Abstract: To provide an apparatus for sorting sheetlike data carriers which firstly has a compact and ergonomically optimal design and secondly permits the use of compact and cost-effective test devices, it is proposed that the input pocket (2) and the output pocket (12-15) are designed and oriented with respect to the front side (1) of the apparatus such that the long sides of the data carriers (3) face the operator. The singling device (19) and the transport system (4) transport the data carriers through a test device in the direction of their long sides.

Abstract: The present invention relates to an apparatus for singling flat material to be conveyed having a suction device, with openings in the suction device defining an area within which the suction device grasps the material to be singled. Known singling devices have in particular the disadvantage that operation of the suction device produces a high noise level which is felt to be very unpleasant. The present invention provides a shifted arrangement of the suction openings which leads at least to partial elimination of the noise during shifted activation of the suction openings.

This apparatus is able to attain a high throughput even with different sheet qualities while guaranteeing high functional safety.

Abstract: The method involves measuring data of a sheet material first being detected by means of a sensor, the sensor then deriving one or more measuring results from the data. Using a sorting tree a sorting class for the sheet material is derived from the measuring results of the sheet material. In each sorting node of the sorting tree a domain is fixed for at least one measuring result. The domains of a measuring result in a sorting node are selected so that they are either a subdomain or equal to the domain of the corresponding measuring result of the assigned, higher sorting node. The sheet material is transported to a destination in accordance with the derived sorting class for the sheet material.
