摘要

A device (30) for removing trim waste (24) by suction in a printing-substrate processing machine (10), including at least one air duct (28) having at least one suction opening (26) and one apparatus (34) for producing an air flow (32) through the suction opening (26) into the air duct (28), the air duct (28) having at least one additional opening (42) which has a closing element (44) which enables the size of the additional opening (42) to be variably adjusted. The size of the at least one additional opening (42) of the air duct (28) is adjusted in such a way in accordance with the present invention that the apparatus (34) is operated at a constant load.
