The invention relates to a sheet transport device () comprising a first and a second opposing transport units (), each comprising at least one circulating conveyor belt () and one vacuum suction device () that is in relation with the conveyor belt, said vacuum suction devices being individually actuatable so as to attract a sheet (), located between the transport units, to the one or the other conveyor belt. Such a sheet transport device is used, for example, in a printing machine. The invention also relates to a method for transporting a sheet to this sheet transport device.

Sheet transport device

For a device for the alignment of sheets, which comprises at least one first and one second driving roller () and at least one pressure roller (), as well as at least one first and one second rotary drive () for rotating said first and second driving rollers (), respectively, about an axis of rotation (), a simple and cost-effective setup is achieved by at least one displacement drive for shifting at least the driving rollers () along the axis of rotation in such a manner that there is a change of distance between the driving rollers.

Device and method for the alignment of sheets

The invention relates to a device for depositing sheets in a machine that preferably processes sheets by graphic means, in particular for a printing machine, preferably for an electrophotographically operating machine, comprising at least one deposit tray for depositing and preferably also for stacking processed sheets. Furthermore, the invention relates to a deposit tray for a device of the aforementioned type. The object of the invention is to provide a device or a deposit tray of the aforementioned type, which permits a controlled depositing and stacking of sheets, in particular, at greater sheet-processing speeds, and, preferably, in a cost-effective manner. In accordance with the invention, this object is achieved in that a deposit surface of the deposit tray is arranged, or can be arranged, at an angle that deviates from the horizontal.

Device and tray for depositing sheets

A paper transportation trolley with first guide members on the paper transportation trolley and second guide members on a coupling device of the printing machine for locking the paper transportation trolley to, and releasing it from the printing machine. The paper transportation trolley is movable over the coupling device, the first guide members sliding over the second guide members and the paper transportation trolley is connected to the coupling device by a retainer device.
