ABSTRACT:
An apparatus for regulating the rpm of the feed roller of the tuft feeder and having an rpm measuring device connected to at least one card roller for generating a first signal representing an operational magnitude of the card roller; a signal generating device connected to an output of the rpm measuring device and arranged for generating a second signal as a function of the first signal; a pressure sensing device for sensing pressure in the feed chute and for generating a third signal representing the pressure; a regulator connected to an output of the pressure sensing device and arranged for generating a fourth signal as a function of the third signal; and an integrating device connected to an output of the signal generating device and an output of the regulator for receiving the second and fourth signals and emitting a fifth signal as a function of the second and fourth signals. The integrating device is connected to the output amplifier for applying the fifth signal thereto. The output amplifier is connected to the rpm-variable drive motor of the feed roller for the tuft feeder.
