Abstract
During the gathering process, an individual signature is respectively withdrawn from several collections of identical signatures, wherein the various decollated signatures are delivered to a collecting conveyor in order to form stacks. The invention proposes that the sheets (3) of a collection (4) are transported in a direction that is essentially oriented transverse to the transport direction (F) of the collecting container (10) in the form of continuous stream feed (4) of sheets (3) that lie on top of one another in a shingled fashion, that the respective front sheet (3) is taken hold of by a conveyor (42) on its leading section such that it is prevented from turning and displaced such that it is deflected in the transport direction (F) of the collecting conveyor (10), and that the displaced sheet (3) is received by a withdrawal conveyor system (50) and additionally transported in said transport direction (F) in order to synchronously deliver the sheets (3) to the collecting conveyor (10) in the corresponding cycle. This makes it possible to reliably and carefully process sheets supplied in the form of stream feeds without intermediately storing the sheets in magazines and decollating the sheets anew from the stacks.
