Abstract

A device for the generation of a shingled stream of flat, flexible objects along a conveyor path, wherein successive objects develop an overlap with a length, includes a first and a second suction and conveyor device having a first and second unit, respectively, and each having at least one conveyor belt. The first and second units are each configured to generate a vacuum through a whirlwind to attract at least one of the objects and are each disposed in a casing having a suction aperture. The second suction and conveyor device is 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 and is disposed at an angle relative to the direction of the conveyor path. The first and second suction are separated by a spacing in a transversal direction.
