Abstract

The additional patent describes a device for smooth placing of sheets (1) on the impression cylinder (3) ahead of the printing gap (5) of a sheet-fed rotary offset printing machine, in which device a lance nozzle (8), which can be directed towards the circumference of the impression cylinder (3) and extends over a substantial part of the width of the impression cylinder (3), is provided for pressing the sheet (1) on by the dynamic effect of flowing air. This lance nozzle (8) is mounted with spacing ahead of the printing gap (5) so as to oscillate about an axis (9) of oscillation parallel to the axis of the impression cylinder (3) and can be coupled to a drive which moves the lance nozzle (8) back and forth in phase with the machine, oscillating in the running direction of the sheet (1). In constrast to the principal patent, the lance nozzle (8) has a shape in which the ends are offset relative to a central region in the running direction of the sheet so that a centrally leading smoothing of the sheet (1) takes place from the leading edge to the trailing edge of the sheet and from the centre of the sheet to the two outsides. Preference is given to a lance nozzle (8) which has an arrow-type shape directed with the tip counter to the running direction of the sheet. <IMAGE>
