Abstract: A rotary metering head comprises a platform which is rotatable about an axis of rotation and on which a jet valve is arranged that serves for the jetting of fluid materials.

Abstract: A method for executing program components on a control unit includes receiving a first program unit and a second program unit; producing a first proxy definition and a second proxy definition, wherein a proxy definition stipulates access to at least one function and/or a memory area of a program unit, wherein the first proxy definition is associated with the first program unit and the second proxy definition is associated with the second program unit; compiling the first program unit and the second program unit to produce a first program component, a second program component, a first proxy component and a second proxy component; and executing the first program component and the second program component on a control unit, wherein the first program component calls and/or uses at least one function of the second program component by using the first proxy component and the second proxy component.

Abstract: A transport system for spinning bobbins and bobbin tubes comprises a transport path with two essentially vertical sections and an essentially horizontal section connected therebetween. The spinning bobbins and bobbin tubes are transported on pallets whose foot portion comprises an element consisting of magnetizable material. A conveyor belt runs along the transport path at the back side of which belt stationarily arranged permanent magnets are arranged to exert magnetic forces to hold the pallets on the conveyor belt.

Abstract: A device for centering tubes during their processing, for example in a tube cleaning station of a textile machine. In a textile machine provided with several batches of tubes of differing length, diameter and/or material, which cannot be processed together in known cleaning devices, the present device has a rotatably seated holder with at least two differing centering devices adapted for different tubes for selective positionability relative to the tubes to be centered according to sensor devices which detect the differing physical characteristics of the tubes.
