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 |
