摘要：The thickness of successive sheets which are delivered by the feeders of agathering machine to a collating conveyor are monitored and a computer which isassociated with each feeder calculates the extent of deviation of the monitored thicknessfrom an acceptable value. Signals which are generated by the computers in the event ofexcessive deviation are used to arrest the motor of the gathering machine and/or toexpel the respective groups of sheets from the collating conveyor. Each computer iscaused to calculate a reference value on the basis of monitored thicknesses of nsuccessively delivered sheets whose thicknesses are within the acceptable range.
