A device for forming stacks of sheet products, in particular of paper products, may include the paper products being supplied in an input stream by a feed conveyor to a transfer section. The device may also include at least two set-down tables each including a set-down surface for receiving stacks of the supplied paper products. The set-down tables may move along a circuit-like table-circulating path and may be flexible at least in some segments to conform to shapes of curvatures located in at least some parts and subregions of the table-circulating path. As a result, it is possible for the set-down tables to be guided into the curvatures with a leading front side edge of each of the set-down tables being a leading edge in a circulating direction of the set-down tables. The stacks of stacked paper products may then be transported away from a delivery section by a removal conveyor.

An apparatus for winding or unwinding material webs onto or from a winding core ( ) has a bearing device ( ) and a drive device (9) for driving the winding core ( ) that is rotatably mounted in the bearing device ( ). The drive device (9) comprises a drive ( ) and a torque-transmitting device ( ) from the drive ( ) to the winding core ( ). In order to achieve the smallest possible winding-core diameter and, nonetheless, to achieve an adequate winding or unwinding speed, the torque-transmitting device ( ) comprises a toothed-belt reduction gear mechanism ( ).
