Method and apparatus for controlling the sliver-thickness variation in a carding machine
 A method and apparatus for controlling the sliver thickness variation in a carding machine. The thickness variation of the sliver delivered from the carding machine is measured and an electrical signal corresponding to the thickness variation of the carded sliver is issued. A difference signal is created by comparing the above-mentioned electric signal, and a control pulse signal in accordance with the difference signal is intermittently created at predetermined time intervals, each of said time intervals being shorter than a time required for a length of the carded sliver which length corresponds to a long term variation of the carded slivers thickness. The supply amount of fiber tufts to the carding machine is intermittently adjusted for reducing the above-mentioned control signal toward zero by said control pulse signal at each of said time intervals.
