Abstract: A textile machine component and to a method for providing component information at the textile machine component, in particular at a spindle arrangement for spinning or twisting machines. In order to ensure permanent and reliable provision of component information at a plastic-coated textile machine component, provision is made for the textile machine component to be enclosed at least in sections by a heat-shrinkable plastic enclosure that provides the component information, the enclosure being shrunk onto the textile machine component. In order to provide a plastic-coated textile machine component, in particular a spindle arrangement, with component information that can be acquired reliably, provision is made for a plastic enclosure that provides component information to be shrunk onto at least a section of the textile machine component.

Abstract: A device for checking the construction of an extruder screw having a shaft and screw elements that are to be pushed or have been pushed one after the other onto the shaft in a defined sequence. Each screw element has an element-specific external geometry. A recording device being provided for determining information concerning the sequence of the screw elements that are to be pushed on or have been pushed on and for comparing the information determined with target information, which directly or indirectly describes the target sequence.

Abstract: An extruder having an operative unit composed of a cylinder and at least two screw shafts which are rotatably accommodated therein, a gear unit having at least two output shafts, wherein each output shaft, via a connecting element, is connected in a rotationally fixed manner to one screw shaft, a motor which drives the gear unit and is coupled to the gear unit via a clutch, and a controller installation, wherein each connecting element or each output shaft is assigned a separate measuring installation for determining the applied torque, wherein the measuring installations communicate with the controller installation which, depending on the individual determined torques, controls the clutch which is implemented as a switchable clutch, wherein the controller installation is configured for opening the clutch both when a determined torque exceeds a torque limit value and also when the difference between the two determined torques exceeds a limit value.

Abstract: An extruder having an operative unit having a cylinder and at least one extruder screw which is removably accommodated therein, a motor and a gear unit which is separated from the motor via a clutch and which drives the extruder screw, wherein the extruder screw is releasably connected to the gear unit, and a controller installation which controls the operation of the motor or at least of a further installation which is provided. The operative unit or is assigned to the operative unit, wherein at least one information element which identifies the extruder screw and which, during or after insertion of the extruder screw into the cylinder or connection to the gear unit, is automatically acquirable by a sensor element, is provided on the extruder screw, wherein the controller installation, depending on the acquired information, controls the operation of the motor or of the further installation.
