Abstract: An arrangement (100) for handling flat elements (202), in particular paper elements (202). A guiding structure (101) is provided, along which a flat element (202) is guidable and transportable along a transport direction (T). A hold-down element (102) is coupled to the guiding structure (101) for holding down the flat element (202) to the guiding structure (101). The hold-down element (102) has a support section (103) on which the flat element (202) is supportable. The hold-down element (102) extends along an extending direction (116) having a component perpendicular to the transport direction (T), wherein suction holes (104) are arranged along the extending direction (116). A suction unit (110) includes a suction opening (111) coupled to the suction holes (104) of the hold-down element (102), an air inlet (112) and an air outlet (113), wherein the suction unit (110) directs air from the air inlet (112) to the air outlet (113) for generating an air flow (114). The suction opening (111) is formed and arranged such that the air flow (114) passes the suction opening (111) so that air flow (114) entrains air through the suction opening (111).

Abstract: A sheet material processing unit (10) is described. It comprises an upper tool (18) and a lower tool (14), wherein the upper tool (18) and the lower tool (14) are configured to interact with each other in order to process sheet material (26). Furthermore, a camera unit (40) is provided which is arranged such that it is able to simultaneously capture a portion of the upper tool (18) comprising a first opening (28) and a portion of the lower tool (14) lying behind the first opening (28) for aligning the tools (14, 18). The sheet material processing unit (10) additionally comprises a first and a second set of light sources which are distinct from one another and are configured for subsequently illuminating the portions to be captured. Moreover, methods for assessing an alignment of the upper tool (18) with respect to the lower tool (14) and with respect to the sheet material (26) are presented.
