Abstract: A method of grouping sheet units, which belong together in sheet groups, a sheet stream comprising two superposed sheet units each by means of a grouping unit, a grouping unit for a sheet handling system, and a sheet handling system that allow a high processing speed and a high cycle efficiency of a sheet handling system are disclosed. A sheet unit can be held back in the grouping unit. Depending on whether the downstream subsequent sheet units transferred into the grouping unit belong to a sheet group, the held-back sheet unit can be released by itself and together with one or together with both downstream subsequent sheet units.

Abstract: In a method for forming groups of sheets from a plurality of sheets, initially two sheets are provided, respectively. The sheets are transferred into a common sheet track. If the sheets provided belong to the same group of sheets, these sheets are transferred into a collating station. Otherwise, one of the sheets is transferred into the collating station and the other one of the sheets is retained at a stop location.

Abstract: In a method and a device for forming groups of sheets consisting of one or of a plurality of sheets, a predetermined number of sheets is first supplied to a first position in a collecting station so as to form a first group of sheets. As soon as the first group of sheets has been formed, it is moved from the first position to a second position in the collecting station, and then a predetermined number of sheets is moved to the first position in the collecting station so as to form a second group of sheets.
