Abstract

A device for aligning flat objects, in particular mail items, has a base face, a side wall, and at least one spindle thread, which is let into the base face. The spindle thread is embodied to transport flat objects lying on the base face in a conveyance direction, thereby pushing them against the side wall. The spindle thread has at least one aligning region. Each aligning region is subdivided respectively into a decompression segment and a compression segment. The pitch of the spindle thread increases along the conveyance direction in each decompression segment and decreases in each compression segment.
