Abstract (en)
The comber is operable to produce a sliver from a lap wound in the form of a lap roll and has a plurality of combing heads each having a lap feeder. The lap feeder has a motor that can be driven independently of a combing drive device. The lap feed control device is characterized in that it includes an arithmetic-logic unit and a control unit. When the comber is operated with the motor driven at a constant speed on a trial basis, variation of weight of the sliver relative to decrease of diameter of the lap roll is measured. The arithmetic-logic unit calculates a speed change pattern of the motor from the measurements to equalize the weight of the sliver or reduce the variation of the weight of the sliver. The control unit controls operation of the motor of the lap feeder in accordance with the speed change pattern.
