Abstract
The conveying apparatus for a flat article, particularly a cardboard blank, paper sheet or the like, comprises two driven endless belts running over guides positioned opposing each other between which the article is clamped during transport. The endless belts are guided on base surfaces of beds of the guides having a wavelike longitudinal cross section in the conveying direction with a plurality of wave troughs and peaks. A plurality of lateral supporting members are attached to each of the beds. The wave crests of one of the guides are positioned staggered with respect to the wave crests of the other guide and opposing the wave troughs of the other guide. Furthermore the endless belts are either elastic in the conveying direction or a tension provider is mounted engaging each of the endless belts.
