  • Drive system for a spindle frame
    Patent number: 4051656
    Abstract: The drive system is used for spinning, twisting or false-twisting machines. The spindles are driven by a tangential drive belt which is tensioned between a drive roll and a tensioning roll. The tensioning roll is mounted by a lever to pivot about a fixed axis. In addition, a rotatable axle is mounted about the fixed axis in order to drive additional working elements of the machine. The tangential belt is maintained under constant tension by a biasing means which biases the lever about the fixed axis.
