Abstract
Governor foot assembly for cyclically sensing the height of a feeder sheet pile of a sheet-fed printing press includes a governor foot mounted above the sheet pile so as to be variable in height and so as to be swingable out of the vicinity of the sheet pile and back into the vicinity thereof, a drive system for cyclically swinging the governor foot, after the height of the sheet pile has been sensed, out of a region above the sheet pile and, before the height of the sheet pile is sensed, again into the region above the sheet pile, and for cyclically lifting the governor foot after measuring the height of the sheet pile and again for lowering the governor foot before measuring the height of the sheet pile, respectively, a spring device having an adjustable spring tension, the spring device connecting the governor foot to the drive system, and a device provided on the governor foot for adjusting the spring tension of the spring device.
