  • Patent number: 4699180
    Abstract: The vibration-damping mounting for the weaving machine comprises a number of bearing elements which rest on the weaving shed floor. The bearing elements are relatively rigid vertically and are resilient only horizontally. For good horizontal vibration damping, the spring rate of the bearing elements referred to the total mass of a weaving machine must not exceed the value ##EQU1## horizontally, while the spring rates of the bearing elements should be at least 10 times greater. With this kind of mounting, which is of more use particularly for weaving machine frames not having great torsional resistance, the environment near a weaving machine group experiences in practice surprisingly low amplitudes of vibration which are many times less than the amplitudes of vibration associated with a rigid machine mounting.
