ABSTRACT:
An apparatus includes a fiber tuft feeder with discharge rollers for delivering a fiber tuft mass; a drive motor connected to the discharge rollers; a feeding device arranged for advancing fiber material obtained from the tuft feeder; and a textile processing machine having an input arranged to receive fiber material from the feeding device. An opening roller forms part of the tuft feeder and is arranged downstream of the discharge rollers for receiving fiber material from the discharge rollers and to advance fiber tufts. Devices produce a loose fiber tuft mass from the fiber tufts delivered by the opening roller, form a thin fiber lap from the loose mass and advance the fiber lap to the feeding device. A sensor is situated upstream of the textile processing machine for detecting fluctuations in quantity characteristics of the advancing fiber lap, and a transducer is connected to the sensor for generating electric signals representing the fluctuations. A regulator is connected to the transducer and the drive motor for regulating the rpm thereof as a function of the electric signals.
