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.

Vane wheel laying out device for printing products

In a rotary machine for processing a series of sheet-shaped products supplied at a rate which is synchronized with the machine cycles, a device for diverting the stream of products to processing directions in accordance with a desired mode of operation. The device includes at least one guiding tongue pivotably supported in the path of movement of the products. A cam disk attached to a driven gear is supported for rotation at a free end of a rocking arm whose other end is pivotably supported on the machine frame. A cam follower lever is spring biased into engagement with the cam disk and at its end is fixedly connected to the pivot shaft of the guiding tongue. The rocking arm is linked to a control device which either electrically or electromechanically by means of two solenoids sets the rocking arm in at least three different angular positions in dependency on the selected mode of stream diverting operation.

A synchronizing device for an electrically actuated coupling automatically coupling structural units of processing machine, includes a driving shaft and a driven shaft and two synchronizing members each connected to the assigned shaft for joint rotation therewith. A light emitter is positioned at the first synchronizing member while a light-conducting cable, receiving light from the light emitter, conducts it to a photoelectric detector connected in an electric circuit which actuates the coupling. The angular position of the first synchronizing member relative to the second synchronizing member is adjusted by clamping elements connecting the first synchronizing member to a driving gear of the driving shaft.

A continuous wire feed arrangement for feeding wire to a stapling apparatus or the like comprises two nozzles respectively located along paths along which wires may be fed to a device for cutting and transmitting cut wire portions to the stapling apparatus. The wire feed is carried out at any time only to one of the nozzles. Each of the wires is withdrawn over a guide roll and a wire feed device from a wire reel. The respective fed wire closes thereby over the guide roll an electric circuit. When this circuit is interrupted due to running out of wire on one of the wire reels, or due to interruption of the feed of the one wire, the transport of the other wire is automatically initiated. The changeover of the wire transport from one to the other wire reel is carried out by electromechanical elements. In this way a continuous uninterrupted wire supply to the cutting and transmitting device is assured.
