Abstract
1230113 Transferring developed electrostatic images RANK XEROX Ltd 7 Oct 1968 [12 Oct 1967] 47385 Headings B8R RL R247 R248 R222 R276 and R279 A sheet 12 which has received a developed electrostatic image from a seerographic drum 10 is stripped from the drum by the combination of a detacking corotron 20 and an air blast from a manifold 22. The corotron 20 produces a charge opposite to the electrostatic charge provided by a transfer corotron 16 to cause the leading edge of the sheet 12 to be repelled from the drum. The detacking corotron 20 may have an impressed A.C. voltage or an adjustable D.C. bias. Nozzles (35) Fig. 2 (not shown) direct air against the undersides of the stripped sheets to maintain contact with a vacuum conveyer 21.
