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.

The invention relates to a method for blowing away particles of glue in a strip-gluing unit for folding box forming machines for gluing box blanks. Compressed air is blown from the side of a gluing disc of the gluing unit at an acute angle obliquely towards the direction of travel of the blank at the height of the nip between the blank and gluing disc so that on account of the high speed of the blanks and gluing disc, particles of glue which are thrown off are removed on the shortest path, without these particles splashing on the blanks and machine parts. The air is blown by an air-guide member, which comprises an air chamber, which is connected by lines to a source of compressed air. Starting from the air chamber is a bore whose axis is directed at the height of a nip at the acute angle. The air-guide member is attached in the folding box sticking machine independently of the gluing unit and is seated laterally beside the gluing disc and serves simultaneously to support the travelling blanks.
