Abstract: The invention relates to a method for alignment of individually moved sheet-shaped materials with two individually controlled frictional wheels (A, B), wherein the frictional wheels (A, B) carry out speed changes continuously during the entire process of the alignment according to a control function and in this way achieve a change from the state parameters input angle (?in) and input speed (vin) of the sheet-shaped material, to the state parameters output angle (?out), output speed (vout), X shift (xshift) and Y shift (Yshift).

Abstract: A device for alternate transport of sheet-shaped materials (1) has at least one frictional wheel (41, 42) as well as a housing (20, 21, 22), an actuating element (30), a drive (34) for the actuating element (30), a control (70) for the drive (34) and at least one driven transport element (50, 52), whereby at least one frictional wheel (41, 42) is mounted so that it can rotate at the end of a spring plate (10), whereby the spring plate (10) is mounted with respect to the housing (20, 21, 22) and the actuating element (30) in such a way that the spring plate (10) can be brought into a first active bending state and into a second passive bending state by means of the actuating element (30), whereby in the active bending state the at least one frictional wheel (41, 42) is in working connection with the transport element (50, 52) and in the passive bending state it is not.

Abstract: The device for removing flat articles from a stack comprises at least one roller which contacts the uppermost article of a stack and is rotatable about a shaft and whose circumferential surface is covered by a layer consisting of a resilient material. The resilient layer positioned on the circumferential surface of the roller includes a number of suction cups. The roller is designed as a hollow roller which includes a mechanical device by which the suction cups in the resilient layer on the circumferential surface of the roller can be operated by partial deformation of said resilient layer. The suction cups are formed by depressions in the resilient layer on the circumferential surface of the roller, said depressions cooperating with one bore each in the wall of the roller.

Abstract: The apparatus according to the invention comprises a collector bin (2) for fed sheets (5) that is made up of a sheet support (4) and a sheet stop (12). A retaining apparatus (8) for the fed sheets (5) is provided facing the sheet support (4), and a stop finger (10) can be pivoted into the paper path. A jogger wheel (6), with which the fed sheets (5) can be transported toward the sheet stop (6), is installed above the sheet support (4) rotatably about a shaft (A). A holding element (14) for the stop finger (10) can be moved on the shaft (A) independently of the rotary movement of the jogger wheel (6), and a stopgap closure element (16) is also arranged on the holding element (14) in such a way that the stop finger (10) or the stopgap closure element (16) can be introduced into the paper path.

Abstract: The subject is a device for guiding and holding down of sheets supplied singly by a conveyor device to a sheet stack formed in a storage container, said device comprising a two-armed lever pivotably mounted about a bearing point located above the sheet conveying track.

Abstract: A device is disclosed for transferring electrical signals and electric energy to a data memory (6) of a cassette (1) for radiation-sensitive recording material (11), the memory being connectable to a signal processing unit (4) and a power source (5) of a cassette identification apparatus (2). Means are provided between cassette (1) and cassette identification apparatus (2) for radio-frequency and galvanically insulated transfer of the signals and the electric energy. Such means feature a coupling device (3) having capacitive, inductive or opto-electric coupling elements that are resistant to corrosion, soiling and wear. Furthermore, the means comprise a signal processing unit (4) having signal transmitter circuits (41, 42, 43) and signal receiver circuits (44, 45, 46) for radio-frequency signals, and a power source (5) having an energy transmitter circuit (52) and an energy receiver circuit (53) for a radio-frequency voltage.
