The invention provides a method and a system for conveying products, said system comprising a conveyor (4) with a drive device for moving products (3), a supply conveyor (10), which connects to the conveyor (4) for moving products (2) in a supply direction (18) and transferring these products (2) to the conveyor (4), a control device (20) to control the drive device of the supply conveyor (10) in such a way relative to the drive device of the conveyor (4) that a product is transferred from the supply conveyor (10) at a predetermined position onto the conveyor (4). The supply conveyor (10) comprises a positioning portion (24) to speed a product (2) up or to slow it down. The system further comprises a blowing device (32) for generating in operation, under the influence of the control device (20), an air stream from above the carrying surface (14b) of the supply conveyor (10) in the direction (18) of the carrying surface (14b) at the location of the positioning portion (24), for forcing, in operation, products (2) against the carrying surface (14b).
