Abstract
A device for effecting the positionally accurate conveyance of flat articles to be sorted to an input device for a sorting conveyor has a draw-off unit and a feed unit. The draw-off unit periodically separates the flat articles to be sorted, and feeds them in separated form onto a conveyor line. The feed unit transfers the separated articles with a defined advance to the input device after these articles have reached a predetermined conveyance location of the conveyor line. A section of the conveyor line immediately preceding the predetermined conveyance point is arranged substantially vertical and includes a pair of belts for guiding the article to be sorted, with one belt of the pair running around two rollers and the other belt of the pair configured to be raised for a predetermined time.
