Abstract: In a motor-driven rail vehicle, an arrangement is provided for sensing oscillations in the drive system occurring in a predetermined frequency range, and to reduce the torque of the motor if the oscillation amplitude sensed thereby exceeds a predetermined threshold value.

Abstract: The mechanically braked strip roller is for a winding appts. comprising a drum (8) with at least one gable (6) which rotates with it, and on the outside of which is a brake lining. The drum fits on a shaft (5), and on opposite sides of it are located non-rotatable plates movable axially and pressed by a spring (3) against the drum. The gable (6) is light and pliable, and with its brake lining runs right into the shaft.

Abstract: In apparatus having at least two roll pairs and/or stretch rolls each having a driving means with an amplifier for speed control, the speed control reference for each drive is developed by summing signals developed in adjacent control circuits such as to obtain a relationship in which, for example, for the second drive the signal is V0(1 + S1) (1 + S2) where V0 is a basic speed reference signal and S1 and S2 desired relative speed differences for first and second drives to thereby permit speed adjustments.
