Abstract: A computer-implemented method for securely transferring a secret from a source computing component to a target computing component, wherein the source computing component and the target computing component are part of a secure computing environment is disclosed. The method comprises upon the source computing component receiving from the target computing component a signed attestation document, verifying, by the source computing component, an authenticity and content of the attestation document, and upon a successful verification of the authenticity and the content, transferring, by the source computing component the secret to the target computing system. Thereby, the attestation document is attesting that the target computing component is compliant to an update governance rule.

Abstract: A method for carrying out an automatic can changing process at a spinning station of a spinning machine uses a movable can change. At the spinning station, a supply device delivers a sliver in a delivery direction from a sliver can positioned underneath the spinning station. The sliver is clamped with a clamp on the can changer and, once clamped, the silver is separated. after separation of the sliver, the supply device is driven counter to the delivery direction such that a sliver residue remaining at the spinning station is returned by the supply device and ejected from the spinning station.

Abstract: A method carries out an automatic can change process at a spinning station of a spinning machine where a sliver is delivered to a spinning device from a sliver can positioned underneath the spinning station using a movable can changer that includes a can gripper. A length of a sliver residue is predefined and stored. Once the predefined length of the sliver residue length has been reached, the sliver is separated while production of a yarn from the sliver is underway at the spinning station. The sliver is clamped at the sliver can with a fixed clamp on the can changer, wherein separation of the sliver is performed by, with the can changer, removing the sliver can with the clamped sliver from the spinning station, or additionally clamping the sliver with a movable clamp on the can changer and moving the movable clamp relative to the fixed clamp.

Abstract: A spinning machine and method separate a sliver delivered out of a sliver can at a spinning station of the spinning machine. The sliver is delivered out of the sliver can with a supply device at the spinning station in a delivery direction to a spinning device, and is guided by a sliver guide between the sliver can and the supply device. The sliver is clamped in the supply device at the spinning station. In order to separate the sliver, the supply device is driven counter to the delivery direction, wherein the sliver is returned by the supply device and, as a result, the clamping of the sliver in the supply device is released.

Abstract: A spinning machine and method of operation include a plurality of adjacently arranged workstations, each workstation having one of a spinning device or a suction nozzle to which a process vacuum is applied during spinning operation. A vacuum duct extends along the workstations for supplying the spinning devices or the suction nozzles with the process vacuum. A maintenance unit is displaceable along the workstations, the maintenance unit including a pneumatic working element and a vacuum line to supply the pneumatic working element with vacuum. A closeable connection opening is at each of the spinning devices or the suction nozzles, the connection opening connected to the process vacuum. The maintenance unit includes a suction head that is advanceable toward the connection opening and is connected to the vacuum line.

Abstract: An open-end spinning machine and control method are provided for cleaning a spinning rotor of a spinning device in which at least one cleaning measure is carried out on the spinning rotor with the aid of a pneumatic or a mechanical cleaning device. With a control unit associated with the open-end spinning machine, settings are specified for the cleaning device to carry out the cleaning measure, wherein the settings are empirically determined based on one or more operational parameters of the spinning rotor. Operational parameters are stored in a memory bank associated with the control unit. The specific settings for carrying out the cleaning measure for a particular spinning rotor are automatically determined by reference to the operational parameters stored in the memory bank that are applicable to the particular spinning rotor.

Abstract: A cleaning device (1) for cleaning a rotor plate (2) of a spinning rotor (3) comprises a receptacle (6), a cleaning head (4) mounted on the receptacle (6), which can be advanced toward the spinning rotor (3) for cleaning and which includes at least one cleaning element (5, 5a, 5b), and comprising a brake device (11) for decelerating and/or holding the spinning rotor (3) once the cleaning head (4) has been advanced. The cleaning head (4) comprises an at least partially cylindrical receiving area (7) for the spinning rotor (3), which defines an axial direction (AR) and a radial direction (RR) of the cleaning head (4). The brake device (11) contains multiple, in particular two, brake elements (12), which are mounted on the cleaning head (4) in such a way that they are movable from a neutral position into a braking position, and each of the multiple brake elements (12) is movable with the aid of its own drive (13).

Abstract: In a method for cleaning a spinning rotor (4) of a spinning device (1) of an open-end spinning machine, at least one cleaning measure (RM) is carried out on the spinning rotor (4) with the aid of a pneumatic and/or a mechanical cleaning device (7), wherein settings (E), with the aid of which the at least one cleaning measure (RM) is carried out, are predefined by a control unit (24) of the open-end spinning machine. Various parameter (P) are stored in a memory bank (25). Moreover, previously empirically determined settings (E) for carrying out the cleaning measure (RM), which are suitable for the particular parameters (P), and/or rules (R) for determining settings (E) which are suitable for the particular parameters (P) are stored. The settings (E) for carrying out the at least one cleaning measure (RM) are automatically determined by the control unit (24) with the aid of the memory bank (25) depending on presently given parameters (P).
