The seder comprises a perforated cylindrical metal drum (1) connected to a suction source so that its holes (3) pick up one seed (8) each from a hopper (5) and deposit them subsequently at the bottom of the drum a layer of film, paper or substrate (11) moving on a conveyor belt (10) to make a seed strip. The drum rotates at a different speed to the moving layer, preferably a higher speed, so that the seeds are applied with a sliding movement. |
