Abstract

A device for collecting a trailing edge of a sheet for a sheet delivery with a non-step auxiliary piling device in a sheet-fed rotary printing machine includes a plurality of collecting fingers all disposed at the same level at distances mutually spaced from one another, a motorized drive for moving the collecting fingers forwards and backwards, parallel to sheet travel, in a guide channel, a suction roller in operative proximity with the collecting fingers, and sheet pile stops for the trailing edges of the sheets, the sheet pile stops extending upwardly beyond the level of the sheet pile to the suction roller, the collecting fingers being disposed beneath the suction roller and between the pile stops, the motorized drive including a common drive member with mechanical transmission members coupled with the collecting fingers.
