摘要：
A length measuring instrument includes a flexible measuring band which slides in a groove defined by a scale carrier body. The measuring band is fixed at one end to the carrier body. The second, free end of the measuring band is fastened in an oscillator which excites this free end into high frequency, low amplitude vibrations. These vibrations act virtually to eliminate harmful friction between the measuring band and the scale carrier body, and to reduce fouling of the measuring band markedly.
