1. Electronic command-speed transmitter for the spindle drive of a ring spinning frame a) with a first sensing device (A), for generating an invariant, non-oscillating first movement signal describing the movement of a ring which is provided for guiding the yarn, b) with a second sensing device (B), for generating a second movement signal, which alternates as this ring reciprocates relative to a spindle carrier, and c) with a motion-superposition device for superposing these first and second movement signals, characterized d) in that the movement-superposition device possesses an adder (S8 ) which adds a command-value component, it being possible to pick off a command-speed signal (ss) at the output terminal of this adder (S8 ), e) in that this command-value component adder (S8 ) is functionally connected, on its input side, to the first sensing device (A), the connection being effected via a combined discriminator and NOT circuit (DI), f) this combined discriminator and NOT circuit (DI) generating, as a function of the first movement signal (a0 ), a first command-speed component (a1 ) which is invariant over the entire duration of the winding operation, does not oscillate, and exhibits a rise ramp (rn), an at least approximately constant segment (ka), and a descent ramp (ra), and g) in that the command-value component adder (S8 ) is, furthermore, functionally connected, on its input side, to the second sensing device (B), the connection being effected via a signal generator (TZ) which generates a trapezoidal signal, h) this signal generator (TZ) generating, as a function of the second movement signal, a trapezoidal signal representing a second command-speed component (b1 ) which exhibits a rise ramp (na), an at least approximately constant segment (ak), and a descent ramp (ar), alternating as the ring reciprocates. |
