braked with the intended braking force.
