Abstract
A system for controlling sheet feed in a sheet-processing machine having a feed table with front stops thereon includes a scanning device in the vicinity of the front stops for detecting an arrival of a sheet thereat. An angle sensor is attached to a shaft of the sheet-processing machine. A computing/control device has a device for assigning scanning signals from the scanning means to respective angular positions .phi.actual with stored setpoint values .phi.setpoint, for computing positioning data for correcting a subsequent arrival of a sheet, if there is a deviation .DELTA..phi. between angular positions .phi.actual and the stored setpoint values .phi.setpoint, and for transmitting the positioning data to an actuating device.
