Abstract
Abstract The spindles of the twisting machine are mounted on spindle rails which are directly or indirectly mounted on the machine frame by omnidirectally acting damping members such as rubber pads. In addition, a cover can be disposed about the spindle rails and spindle drives to damp noise. Finally, a damping element can be secured about the spindle rail to damp noise.

Total Claims: 15
Claim 1
Independent Claim
61 words
In combination with a twisting machine having a machine frame, a rigid frame including longitudinally extending stationary spindle rails to each side of said machine frame for supporting a plurality of spindles and a plurality of crossmembers rigidly connected to and across said spindle rails, and a plurality of omnidirectionally acting dampening members supporting said rigid frame on said machine frame.
Claim 2
Dependent Claim
61 words
In combination with a twisting machine having a machine frame, a rigid frame including longitudinally extending stationary spindle rails to each side of said machine frame for supporting a plurality of spindles and a plurality of crossmembers rigidly connected to and across said spindle rails, and a plurality of omnidirectionally acting dampening members supporting said rigid frame on said machine frame.
