A melt spinning device for producing synthetic threads includes at least a spinneret apparatus, a cooling apparatus, a processing apparatus and a winding apparatus. An automatic operating device is provided for carrying out at least one operator action. The automatic operating device has at least one movable robotic arm, which can be coupled selectively to one of a plurality of exchangeable tools in order to selectively carry out a plurality of operator actions during a start-up and/or during a maintenance interval and/or during thread production. Thus, a high level of flexibility in the automated operation of the melt spinning device is ensured.

Melt spinning device

Techniques are directed to melt spinning, drawing, crimping and winding multiple threads. The threads are spun from a plurality of spinnerets of a spinning device and are drawn as a thread group by a drawing device and are subsequently fed for crimping next to one another to a plurality of texturing units. In order to obtain identical treatment of all threads within the thread group, the threads are guided individually with a plurality of wraps next to one another on a godet unit and, after running off from the godet unit, are guided in a straight thread run parallel next to one another into the texturing units. To this end, adjacent texturing units of the crimping device form a treatment spacing between themselves which is such that, in the case of being guided individually with a plurality of wraps on the godet unit, the threads can be guided in parallel in a straight thread run.

Method and device for melt-spinning, drawing, crimping and winding multiple threads

A spinning, drawing and texturing machine for the production of curled threads includes a spinning unit and multiple machine modules associated with the spinning unit. Each of the machine modules has multiple processing assemblies for drawing and curling one of the threads, and a spooling unit for winding the thread. The machine modules positioned next to one another form a longitudinal side of the machine. The processing assemblies and the spooling unit are arranged among each other at one of the machine modules such that a narrow machine partition (T) in a range of &#x3c;800 mm occurs on the longitudinal side of the machine. The spinning unit has one or more spinnerets and one spinning duct within the machine partition (T) per machine module. The spinnerets are held in rows parallel to the longitudinal side of the machine.

Spinning, drawing and texturing machine

A method and an apparatus for stuffer box crimping a multifilament yarn consisting of one or more fiber bundles, wherein a conveying fluid is introduced into a yarn channel via a plurality of fluid feed channels, with each channel carrying a partial flow. The yarn is pneumatically taken into the yarn channel, and guided, and possibly twisted in the yarn channel by the conveying fluid, and subsequently advanced into a stuffer box chamber. Inside the stuffer box chamber, the yarn is formed into a plug which is compressed and advanced, with the conveying fluid emerging from the stuffer box chamber through side openings. To influence the actions of the conveying fluid on the yarn within the yarn channel, at least one of the fluid feed channels is configured such that the partial flows of the conveying fluid are introduced from the fluid feed channels into the yarn channel under the action of different overpressures.
