(57) There is described a delivery unit (20; 20') for coupling to a sheet printing or
processing unit of a sheet-fed printing or processing machines comprising several
delivery modules forming a plurality of delivery piles (21, 21.1 to 21.3, 21.1 to
21.5) disposed one after the other along a sheet delivery path, a transporting system
(27, 27.1, 27.2, 27a, 27b) for transporting the sheets along the sheet delivery path,
and sheet-delivery control means for selectively delivering the sheets in any one
of the said delivery piles. The delivery modules are built in a modular fashion, each
delivery module being constructed as an independent delivery module with individual
sheet transfer means (211, 212, 218) for assisting transport of the sheets along the
sheet delivery path and individual control means (215) for selective delivery of the
sheets in the delivery pile of the delivery module, the delivery unit further comprising
an adaptation unit (22) for adapting the delivery piles to the printing or processing
unit. Each delivery module includes a pile conditioning device (217) for aligning
sheets which are successively delivered to the delivery pile into a uniform pile of
sheets, which pile conditioning device (217) is adjustable lengthwise and Widthwise
to the dimensions of the sheets
