ABSTRACT:
The sheet-stacking apparatus stacks sheets arriving in a stream of successive sheets. A stop face configuration is pivotable, about a geometric pivot axis located at a predetermined level and oriented crosswise to the stream, between a working position wherein it stops the sheets and a position that is pivoted away from it. The system enables accurate, straight-edged stacks, both in the successive buildup of one stack and in the formation of a succeeding stack without interrupting the stream of sheets. In a first variant a carrier profile is provided, which is located above the pivot axis in the working position and past which, in the working position, stop face segments protrude downward in comblike fashion. In a second variant, a carrier profile with auxiliary stops protruding past it is disposed, adjustable in height, below the pivot axis.
