Method and device for the generation and/or conveyance of a shingled stream of flat, flexible objects

A method for generating and conveying a shingled stream of flat, flexible objects along a conveyor path, the method comprising:

• using, a first device for generating the shingled stream of flat, flexible objects, the first device comprising:
• a first suction and conveyor device including a first unit and at least one conveyor belt, the first unit being configured to generate a vacuum through a whirlwind to attract at least one of the objects and being disposed in a casing having a suction aperture;
• and
• a second suction and conveyor device disposed downstream from the first suction and conveyor device in a direction of the conveyor path with a mutual offset corresponding to the length of the overlap, the second suction and conveyor device being disposed at an angle relative to the direction of the conveyor path, the second suction and conveyor device including a second unit and at least one conveyor belt, the second unit being configured to venerate a vacuum through a whirlwind to attract at least one of the objects and being disposed in a casing having a suction aperture,
• wherein the first and second suction and conveyor devices are disposed on different sides of the conveyor path, respectively above and below the flat, flexible objects, and separated by a spacing in a transversal direction of the conveyor path,
• using a second device for conveying the shingled stream of flat, flexible objects disposed downstream in the direction of the conveyor path from the first device, the second device comprising:
• at least three third suction and conveyor devices disposed along the conveyor path successively in a direction of the conveyor path, each of the suction and conveyor devices including a third unit and at least one conveyor belt the third units each being configured to generate a vacuum through a whirlwind to attract at least one of the objects and being disposed in a easing having a suction aperture, wherein velocities of the conveyor belts in each of the third suction and conveyor devices are controllable individually and independently from one another, and
• adjusting a length of an overlap of consecutive objects.
