Abstract (en)
[origin: EP0857674A2] A conveying apparatus has a receiving surface for a stack of printed products lying above one another, with a conveying device adjoining the receiving surface. A vacuum roll rotatable in the conveying direction can act by means of a reduced pressure on the lower side of the printed product in order to produce the desired overlap. The upper tangential plane of the vacuum roll thereby forms a part of the receiving surface. The apparatus herein generates a stream of overlapping signatures with the overlap between adjacent signatures in the stream being uniform. Such uniform overlap generally corresponds to the distance from the upstream end of the receiving surface or signature support portion of the apparatus to the vacuum roll, and more specifically to the upstream edge of a transverse manifold slot provided in the roll. Overlapped signatures are fed by the roll to a downstream nip and blower assembly for being pulled through the nip thereof. The nip is shiftably mounted so as to adjust the size of nip space during running of the apparatus to accommodate for changing thickness of the signature material drawn through the self-adjusting nip at any one time, such as due to varying numbers of signatures being in the nip space or when thicker folded over spines are therein. The precise location at which air from the blowers is directed back upstream against the signatures can be fine tuned and preset as determined by the thickness of the signatures to be run. <IMAGE>
