Abstract
Flat articles such as letter envelopes or letter envelope blanks or the like are aligned for further processing by transporting the articles through an alignment path with the help of a pulling mechanism that seizes or entrains each individual article along its leading edge as viewed in the transport direction and moves the article by pulling the article against a stop member or members which are also moved, but with a slower speed than the pulling of the article. Once the leading edge of the article bears against the stop member or members, the article is aligned and ready for further processing. The entraining or seizing takes place in an area positioned substantially centrally along the leading edge of an article between ends of the leading edge of an article.
