Abstract
In accordance with the invention a thread carrying apparatus is proposed with a thread (2) lying in contact with or passing along the thread carrying apparatus with friction in the operating state. The thread carrying apparatus includes excitation means (3) for producing oscillations which reduce the frictional force between the thread (2) and the thread carrying apparatus. In this arrangement a resonator body (4) is provided with the thread (2) lying in contact with or passing along the resonator body with friction in the operating state. The resonator body (4) is designed in such a manner that the excitation means (3) produce resonant structural sound oscillations in the resonator body (4).
