Abstract: The invention relates to a testing device 10, that can be a component of a feeding device to feed coin blanks 11 to a coining press or a minting station 12. The testing device 10 has a contactless measuring first sensor device 30 and/or a second sensor device 40. Every sensor device 30, 40 that is present controls an associated removal device 32 or 41. Each sensor device 30, 40 detects a certain property of the coin blank and compares it with a corresponding standard specification. If an unacceptable deviation from the specification is detected, the sensor device 30, 40 in question controls the respective associated removal device 32, 41 to discharge the coin blank from a main conveyor device 13 which transports the coin blanks from a feeding end 14 to an exit end 15.

Abstract: The invention relates to a method and a device for feeding flat objects overlapping in slats, particularly metal sheets, at least to a front edge stopper of a processing machine, particularly a tin printing machine or a tin-plate varnishing machine, with a first conveyor on which the objects lie.
