    摘要: A method of evening a sliver produced by a carding machine in which a predetermined output rate and draft are set. The method includes the steps of determining the actual weight of a predetermined sliver length by weighing; determining the difference between the actual sliver weight and a desired sliver weight; as a function of the difference altering the draft corresponding to a predetermined sliver thickness; measuring momentary actual thicknesses of the running sliver at a card output for a determined time period or sliver length and generating mechanical signals representing the momentary actual sliver thicknesses; converting the mechanical signals to first electric signals; combining the first electric signals into a second electric signal constituting an average of the first electric signals and representing the actual sliver thickness of the measured sliver; storing the second electric signal; applying the second electric signal to a computer; applying to the computer a third electric signal representing the actual sliver weight; and determining, with the computer and from a function between the actual sliver weight and the actual sliver thickness, a desired sliver thickness corresponding to a desired sliver weight.

    摘要: An apparatus for evening a fiber lap fed to a carding machine. The latter has a licker-in, a feed table and a feed roller cooperating with one another in feeding the fiber lap to the licker-in; a drive motor connected to the feed roller; and an arrangement providing for a relative movement of the feed roller and the feed table towards or away from one another as a function of the thickness of the fiber material passing therebetween. There is further provided an excursion measuring device for generating signals representing the magnitude of the relative movement; and a control device connected to the excursion measuring device. The control device is connected to the drive motor for regulating the rpm of the feed roller as a function of the relative motion between feed roller and feed table. A delay device is connected between the excursion measuring device and the control device for delaying transmittal of signals from the excursion measuring device to the control device. An angular displacement measuring device for generating signals corresponding to an angular displacement of the feed roller is connected to the delay device for varying the extent of delay of transmittal of signals by the delay device as a function of the signals generated by the angular displacement measuring device.
