A multiple rotary drive system for a textile-working machine has first and second clutch-brake units. Each clutch-brake unit has a rotatable flywheel, a non-rotatable brake surface, and a rotatable shaft to be driven, whereby the rotatable shaft can be connected to the textile-working machine as a rotary drive of the system therefor. A clutch disc and a brake disc of each clutch-brake unit are connected to the shaft thereof for rotation therewith and are arranged for controllably engaging with, respectively, the flywheel for rotatably driving the shaft therefrom and the brake surface for braking rotation of the shaft therefrom. The flywheel of the first clutch-brake unit is rotationally driven, whereby the drive system can be driven by a continuously-rotating shaft of a continuously-operating electric motor. A belt extends about each flywheel for coordinate rotation of the flywheels when the one is rotatably driven by the electric motor. Then, when the clutch disc of either or both of the clutch-brake units is engaged with the flywheel thereof, the shaft thereof is rotatably driven in coordination with the drive of the one flywheel and the shaft of the other clutch-brake unit if its clutch disc is also engaged with its flywheel.
