摘要： A device for automatically performing nonstop pile changing in a delivery of a printing press, preferably having a high printing speed, includes a separator sword movable sidewise between two sheets for forming a gap therebetween, and supporting an upper one of the two sheets at a trailing-edge region thereof until an auxiliary pile carrier has reached an inserted position thereof The separator sword cooperates with a restraining or holding device formed as a separator wedge, so that the separator wedge is slidable under the separator sword and firmly holds the upper sheet at the trailing-edge region thereof by suction until the auxiliary pile carrier has been inserted
