摘要： A device is described for producing a fiber product by laying down melt-spun fibers onto a laydown belt. A spinning device is associated with a top side of the laydown belt and a suction-extraction device is associated with the bottom side. A vacuum device has a movable suction chamber which interacts with the spinning device in order to lay down the fibers on the laydown belt. To generate a uniform suction flow in every position of the suction chamber, the suction chamber is formed from a stationary bottom box and a movable top box which are coupled to one another in a pressure-tight manner.

摘要： Techniques produce electrostatically charged fibres, and in particular produce an electret fibre construct, where fibres are produced from a plastics and/or natural-origin material, where a polar liquid is atomized using a gaseous pressure medium to produce a treatment aerosol and where the fibres are treated with the treatment aerosol for electrostatic charging, wherein the atomizing is undertaken with a quotient of the volume flow of the polar liquid in litres per second and the positive pressure of the gaseous pressure medium in hectopascals of 0.004 to 0.008.

摘要： Techniques monitor machinery for the production or treatment of synthetic fibers. Such techniques involve constant generation and recording of system messages of machine components and control components. Such techniques further involve continuous storage of the system messages as log data in a log memory. Such techniques further involve readout, preprocessing and analysis of the log data with the aid of algorithms based on statistical procedures and machine learning methods in order to identify frequent sequences of system messages and/or an anomaly.

摘要： Techniques involve texturing a synthetic thread. The thread is pulled off a feed bobbin, which is connected via the thread end thereof to a beginning of a thread of a reserve bobbin by way of a thread knot. In order to monitor the texturing, a thread tension of the thread is measured and analyzed in a measuring point. Additionally, measuring signals of the thread tension are analyzed at the measuring point using a machine learning program, in order to identify the thread knot. To this end, a device has a diagnostic unit, which interacts with the thread tension measuring device in such a way that the measuring signals of the thread tension can be analyzed by way of a machine learning program for identifying a thread knot.

摘要： Techniques are directed to a method and a device for monitoring a yarn tension of a running yarn in a yarn treatment process. To this end, the yarn tension of the yarn is continuously measured and the measurement signals for the yarn tension are compared with a threshold value of an admissible yarn tension. In the event of an inadmissible tolerance deviation of the measurement signals, a short-term signal path of the yarn tension is detected as a fault graph. In order to enable a fault diagnosis, the fault graph of the yarn tension is analyzed using a machine learning program. The fault graph is then allocated to one of the existing fault categories or to a new fault category. A device for this purpose may include a diagnosis unit, which cooperates accordingly with the yarn tension evaluation unit.

摘要： A device for melt-spinning, drawing, and winding a thread group includes a spinning device having a row of spinning nozzles. The threads produced by the spinning nozzles are drawn by means of a godet device with multiple drivable godets. The device is paired with a winding device with multiple winding stations arranged in a row. The row of winding stations is arranged orthogonally to the row of spinning nozzles. The different thread spacings within the spinning device and the godet device are bridged by a thread deflecting device having a first group of thread guides and a second group of thread guides. The thread guides of the first group are arranged next to one another in a horizontal row with a spinning spacing. It is possible to obtain large deflections with a low height. The thread guides of the two groups are made of freely rotatable rollers.

摘要： An apparatus feeds a plurality of threads to rotating godets of a melt spinning machine including a manual injector (e.g., a main manual injector) and a cutting device. In order to be able to selectively feed the threads individually or as a bunch, a transfer device and a second manual injector (e.g., an auxiliary manual injector) are associated with the manual injector.

摘要： Techniques produce a multifilament thread from a polyamide melt. In this case, freshly extruded filaments are cooled and combined to form a thread. In order, in addition to low boil-off shrinkage, to achieve high strength, the thread is taken off at a take-off rate in the range from 3600 m/min to 4600 m/min, preferably from 4000 m/min to 4400 m/min, by a first godet group having unheated guide casings. Subsequently, the thread is fully drawn between the first godet group and a second godet group having heated guide casings. After drawing, the thread is heated to a thread temperature in the range from 140° C. to 200° C. under tension at the guide casings of the second godet group and relaxed. After relaxing, the thread runs in a contact-free manner through at least one free cooling section between the second godet group and a third godet group having unheated guide casings.
