  • Method and apparatus for determining a sub-group of a group of sheets in a stream of sheets
    Patent number: 8366093
    Abstract: A method for determining a subgroup of a group of sheets in a sheet stream starting from a group start of the group comprises determining the subgroup end of the subgroup based on a sheet state parameter. The subgroup is determined by the group start and the subgroup end and comprises a variable number of sheets. The sheet state parameter determines which sheet in the sheet stream is a group end of the group of sheets.

  • Method and Device for Transporting Paper Within a Paper Handling Installation from a First Conveyor to a Second Conveyor
    Publication number: 20110169217
    Abstract: In a method and a device for transporting paper within a paper handling installation from a first conveyor to a second conveyor, the second conveyor has a velocity which at least partially follows a drive curve of the first conveyor. A frictional force between the second conveyor and the paper is set to a first value when the first conveyor and the second conveyor are in engagement with the paper. The frictional force between the second conveyor and the paper is set to a second value, which is higher than the first value, when the papers is conveyed by the second conveyor.

  • Equipment arrangement
    Patent number: 6175502
    Abstract: An equipment arrangement for switch, computer and server cabinets or racks comprises a monitor/flat screen, a keyboard and a signal switch in a common slide-in module or in two individual slide-in modules. The monitor/flat screen can be pivoted up or folded out in an extracted operating position. In the case of a module having one height unit of the 19 inch design the signal switch is positioned between the keyboard and the monitor/flat screen. In the case of a common module with a height of approximately two height units or two separate modules having in each case a maximum height of one height unit, the keyboard and signal switch are located in one plane and above the latter is located a monitor/flat screen.
