Abstract
The invention relates to collecting and conveying devices for stacks of sheets (3), comprising a collecting station (1) in which a corresponding number of sheet stacks (3) are formed simultaneously from several imbricated flows (2) of sheets which are guided adjacent to each other, a transversal transporter (4) which is arranged at a distance behind the collecting station (1) for transporting the finished stack of sheets (3) in a manner transversal to the direction of transport of the sheets in the collecting station (1) and a transfer device (5) which is used to transport the stack of sheets (3) from the collecting station (1) to the transversal transporter (4). According to the invention, a carriage (9) that can be displaced over a given path in a manner that is synchronous with the transversal support (4) is arranged adjacent thereto. Also, a row of holding down clamps (10) is secured to said carriage and the holding down clamps can be lowered on the stack of sheets (3) located on the transversal transporter (4).
