ABSTRACT:
Infeed devices serve to individually place in straddling formation printed signatures or sheets upon collating conveyors equipped with pusher entrainment members. There are provided a plurality of mutually parallelly extending collating conveyors arranged at a substantially uniform circumferential spacing from one another about an axis of revolution. These collating conveyors revolve about such axis of revolution. In order to obtain an essentially coincident or congruent alignment of the edges of the printed signatures or sheets during collation thereof there is provided at the region of the transfer location of each of the infeed devices an associated impact element in order to force the printed signatures or sheets against the associated pusher entrainment member.
