ABSTRACT:
A vane wheel laying out unit for sheet-by-sheet laying out of printing products for high speed roller rotary printing machines comprises a vane wheel including a shaft and a plurality of thin vane star discs fixedly mounted on the shaft in a lamellar fashion at a distance from one another, a band supply unit associated with the vane wheel for supplying printing products to the latter, a plurality of stationary blowing air nozzles each associated with a respective one of the vane star discs of the vane wheel so that a direction and an intensity of blowing air stream from the blowing air nozzles influence a friction between a printing product falling in one vane and an outer side of another vane which is arranged after the one vane, the vane star discs, the band supply unit and the blowing air nozzles are arranged in their position relative to one another so that the printing product before an ejection of its rear edge from the band supply unit is blockable by the one vane which receives the printing product from the blowing air streams of the blowing air nozzles, during ejection of its rear edge approximately one half of its length is received in the one vane and after ejection of its rear edge it is braked by the blowing air streams of the blowing air nozzles, a stripper associated with the vane star discs of the vane wheel and formed as a rack adjustably engageable in intermediate spaces between the vane star discs, and a pressure air conduit supplying the blowing air nozzles with a pressure which it controllable in dependence of a machine speed, the vane star discs having a shape which is optimal for braking during receiving the printing product in the vane star discs and during acceleration of the printing product during stripping off by the stripper.
