A stamping press for stamping a round blank. A ram movable in a stroke direction and in an opposite return stroke direction carries a first stamping tool. A second stamping tool and a stamping ring are supported on a press framework. The stamping tools and a stamping opening formed by the stamping ring are aligned along a working axis. An ejector device serves to eject a stamped round blank from the ring opening. It comprises an ejector pin supported on an actuating device that is movably coupled with the ram. During a return stroke of the ram the ejector pin can apply a force on the second stamping tool in order to press the round blank out of the stamping ring. In a ram movement in the stroke direction the actuating device departs from the second stamping tool and no ejector pin force is applied on the second stamping tool.

A transport device and a method for producing a coin with use of the transport device. The transport device is used to transport blanks to a minting station. A drivable first transport part having a plurality of first transport pockets is provided. A first clearance exists between the outer contour of the blank and the inner contour of the first transport pocket. The transport device has a second transport part having a plurality of second transport pockets. A second clearance is provided between the outer contour of the blank and the inner contour of the second transport pocket. The second clearance is larger than the first clearance. The blanks are transferred at a transfer location from a particular first transport pocket into a second transport pocket. The blanks are transported in the second transport pocket to the minting station, and a coin is minted there from the blank.

An outer ring () is first transported to an insertion point (E) in the feed device (). At the same time, a circular blank ring () is brought into a starting position (P) in the feed device. The circular blank ring () is first aligned coaxially with respect to an axis (A) using a centering body (). The circular blank ring moves solely radially with respect to the axis (A). The circular blank ring () is then inserted into the hole of the outer ring (). During this movement, the circular blank ring is aligned coaxially with respect to the axis (A) preferably using a centering channel (). The circular blank ring () carries out a superimposed movement in the axial direction (V) and in the radial direction radially with respect to the axis (A).

A forming device and a method for forming an inner rim of an annular round blank. The forming device has a lower tool with a movable die and an upper tool arranged opposite the lower tool along a working axis A. By means of the die, the annular round blank is moved out of a transport plane T and into a forming position U towards the upper tool and into the interior of a holding sleeve. Subsequently, the inner rim is formed with the aid of a forming tool. After forming, the annular round blank is moved out of the forming position U and back into the transport plane T by means of the lower tool and/or the upper tool. The forming device and the forming method can occur while the round blanks are being fed to an embossing station while being transported by a revolving table.

The invention relates to a testing device, that can be a component of a feeding device to feed coin blanksto a coining press or a minting station. The testing devicehas a contactless measuring first sensor deviceand/or a second sensor device. Every sensor devicethat is present controls an associated removal deviceor. Each sensor devicedetects 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 devicein question controls the respective associated removal deviceto discharge the coin blank from a main conveyor devicewhich transports the coin blanks from a feeding endto an exit end

Testing device for testing coin blanks

An apparatus and a method for inserting a non-round circular-blank core into a non-round hole of a circular-blank ring to create a circular blank. A transporting device transports the circular-blank ring to an insertion location. A feed device transports the circular-blank core to the insertion location. The circular-blank core is positioned on the hole of the circular-blank ring and inserted into the hole with the aid of a pushing-in device, which applies a pushing-in force. If the non-round hole is not in alignment with the non-round circular-blank core, the circular-blank core and the circular-blank ring are rotated relative to one another at the insertion location by generation of the pushing-in force. The circular-blank ring is preferably moved, by the pushing-in force, onto an alignment mandrel, which causes the circular-blank ring to rotate in its circumferential direction until the contours of the circular-blank core and of the hole are in alignment.
