Abstract
In a sheet feeding device, the local feed of the sheet is measured in the vicinity of respective drive rollers by means of respective sensors for the purpose of aligning rectangular sheets of a preselected set. On the basis of signals from the light sensors, a control device determines an optimum pair of rollers for aligning the sheet. The control device compares the signals of the two associated sensors and adjusts the local feed of the sheet in such a way that the two sensors establish the same local feed, before the sheet leaves one of the selected rollers.
