An apparatus for driving a roller of a printing press includes a main motor configured to drive the roller through a first gear wheel and a first freewheel, and an auxiliary motor configured to drive the roller through a second gear wheel and a second freewheel. A brake that is different from the main motor, for example a band brake, is configured to brake the roller during overrunning of the roller following a machine stop signal. A printing press having the apparatus is also provided.

A method of winding a web band in a machine for processing printing materials, including controlling the winding as a function of a diameter of a roll formed by the web band, as the diameter changes during the winding, includes determining, by a first sensor fastened to a frame of the machine, the position of a peripheral surface of the roll relative to the frame of the machine, and determining, by a second sensor fastened to the frame of the machine, the position of one of a center of the roll and of a peripheral surface of a spindle carrying the roll, relative to the frame of the machine; a winding device for performing the method; and a printing-material processing machine, such as a printing press, having the winding device.
摘要:
A current connection suitable for transferring high-frequency, high-amp current consists of a stationary feed line part (2) and a rotational part (4), each of which is connected to paired conductor rails (6, 8; 6', 8'). The conductor rails (6, 8; 16, 18), connected at one end to a power generator and at the other end to the stationary feed line part (2), consist essentially of at least two parallel conductor rails, which are kept a certain distance apart by means of an insulator (5a). As a result of flexible power conductors (10, 10'), electrically conductive manner to the circular periphery of the outer conductor ring (14), the other end to inner conductor ring (15), the rotational part (4) can be rotated with respect to the stationary feed line part (2) in correspondence with the length of the current conductors (10, 10', . . . ; 11, 11', . . . ). The conductor rail (16, 18), consisting of two individual conductors (16, 18), is connected electrically to the individual poles of the rotational part (4) and projects at the other end through a leadthrough plate (20) into a sealable process chamber, in which, by means of the rotatable power connection, a melting device can be supplied with operating current. By means of the power connection, currents of up to I=20,000 A at voltages of up to U=500 V and at operating frequencies of up to f=10 kHz can be transferred.

A method for operating a cleaning apparatus, having a trough and a brush disposed in the trough, in a printing press, includes first, second and third steps. In the first step, a cylinder of the printing press is cleaned by the cleaning apparatus, with the brush bearing against the cylinder. In the second step, the brush is moved away from the cylinder, and a level of a liquid in the trough is changed, resulting in the liquid being brought into contact with the brush. In the third step, the brush is cleaned by the liquid in the trough. A printing press for carrying out the method is also provided.

Example embodiments relate to a server for providing remote storage space to users. The server may include a mechanism that allocates a portion of storage space in the storage area in response to a request from a first remote user. The server may also include a mechanism that maintains storage records, the storage records identifying a user currently granted exclusive access to the portion of storage space. Furthermore, the server may include a mechanism that processes access requests to determine whether a remote user requesting access to the portion of storage space is the user currently granted exclusive access. Related clients, methods, and machine-readable storage media are also disclosed.

摘要:
For the production of particles from castings (10) of metals from the group of the lanthanides, aluminum, boron, chromium, iron, calcium, magnesium, manganese, nickel, niobium, cobalt, titanium, vanadium, zirconium, and their alloys, which have solidified in an oriented manner, especially for the production of materials from the group of magnetic materials, hydrogen storage elements (hydride storage elements), and battery electrodes, a melt of the metal is applied in a nonreactive atmosphere to the inside of an at least essentially cylindrical cooling surface (9) according to the principle of centrifugal casting. The cylinder rotates at high speed around a rotational axis, and the melt is cooled proceeding from the outside toward the inside with an essentially radial direction of solidification. The hollow casting (10) is then reduced to particles. The melt is preferably applied to the rotating cooling surface (9) in a thickness which is no more than 10%, and preferably no more than 5%, of the diameter of the cooling surface (9), and the diameter of the cooling surface (9) is at least 200 mm, and preferably at least 500 mm.
