ABSTRACT:
The present invention relates to a deceleration device for flat products, such as signatures. A deceleration device has a plurality of seizing elements attached thereto for seizing signatures at their respective leading edge while the signatures are emerging from a conveying device. The leading edge of a signature travels on a first path, whereas the trailing edge of the signature travels on a second path, which creates a larger air-drag coefficient on the signature than the first path.
