Abstract

1322854 Feeding sheets POLYGRAPH LEIPZIG - KOMBINAT FUR POLYGRAPHISCHE MASCHINEN UND AUSRUSTUNGEN VEB 12 June 1971 27620/71 Addition to 1307664 Heading B8R [Also in Divisions G1 and G4] In a sheet processing machine comprising means for feeding a sheet to a reference location defined between two reference lines 1, 2 one parallel to and the other perpendicular to the sheet feed direction, the position of the sheet is sensed by a plurality of photo-electric receivers 4 spaced along a line which extends across a corner of the reference location and intersects the two reference lines, and may be positioned at right angles to a diagonal extending from said corner.
