Abstract
A method and an apparatus for controlling the traveling direction of a piece of folded material in the feed path of a folding machine. A first roller nip is used to ingest the folded material into the front end of a turn chute. If the traveling direction is to be maintained, the folded material is allowed to move out through the rear end of the turn chute. If the traveling direction is to be reversed, a stop is used to block the rear end in order to keep the leading edge of the ingested folded material from leaving the turn chute through the rear end. At the same time, the trailing edge of the ingested folded material is caused to engage in a second roller nip located in the front end of the turn chute, in order for the second roller nip to move the folded material out of the turn chute, thereby reversing the traveling direction of the folded material.
