  • Patent number: 5503387
    Abstract: A device for conveying individual printed products to a second conveying track from a staggered flow of printed products on a first conveying track. A step is formed between the first conveying track and the second conveying track. The second conveying track branches off from the first conveying track at the step and has a front end disposed adjacent the step. The device includes a carriage disposed on the second conveying track and adapted to assume an oblique movement toward and away from the step. The carriage includes a flap disposed thereon. The flap can be pivoted into and out of an effective area of the first conveying track for engaging and disengaging individual products from the staggered flow.

  • Patent number: 5503386
    Abstract: A downward-leading step is disposed between a first and second conveying track, where a first scale-shaped flow is spread open and transferred into a second, deflected scale-shaped flow. Pressure rollers are disposed ahead of and behind the step, which rest against the top of the first or second scale-shaped flow and constitute means for aligning the second scale-shaped flow. In this way the exact evenness and directional consistency of the deflected scale-shaped flow is ensured without a lateral guidance panel.
