Abstract: A device for coupling to a spindle of a machine tool includes a holder for coupling to the spindle of the machine tool, a conveyor element configured to convey a filament and rotatable about an axis of rotation, and a material processing unit. The material processing unit includes a gear which includes a force-receiving element configured to receive a mechanical force from the spindle and rotatable about an axis of rotation which extends substantially orthogonal to the axis of rotation of the conveyor element, and a force-delivery element configured to deliver to the conveyor element the mechanical force transmitted purely mechanically from the force-receiving element, with the force-receiving element being configured separately from the force-delivery element.

Abstract: A production machine includes an electrical positioning drive having a stator and a moveable member displaceable relative to the stator in at least one travel direction. The moveable member is mounted, in relation to the stator, in a contactless manner by a magnetic field in at least one of the supporting directions differing from the travel direction. A sensor device is associated with the positioning drive to shift the moveable member relative to the stator in the supporting direction to be detected. A control device is also associated with the positioning drive, and the shift of the moveable member is detected by the sensor device and can be supplied in the supporting direction. A control signal for a positioning magnet system can be determined by the control device, on the basis of the shift of the moveable member in the supporting direction and a nominal positioning of the moveable member.
