Description

The invention relates to a false twist texturing machine for false twist texturing of a plurality of synthetic threads according to the preamble of claim 1.

It is known that such false twist texturing machines are used to texturize melt-spun multifilament yarns and thus to replicate, as far as possible, the natural fibers in their structure and appearance. For this purpose, the false twist texturing machine has a plurality of processing points, wherein in each processing point at least one thread is treated by several processing units for finishing. In essence, the yarn is drawn in a false twist zone and textured and wound up after texturing into a coil. The process units, such as delivery mechanisms, heaters, cooling devices and false twist texturing, are arranged for this purpose to a job structure on a machine frame, so that sets a predetermined yarn path in the processing stations. Such a false twist texturing machine is known, for example, from WO 01/92615. In the known false twist texturing machine, the plurality of processing stations are divided into several sections. Thus, for example, when using a plurality of 216 processing points, for example, 18 sections of 12 processing points can be formed. To increase the flexibility of the known Falschdralltexturiermaschine the processing sections are independently controllable. In this case, the processing sections are constructed such that in each processing point a job structure is realized in order to be able to optimally texture a yarn with a defined yarn path and predetermined yarn treatments.

New trends in yarn finishing by false twist texturing, such as EP 11 03 641 A1 and EP 11 01 848 A1, show an increased interest in so-called effect yarns that can be produced by a false twist texturing process. This requires additional treatment steps in the yarn path, which can not be realized without problems with the known false twist texturing. The production of effect yarns was previously the air texturing reserved, as known for example from DE 36 23 370 A1. Such texturing machines have few processing points with individually driven and adjustable processing units, so that the processing points can be operated individually. Such high flexibility is not feasible economically in false twist texturing machines due to the large number of processing points. On the contrary, the false twist texturing machines are based on the concept of group drives of process units in order to limit the drive and control effort.

Accordingly, it is an object of the invention to develop the generic Falschdralltexturiermaschine such that a flexible use for the production of textured yarns of various types and designs is possible.

The object of the invention is achieved by a false twist texturing machine having the features of claim 1.

Advantageous developments of the invention are defined by the features and feature combinations of the subclaims.

The invention is based on the proviso that a false twist texturing machine with a plurality of processing stations is used exclusively for the production of a specific yarn. On the contrary, the invention makes it possible for different types of yarn to be produced parallel to one another in a false twist texturing machine.

For this purpose, the false twist texturing machine according to the invention is designed with different peg structures in groups of processing sections. The job structures of the machining sections differ in the number and / or type of process units that are required for the guidance and treatment of one or more threads. As job structure here is meant the arrangement of the process units within a processing section, which are required, for example, for stripping, texturing and stretching the threads associated with the processing section. Thus, in one of the processing sections, an additional treatment of the threads could be achieved by including additional processing units in the job structure of the group of processing stations, such as additional heating devices. However, different treatments of the threads assigned to the machining sections can also be achieved in that the number of process units within the job structure is the same, but the type of process units of at least one group differs from the type of process units of another group. As an example, the processing units provided for the heat treatment could be formed at one of the processing sections by so-called contact heaters, in which the yarn is treated in contact with a heated surface. In contrast, in a neighboring processing section, a heater could be used, in which the threads are heated without contact. In these known as so-called high-temperature heater heaters, the threads are passed over highly heated surfaces without contact. The invention thus has the particular advantage that the plurality of processing stations divided into groups can be used flexibly for processing threads. It can thus be advantageous simultaneously produce different yarns with a machine.

In order to further improve the flexibility of using the false twist texturing machine according to the invention, at least a part of the processing units is within the job structures of the processing sections Process modules held, which are removably attached to a module frame designed as a part of the machine frame. This makes it possible to modify the job structure of the processing section in a simple manner.

In this case, it is particularly advantageous if, according to an advantageous development of the false twist texturing machine according to the invention, the module frame can optionally be equipped with one or more process modules per processing section. The process modules carry at least one group of processing units, each of which carries out a process step in the processing stations of the processing section. Thus, by selecting and assembling several process modules, it is advantageously possible to produce yarn types which are formed from a plurality of threads. Thus, a flexible job set-up is provided to integrate additional process aggregates needed over a standard process to produce special effect yarns.

According to a particularly advantageous embodiment of the invention, the process modules each have an electrical distributor, which is connected to the process units of the process module and which has inputs and outputs for the electrical coupling of the process units. Thus, on the one hand, the cabling effort to supply individual process units within the processing section is significantly reduced and on the other hand greatly simplifies the replacement of individual process modules by simply loosening plug connections between supply lines and the electrical distributor.

The drivable process units, which are essentially formed by delivery mechanisms, are preferably driven by individual drives on the process modules, wherein the individual drives are supplied and controlled via the electrical distributor. All individual drives of the process units on the process module are controlled by a group converter. It is, however possible that each individual drive directly to the process module is assigned in each case one inverter.

It has been found that the different treatments for the production of different types of yarn take place essentially in the inlet area of the process. On the basis of this finding, according to an advantageous further development of the false twist texturing machine according to the invention, the module frame is arranged in the inlet area of the machine and the group of processing units carrying a thread from a supply spool is carried within the place structures of the processing sections. Such process units are formed by deduction delivery plants.

To further increase the flexibility, in particular in the inlet region of the machine, the process modules are advantageously designed with additional receiving devices per processing point, by means of which optional additional processing units can be integrated within the processing point on the process module.

As additional processing units, additional delivery units, drafting pins, Tangeleinrichtungen and / or bobbin original can optionally be provided per processing point. For example, a second thread can be fed to the process module by the bobbin original in order to produce a composite thread in the processing station. By a draw pin or a Tangeleinrichtung a withdrawn from the deduction delivery thread could be additionally treated before the false twist texturing.

In order to enable the operability of the process units within the false twist texturing machine in a simple manner, according to an advantageous development of the invention, an operating passage is formed between the module frame and a process frame. The process frame carries at least part of the processing units such as False twist text courier and delivery works. The process units can be operated from the operating gear on both sides, preferably by an operator.

Due to the developments of the invention according to claim 9 and claim 10 ensures that the guided in the Falschdralltexturiermaschinen threads do not intersect. Due to the little deflected yarn path within a processing point, regardless of the type of yarn, the yarn can be guided in a very stable and short yarn path. The arrangement of the heater and the cooling device above the operating gear also has the advantage that a sufficient length for heat treatment and cooling of the false twisting thread can be realized. Due to the assembled to a frame part process and Aufwickelgestelle also a compact construction of the false twist texturing machine is achieved.

In order to change the setting of the process parameters such as take-off speeds, drawing ratios or heater settings in a simple manner, the processing units forming the job structure of one of the processing sections are controlled and monitored independently of the processing units of the adjacent processing section. For this purpose, each processing section is preferably assigned a field control unit, by means of which all process parameters within the group can be defined and changed.

The invention will be described in more detail below with reference to an embodiment with reference to the accompanying drawings.

In Fig. 1 is a schematic plan view of an embodiment of the invention Falschdralltexturiermaschine is shown. The false twist texturing machine has a machine frame 4. The machine frame 4 is formed by a module frame 4.1, a process frame 4.2 and a Aufwickelgestell 4.3, which are firmly connected. At a distance to the module frame 4.1, a separate gate frame 7 is arranged.

In the machine frame 4, a plurality of processing points 1.1, 1.2, 1.3, etc. are arranged parallel to each other in the longitudinal direction. Usually, in a false twist texturing machine, over 200 processing points are preferably provided 218 processing points. In the exemplary embodiment in FIG. 1, by way of example only the first three processing stations are identified by the reference symbols 1.1, 1.2 and 1.3. In each of the processing stations 1 at least one thread is processed in each case. The plurality of processing stations 1 are divided into several processing sections 2. In the embodiment shown in FIG. 1, in each case 12 adjacent processing points 1.1, 1.2, 1.3, etc. form a processing section 2. In FIG. 1, the first two are exemplified for this purpose Machining sections 2.1 and 2.2 as well as partially the third machining section 2.3 shown Each machining section 2.1, 2.2, 2.3, etc. contain several processing units, which are held in a job structure in your machine frame 4, to deduct the threads of the processing section associated threads in parallel from original spools to texturize to stretch and wind up coils.

In Fig. 1, only a portion of the provided in the processing section or in the individual processing stations process units with the reference numerals 10, 11, 12, 13, 16 and 18 are shown schematically. By the reference numeral 10, the group of deduction delivery plants is marked, each processing point is assigned in each case a deduction delivery, to deduct a thread 38 from a supply spool 8. The supply spool 8 is received in the gate frame 7. For stretching and texturing, the thread 38 is guided in a processing station, for example, the processing station 1.1 in a false twist zone, which is formed by the Primärheizeinrichtung 11, the cooling device 12 and the Falschdralltextkurieraggregat 13. Thereafter, the thread 38 is subjected to a post heat treatment in each of the processing points, which is carried out by the secondary heater 16. At the end of processing, the thread 38 is wound to a bobbin 21 held on a bobbin holder 46 in the winder 18. The winders 18 occupy a width of 3 processing points. Therefore, each of three rewinders - will be discussed later - arranged in a column one above the other in the Aufwickelgestell 4.3.

To control the process units, which are only partially represented in FIG. 1 by reference numbers 10, 11, 13, 16 and 18, a field control unit 42 is assigned to each processing section. Thus, the processing section 2.1, the field control unit 42.1 and the processing section 2.2, the field control unit 42.2 assigned. The field control units 42.1 and 42.2 as well as the field control units (not shown here) of the subsequent processing sections of the false twist texturing machine are coupled to a machine control 43. The process units of a processing section can thus be controlled and monitored independently of the processing units of the adjacent processing section.

The processing sections 2 of the false twist texturing machine each have a specific job structure for processing the threads assigned to the processing section. Hereinafter, the job structure of the machining section 2.1 will be described with reference to a cross-sectional view of a machining point of this machining section of FIG. 2 and the job structure of the machining section 2.2 with reference to the cross-sectional view of one of the machining points of this machining section of FIG.

2, a processing station 1 of the processing section 2.1 is shown schematically in a cross-sectional view. The processing units arranged in the machine frame 4 to a job structure are in the processing section 2.1 by a deduction delivery 10, a primary heater 11, a cooling device 12, a false twist text messenger unit 13, a drafting device 14, a swirling device 40, a set delivery 15, a secondary heater 16, a supply delivery 17 and a winding device 18 is formed, wherein the process units are arranged to form a yarn path in a row.

In the processing section 2.1, each processing point has a deduction delivery unit 10. The deduction delivery plants 10 of the processing section 2.1 are attached to a process module 3.1. The process module 3.1 is attached to the module frame 4.1. The design of the process module and the nature of the module frame 4.1 will be explained in more detail below.

Each of the deduction suppliers is assigned to one of the original coil 8, which are arranged in the gate frame 7. In the gate frame 7, each of the feed bobbins 8 is assigned a spare spool 44, wherein the thread end of the spool 8 is knotted to the thread spine of the reserve spool 44. From the original spool 8, the thread 38 is withdrawn via a head thread guide 45 and the thread guides 9.1 and 9.2 through the deduction delivery unit 10.

Based on the yarn path of the thread 38 in the processing station of the processing section 2.1, the other process units are described in the job description below. In the thread running direction behind the deduction delivery unit 10 is the elongated primary heater 11, through which the thread 38 is running and is heated to a certain temperature. The primary heater 11 could be designed as a high-temperature heater, in which the Heizoberflächentemperatur is above 300 ° C. The thread 38 in this case would preferably be heated without contact. The primary heater 11 is seated in this embodiment, two parallel tracks, so that the threads 38 two adjacent processing points are performed simultaneously by the primary heater 11.

In the thread running direction behind the primary heater 11, the cooling device 12 is provided. The primary heater 11 and the cooling device 12 are arranged in this embodiment in a plane behind the other above the module frame 4.1 and the process frame 4.2, wherein between the module frame 4.1 and the process frame 4.2 an operating gear 5 is formed. In the entrance area of the primary heater 11 is a yarn guide 9.3, which is preferably designed as a deflection roller, arranged so that the thread 38 is guided by the module frame 4.1 in a V-shaped yarn path to the process frame 4.2. However, the job structure could also be designed such that the primary heater 11 and the cooling device 12 are arranged in two roof-shaped mutually lying planes.

On the module frame 4.1 opposite side of the process frame 4.2 is arranged. The process frame 4.2 carries in the thread running direction in succession the Falschdralltextkurieraggregat 13, the drafting device 14, the swirling device 40 and the set-delivery 15. In this case, the thread 38 from the output of the cooling device 12, which is preferably formed by a cooling rail, to the false twist text tracing unit 13th guided. The false twist unit 13, which may be formed for example by a plurality of overlapping friction discs, is driven by a false twist drive 26. As a false twist drive 26, an electric motor is preferably used, which is also attached to the process rack.

By the draw delivery 14 of the thread 38 is subtracted from the false twist zone, which forms between the Falschdralltextkurieraggregat 13 and the deduction delivery unit 10. The drafting delivery 14 and the delivery delivery 10 are driven to draw the yarn 38 in the false twist zone at a differential speed.

Below the stretch delivery unit 14, the thread 38 passes through the swirling device 40. The thread 38 is guided into the secondary heating device 16 by the set delivery mechanism 15. The secondary heater 16 is for this purpose on the underside of the process frame 4.2 and the Aufwickelgestells 4.3, which are both joined together to form a frame part. The secondary heater 16 forms the thread transition from the process frame 4.2 to the winding frame 4.3. As a result, a very compact design is realized.

On the underside of the Aufwickelgestells 4.3 the feed delivery plant 17 is arranged, which immediately deducts the thread 38 from the secondary heater 16 and after deflecting the thread 38 leads to the winding device 18. The set delivery mechanism 15 and the feed delivery mechanism 17 are driven at a differential speed such that shrinkage treatment of the thread 38 within the secondary heater 16 is possible. The Secondary heater 16 could in this case be formed by a diphyl-heated contact heater.

The winding device 18- is schematically characterized in this embodiment by a traverse 20, a drive roller 19, a coil holder 46 and a coil 21. The winding device 18 also includes a sleeve magazine 22 to perform an automatic bobbin change. The auxiliary equipment required for replacing the full bobbins are not shown here. In the take-up frame 4.3, a total of three take-up devices 18 of adjacent processing points are arranged one above the other in terms of floor space. The winders of the processing section form a machine longitudinal side, over the length of which a Doffgang 6 extends. From the Doffgang 6 let out the full bobbins transport.

The delivery mechanisms 10, 14, 15 and 17 in the job structure of the processing section 2.1 are identical in their construction, so that the example of the deduction delivery 10 this will be explained below. Each delivery mechanism is formed by a godet 23 and an overflow roller 24 associated with the godet 23. The godet 23 is driven by a single drive 25. The individual drive 25 is preferably formed by an electric motor. The overflow roller 24 is freely rotatably mounted, wherein the thread 38 is guided with several wraps on the godet 23 and the overflow roller 24.

The illustrated in Fig. 2 job structure of the processing section 2.1 has in the processing stations on the process units to draw a submitted thread 38 in a basic process and to texture. For this purpose, the thread 38 is withdrawn by the deduction delivery unit 10 of the original spool 8, guided in the false twist zone. By Falschdralltextkurieraggregat 13 at the end of the false twist zone a false twist is generated in the thread 38, which runs back to the primary heater 11. Within the primary heater 11 and the cooling device 12 is a fixing of the conditional by the texturing Crimping in the multifilament yarn 38. The yarn 38 is withdrawn from the false twist zone by the draw delivery unit 14 and drawn. For this purpose, the stretch delivery unit 14 is driven at a higher speed than the deduction delivery unit 10. After the texturing of the thread 38, a further treatment by turbulence and heating takes place. Subsequently, the thread 38 is wound into a coil 21.

To operate the machine, an operating gear 5 is formed between the module frame 4.1 and the process frame 4.2. Thus, the process units on the module frame 4.1 and the process units on the process frame 4.2 can advantageously be operated by an operator from the operation gear 5. For receiving and removing the coils 21, a Doffgang 6 is provided on the longitudinal side of the Aufwickelgestells 4.3.

For a more detailed explanation of the position structure of the processing point 2.1 in the inlet region of the machine some views of a section of the module frame 4.1 of the processing section 2.1 are shown in Fig. 3. Here, in FIG. 3.1, a front view of the process module 3.1 and in FIG. 3.2 a rear view of the process module 3.1 are shown. The following description applies to both figures, insofar as no explicit reference is made to one of the figures.

The process module 3.1 is mounted replaceably on the module frame 4.1 via a plurality of fastening elements 27. The module frame 4.1 in this case has several module slots 47. Overall, three module slots 47.1, 47.2 and 47.3 are formed on the module frame 4.1. In the module space 47.1, the process module 3.1 is attached. The process module 3.1 of the processing section 2.1 carries the group of deduction delivery plants 10. In Fig. 3.1 and 3.2, three adjacent deduction delivery plants 10.1, 10.2 and 10.3 are shown. Each of the delivery units 10.1, 10.2 and 10.3 is driven by a single drive 25.1, 25.2 and 25.3. Thus drives the single drive 25.1 the deduction delivery 10.1 and the single drive 25.2 the deduction delivery 10.2.

Each of the deduction delivery 10.1, 10.2, 10.3, etc. of the processing points pulls a thread 38 from a supply spool on the yarn guide 9.1. At the process module 3.1, all individual drives 25 of the deduction delivery units 10 are connected to an electrical distributor 48. The electrical distributor 48 has a plurality of plug connections 49. Via the plug connections 49 and the electrical distributor 48, the electrical connection of the individual drives 25 of the delivery units 10 takes place. The individual drives 25 are preferably controlled via a group converter. The group converter could either be part of the electrical distributor 48 or be arranged externally in an electronic assembly assigned to the machining sections 2.1.

The job structure of the adjacent machining section 2.2 of the embodiment is shown by a cross section of a machining point of the machining section 2.2 in FIG. The job structure of the processing station 2.2 is substantially identical to the job structure of the processing station 2.1, so that reference is made at this point to the previous description and then only the differences in job structure will be described. Because of the overview, the components of the same function have been identified with identical reference numerals.

In the inlet region of the processing section 2.2, two process modules 3.1 and 3.2 are arranged one below the other on the module frame 4.1. The process module 3.1 carries the deduction delivery units 10 of the processing points of the processing section 2.2. The construction of the process module 3.1 is identical to the process module arranged in the adjacent processing section 2.1. In that regard, reference is made to the preceding description. At the second process module 3.2, a delivery mechanism 29 and a delivery point 36 are arranged per processing point. In the presentation point 36 on the process module 3.2, a supply reel 37 is held in each processing station, on which an additional thread 39 is presented. The additional thread 39 is subtracted by the delivery mechanism 29 to the process module 3.2 and above the operating 5 arranged deflection rollers 41.1 and 41.2 supplied to the stretch delivery 14. In the swirling device 40 below the stretch delivery unit 14, the additional thread and the thread 38 are brought together to form a composite thread.

The job structure of the processing section 2.2 thus contains additional processing units, - to produce in each case a composite thread in the associated processing points of the processing section 2.2. As an additional thread z. B. an elastane thread the crimped thread are attached. For this purpose, the thread 38 is withdrawn in each of the processing points of the machining section 2.2 and fed to the false twist zone by the deduction mechanism 10. The additional thread 39 is withdrawn by the delivery mechanism 29 from the original spool 37 via a yarn guide 35 attached to the process module 3.2 in each of the processing points. For this purpose, the supply spool 37 is arranged at the initial position 36 on the process module 3.2. The additional thread 39 is passed over deflection rollers 41.1 and 41.2 at the false twist zone directly to the stretch delivery unit 14. After texturing and stretching of the thread 38 of the thread 38 and the additional thread 39 is connected in the swirling device 40. The resulting composite thread is wound up after a heat treatment in the secondary heater 16 to form a coil 21.

The inlet area of the processing section 2.2 is shown schematically in different views for a more detailed explanation of the process modules 3.1 and 3.2 in Figures 5.1 and 5.2. Fig. 5.1 shows a detail in a front view of the operation gear 5 out and Fig. 5.2 shows a section of the back of the module frame 4.1. The module frame 4.1 is occupied in the processing section 2.2 in the module slots 47.1 and 47.2, each with the process module 3.1 and 3.2. The process module 3.1 in the processing section 2.2 is identical to the process module 2.1 in the processing section 2.1. In that regard, reference is made to the preceding description.

The process module 3.2 carries the group of delivery mechanisms 29 of the processing section 2.2. In Fig. 5.1 the first three delivery mechanisms 29.1, 29.2, 29.3 of the groups are shown. Each of the delivery mechanisms 29 is formed by a driven godet 31 and an overrun roller 30. The godet 31 is driven by a single drive 33, wherein the individual drives 33.1, 33.2 and 33.3 of the first three delivery mechanisms 29.1, 29.3 and 29.3 are shown. For the electrical supply of the individual drives 33, the process module 3.2 also has an electrical distributor 48, which is coupled to the individual drives 33 of the delivery mechanisms 29. The electrical distributor 48 is connected via the plug connections 49 to an external power supply and control device.

At the process module 3.2, a feed point 36, which is provided for receiving a feed bobbin 37, is provided below the delivery mechanisms 29 for each processing point of the processing section 2.2. Between the transfer point 36 and the delivery mechanism 29, a thread guide 35 is arranged on the process module 3.2 per processing point. By means of the process modules 3.1 and 3.2, two threads 38 and 39 can thus be deducted per processing point and processed by subsequent processing units - within the processing section 2.2 to form a composite thread. The control of the processing units of the processing section 2.2 is determined by the associated field control unit 42.2.

The following processing sections of the embodiment may each have a job structure corresponding to the job structure of the machining section 2.1 of FIG. 2 or the job structure of the machining section 2.2 of FIG. However, it is also possible that at least one of the processing stations of the embodiment has a third different job structure for producing a further yarn type. Typically, however, such false twist texturing machines are operated with few different spot structures in the processing sections.

In the embodiment described above, the location structures of the processing sections are substantially changed by additional process units, which are arranged substantially in the inlet region of the machine. In principle, all processing units arranged within the job structure are suitable for generating changes in the job structure. Thus, for example, the job structure of the processing section 2.1 of the embodiment could be changed by the fact that the secondary heater 16 is not operated, so that a false twist-textured thread is wound into a coil without a post-heat treatment. It is also possible to use a primary heater 11 in a processing section, which is designed as a non-contact heater and to use a contact keyer as a primary heater 11 in an adjacent processing section. The invention is not limited to the fact that the process module are arranged exclusively in a module frame placed in the inlet region. Thus, in particular, the process rack is suitable for accommodating one or more process modules with one or more groups of processing units as a module rack. In particular, in the aforementioned embodiment, a process module, which is constructed correspondingly in the process module 3.1, could be arranged between the swirling device 40 and the draft delivery device 14. This would precede an additional delivery mechanism of the swirling device 40, so that a separate adjustment of the tension for swirling the thread or threads is possible.

FIG. 6 shows further exemplary embodiments of process modules 3, such as could be used, for example, in one of the processing sections. The embodiment of the process module 3 shown in FIG. 3.1 is particularly suitable for producing a composite thread. For this purpose, the delivery unit 10 and the delivery mechanism 29 are mounted together on the process module 3. FIG. 6.1 shows the structure of the process module 3 of a processing station. The delivery mechanism 29 is at the process module 3, the reference point 36 and the Thread guide 35 assigned. In the template point 36, a document spool 37 is held. The deduction delivery unit 10 and the delivery mechanism 29 on the process module 3 are preferably arranged in different thread running planes to guide two parallel threads without additional deflection in the processing site.

FIG. 6.2 shows a further exemplary embodiment of a process module 3, in which the process module 3 has the trigger delivery unit and a further delivery mechanism 29. Both delivery mechanisms are each formed by an overflow roller and a godet. Between the delivery mechanisms 10 and 29, a swirling device 40 is held on the process module. The swirling device 40 is connected to a compressed air source (not shown here), so that the thread 38 routed through a thread channel is swirled by a stream of compressed air. This pre-treatment of the thread 38 preceding the false twist crimp leads to an improvement in the bulkiness of the thread in the crimped state.

FIG. 7 shows a further exemplary embodiment of a process module 3 schematically in a section for a processing station. The process module 3 is shown here in a first configuration in FIG. 7.1 and in a second configuration in FIG. 7.2. In the embodiment of the process module 3 shown in FIG. 7.1, the deduction delivery unit 10 already described above is arranged. The deduction delivery 10 are associated with a plurality of receiving device 28, through which the inclusion of additional process units is possible. In the embodiment shown in FIG. 7.1, the process module 3 is described without additional processing units held in the receiving devices 28.

In FIG. 7.2, the receiving devices of the process module 3 are occupied by an additional delivery mechanism 29 and a draw pin 34. In this embodiment, in the processing section in each processing station pulled through the deduction delivery 10 a thread 38 from a document coil. From the deduction delivery unit 10, the thread 38 is guided into a first draw zone, which extends between the deduction delivery unit 10 and the delivery mechanism 29. Within the draw zone, a heated draw pin 34 is arranged. The draw pin 34 could in this case be heated to a surface temperature in the range from 80.degree. C. to 160.degree. The draw pin 34 is looped by the thread 38 and withdrawn from the delivery mechanism 29. In the event that the thread should only perform a partial looping on the draw pin 34, the draw pin 34 could be assigned to a thread guide on the process module 3, which would be variable in its position to set a certain angle of wrap on the draw pin 34. From the delivery mechanism 29, the thus pre-stretched thread 38 is guided into the false twist texturing zone. The further yarn path could correspond to the job structure of the processing section 2.1 of the embodiment described. The electrical supply and control of the delivery mechanisms 10 and 29 and the drafting pin 34 via the previously described electrical distributor (not shown here).

The Faslchdralltexturiermaschine invention is thus extremely flexible in order to produce different types of yarn simultaneously.
