• Texturing machines of this type have a multiplicity of processing points which are arranged next to one another in a machine longitudinal side.
• processing units are arranged in each processing station, each carrying out a process step in order to convey, texturize, stretch, and wind a predetermined synthetic thread into a bobbin as crimped yarn.
• the processing points can be combined into several in a group, so that the large number of processing points is divided into several groups of processing points.
• a central machine control unit is used in the known texturing machine to control the process units in the processing point or in the group of processing points. Here, all data relevant to the control are fed to the machine control unit or entered directly.
• the invention is based on the introduction of a further control hierarchy for controlling the texturing machine, which hierarchy is directly assigned to the processing points or the groups of processing points.
• the processing stations are monitored and controlled independently of one another individually or the group of processing stations independently of adjacent groups of processing stations by a control device.
• the control units are alternately coupled to a mobile control unit for data exchange. The monitoring or control can thus be advantageously shifted close to the action.
• the operating device is activated by an operator is used individually to monitor and control the large number of processing points or groups of processing points.
• Another advantage of the invention is that a texturing machine can be used to produce yarns with different settings in the processing points or in the groups of processing points.
• each of the processing points or each of the group of processing points can be switched off independently of the neighboring groups of processing points for maintenance and troubleshooting. All parameters relevant to the process are stored in the control units.

• the process steps within a processing point are influenced directly via the control device by the operating device coupled to the control device. It is therefore advantageous if all the supplying plants have the same high conveying speed when threading in a processing point. Only after the thread is put on does the difference in the conveying speeds occur, which leads to a stretching of the thread.
