  • Patent number: 9708132
    Abstract: In a method for conveying a succession of flat objects in a longitudinal direction, each object is pivoted while being conveyed at a first longitudinal displacement speed (V1) during the pivoting phase in a pivoting zone. Each flat object is conveyed at a second longitudinal displacement speed (V2) in a second zone adjacent to the pivoting zone, the second speed being different from the first speed. This sets spacing between objects in the zones before and after the pivoting zone.
