Patent ID: 6918588

Claim:
A device for separating an imbricated formation of printing products having a format height (H) continuously conveyed in a feed direction (F) while partially overlapping in an imbricated manner, into a succession of spaced printing products, comprising: a first conveyor for said imbricated formation driven at a first velocity (v 1 ); a second conveyor for said spaced products arranged after said first conveyor and driven at a second velocity (v 2 ) which is higher in relation to the first velocity; and a de-imbricating device for accelerating the leading printing product of the imbricated formation of the first conveyor to the second velocity (v 2 ) and for maintaining the imbricated arrangement of the following printing products being conveyed in the imbricated formation at the first velocity (v 1 ); wherein the de-imbricating device includes two suction belt conveyors with associated belt deflectors, arranged one behind the other between the first and second conveyors, the first suction belt conveyor driven at the first velocity (v 1 ), the second suction belt conveyor driven at the second velocity (v 2 ); the first suction belt conveyor having a suction field which is displaceable along the feed direction (F) with respect to the format height (H) of the printing products; and the second suction belt conveyor having a suction field which is arranged at the start of the second suction belt conveyor directly after the belt deflector of the second suction conveyor, as seen in the feed direction (F).
