Description

False twist texturing machine

technical field

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

Background technique

It is known to use such false twist texturing machines for texturing melt-spun multifilament filaments and thereby making the filaments look like natural fibers in their structure and appearance. For this purpose, the false twist texturing machine has a plurality of processing stations, wherein at each processing station at least one filament is processed by a plurality of finishing work units. Here, the filaments are stretched and texturized essentially in a false twist zone and are wound up into a package after texturization. For this purpose, the working units, such as output rolls, heating devices, cooling devices and false twist texturing units, are arranged on a frame to form a positional layout, whereby a given yarn flow is adjusted at the processing position. Such a false twist texturing machine is known for example from WO 01/92615. In known false twist texturing machines, a number of processing positions are divided into processing zones. Thus, for example, when 216 processing positions are used, for example, 18 processing areas each with 12 processing positions can be formed. In order to increase flexibility, in known false twist texturing machines, the processing zones can be controlled independently of each other. In this case, the processing area is designed in such a way that at each processing point a positional layout is realized in order to be able to optimally deform the filaments with a defined filament flow and a given filament treatment.

For example by EP 11 03 641 A1 and EP 11 01 848 A1 the new development trend of thread finishing by false twist texturing is known, and the so-called fancy silk threads that can be processed by a false twist texturing process show obvious benefits. The additional processing steps in the yarn process required for such a false twist texturing process cannot easily be implemented without problems by known false twist texturing machines. It is known, for example, from DE 36 23 370 A1 that hitherto the processing of fancy yarns has been pretreated by means of air texturing machines. This texturing machine has several processing stations with independently driven and adjusted working groups, so that the processing stations can be driven individually. This high degree of flexibility cannot be realized economically in false twist texturing machines due to the many processing positions. In contrast, the false twist texturing machine is based on a group drive concept of the working group in order to keep the drive and control costs within limits.

Contents of the invention

It is therefore the object of the present invention to design such a false twist texturing machine in such a way that it can be used flexibly for the production of different types and configurations of texturized yarns.

This object is achieved according to the invention by a false twist texturing machine with the features of claim 1 .

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

The present invention gets rid of a false twist texturing machine with many processing positions only for the production of a certain yarn. On the contrary, the present invention enables parallel side-by-side production of different yarn forms in one false twist texturing machine. For this purpose, the false twist texturing machine according to the invention consists of different positional arrangements with groups of processing zones. The positional arrangement of the processing zones differs in the number and/or type of work units that are required for guiding and handling the one or more filaments. The positional arrangement here means the arrangement of working groups within a processing area which are required, for example, for drawing, crimping and stretching the filaments assigned to this processing area. In one of the processing zones, therefore, additional processing of the filaments can be achieved by including additional work groups, for example additional heating devices, in the location layout of the processing station group. However, the different treatment of the yarns assigned to the processing area can also be realized in such a way that the number of working groups within the location arrangement is the same, but the type of working group of at least one group differs from the type of working group of another group. For example, a work unit for heat treatment can be formed for a processing zone by so-called contact heaters, in which the filaments are in contact with a heated surface. Instead, a heating device can be used for an adjacent processing zone, in which the filaments are heated without contact. In such known heating devices, known as so-called high-temperature heaters, the filaments are passed through the high-temperature heated surface without contact. The invention therefore has the particular advantage that a plurality of processing stations distributed in groups can be flexibly used for processing the filaments. In this way, different threads can also advantageously be processed simultaneously with one device.

In order to further improve the flexibility of use of the false twist texturing machine according to the present invention, at least a part of the working group is kept inside the position layout of the processing area by the working modules, which are replaceably fixed on an equipment frame formed by a modular frame partly on. The positional layout of the working area can thus be changed in a simple manner.

It is particularly advantageous here that, 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 working modules per processing zone. The work module has at least one group of work groups which each carry out a work step in a processing position of the processing area. A plurality of working modules can thus be advantageously processed by selection and combination of a filament form consisting of a plurality of filaments. This results in a flexible layout for the combination of additional working units required for standard work in order to produce special fancy yarns.

According to a particularly advantageous refinement of the invention, the working modules each have an electrical distributor, which is connected to the working groups of the working modules and which has inputs and outputs for electrical coupling to the working groups. This, on the one hand, significantly reduces the cable laying costs for feeding the individual operating units within the processing area, and on the other hand, significantly simplifies the individual operating modules by easily releasing the plug-in connections between the supply lines and the electrical distributors. replacement.

The drivable working group, which essentially consists of output rollers, is preferably driven on the working module by means of individual drives, wherein the individual drives are fed and controlled via electrical distributors. Here, all individual drives of the working group are controlled on the working module via a combined frequency converter. However, it is also possible to assign a separate frequency converter directly to the operating module for each individual drive.

It has been found that the different treatments for processing the different filament types take place mainly in the entry area of the job. Based on this recognition, according to an advantageous development of the false twist texturing machine according to the invention, the modular frame is arranged in the entry area of the device and has a working group inside the position layout of the processing area, which feeds the package from the Pull out the filament. This work unit consists of pulling rollers.

In order to further increase the flexibility, especially in the area of the device access, the working module is advantageously designed for each processing location with additional mounting devices, by means of which additional working groups can be selectively combined within the processing location to the working module.

As an additional working unit, each processing station can also optionally be equipped with further delivery rollers, drafting pins, entanglement devices (Tangeleinrichtung) and/or wire feeding stations (Spulenvorlage). Thus, for example via the bobbin magazine, the second filament on the working module can be transported to the working area in order to be processed into a composite filament at the processing station. The filament drawn from the drawing roll can be additionally processed before the false twist texturing by means of a drafting pin or an entangling device.

In order to enable the operability of the working group within the false twist texturing machine in a simple manner, according to an advantageous development of the invention, an operating channel is formed between the module frame and the working frame. Here, the work frame is at least a part of a work unit such as a false twist texturing unit and output rolls. The working group can be operated from the operating channel to both sides, preferably by an operator.

The developments of the invention according to claims 9 and 10 ensure that the filaments guided in the false twist texturing machine do not cross. Due to the slightly deflected filament path within the processing position, the filament is guided with a very stable and short thread path, regardless of the filament type. Furthermore, the arrangement of the heating device and the cooling device above the operating channel has the advantage that a sufficient length can be achieved for heat treatment and cooling of the false twisted filaments. Furthermore, a compact structure of the false twist texturing machine can be realized by combining the working and winding frames into one frame part.

In order to be able to change the setting of process parameters such as drawing speed, drawing ratio or heating regulation in a simple manner, the operating frames constituting the position layout of one of the processing areas are independent of the operating frames of the adjacent processing areas. Control and monitor. For this purpose, each processing zone is preferably assigned a zone control unit, by means of which all process parameters within the group can be determined and changed.

Detailed ways

FIG. 1 schematically shows a plan view of an exemplary embodiment of a false twist texturing machine according to the invention. The false twist texturing machine has an equipment frame 4 . The equipment frame 4 here consists of a module frame 4.1, a work frame 4.2 and a winding frame 4.3, which are rigidly connected to each other. A separate creel 7 is arranged at a distance from the module rack 4.1.

A plurality of processing stations 1 . 1 , 1 . 2 , 1 . 3 etc. are arranged parallel to one another in the longitudinal direction in the equipment rack 4 . Generally more than 200, preferably 218 processing positions are arranged in a false twist texturing machine. In the exemplary embodiment in FIG. 1 , only the first three machining positions are indicated by way of example with the reference numerals 1.1 , 1.2 and 1.3 . At least one filament is processed at each processing station 1 . A plurality of processing locations 1 is divided into a plurality of processing areas 2 . In the exemplary embodiment shown in FIG. 1 , every 12 adjacent processing locations 1 . 1 , 1 . 2 , 1 . 3 , etc. form a processing area 2 . For this purpose, the first two processing areas 2.1 and 2.2 and the third processing area 2.3 are partially shown in FIG. 1 by way of example. Each processing area 2.1, 2.2, 2.3, etc. includes a plurality of working units, which are kept in a position layout in the equipment rack 4, thereby pulling, crimping and stretching from the feeding bobbins in parallel and assigned to the processing area The filaments at each processing position are wound into bobbins.

In FIG. 1 , only a part of the working group arranged in the processing area or in the respective processing positions is shown schematically with the reference numerals 10 , 11 , 12 , 13 , 16 and 18 . Reference numeral 10 denotes a set of pulling rollers, one pulling roller being assigned to each processing station in order to pull a thread 38 from a feed bobbin 8 . The feed bobbin 8 is housed in the creel 7 . For stretching and texturing, the filament 38 in a processing station, for example processing station 1.1, is fed to a false twisting zone, which consists of a primary heating device 11, a cooling device 12 and a false twisting unit 13. The filaments 38 are then subjected to an afterheat treatment by the secondary heating device 16 in each processing station. At the end of the process, the filament 38 is wound up in a winding device 18 onto a bobbin 21 held on a bobbin holder 46 . The winding device 18 occupies the width of 3 processing positions. Three winding devices, which will be described below, are therefore each arranged one above the other in the winding frame 4.3 to form a row.

In order to control the working groups, which are only partially indicated by reference numerals 10 , 11 , 13 , 16 and 18 in FIG. 1 , an area control unit 42 is assigned to each processing area. Therefore, an area control unit 42.1 is assigned to the processing area 2.1 and an area control unit 42.2 is assigned to the processing area 2.2. The zone control units 42 . 1 and 42 . 2 as well as the zone control units of the subsequent processing zone of the false twist texturing machine (not shown here) are connected to the plant controller 43 . It is thus possible to control and monitor the working groups of one processing area independently of the working groups of adjacent processing areas.

The processing zones 2 of the false twist texturing machines each have a defined positional layout for processing the filaments assigned to this processing zone. The position layout of this processing area 2.1 is described below by means of a cross-sectional view of a processing position in the processing area of Figure 2, and the position layout of the processing area 2.2 is described by means of a cross-sectional view of a processing position in the processing area of Figure 4 .

A processing location 1 of the processing area 2 . 1 is schematically shown in FIG. 2 in a cross-sectional view. In the equipment frame 4, a work group is arranged in a position layout. In the processing area 2.1, there is a pulling roll 10, a primary heating device 11, a cooling device 12, a false twist texturing unit 13, and a stretching roll 14. , an eddy current deformation device 40, a calibrating roller 15, a secondary heating device 16, a conveying roller 17 and a winding device 18, wherein the operating units are arranged sequentially into a filament process.

In the processing zone 2.1 there is one pulling roller 10 per processing location. The pulling rolls 10 of the processing area 2.1 are arranged on a working module 3.1. The operating module 3.1 is fixed on the module rack 4.1. The structure of the working module and the structure of the module rack 4.1 will be described in detail below.

A feed bobbin 8 , which is arranged in the creel 7 , is assigned to each pulling roller. A spare bobbin 44 is assigned to each feed bobbin 8 in the creel 7 , wherein the yarn end of the feed bobbin 8 is joined to the yarn start of the spare bobbin 44 . From the feed bobbin 8, the filaments 38 are drawn off via an end yarn guide 45 and over the yarn guides 9.1 and 9.2 over the take-off roller 10.

A further working group in the station arrangement is described below with the aid of the thread flow of the thread 38 in the processing position of the processing area 2.1. An elongated primary heating device 11 is located downstream of the drawing roll 10 in the filament flow direction, through which the filament 38 runs and is heated to a certain temperature. In this case, the primary heating device 11 can be formed by a high-temperature heater, wherein the temperature of the heating surface exceeds 300° C. In this case, the filaments 38 are preferably heated without contact. In this exemplary embodiment, the primary heating device 11 has two parallel travel paths, so that the filaments 38 of two processing stations next to each other run through the primary heating device 11 at the same time.

A cooling device 12 is arranged downstream of the primary heating device 11 in the direction of filament flow. The primary heating device 11 and the cooling device 12 are arranged in this embodiment one after the other in a plane above the module frame 4.1 and the working frame 4.2, wherein between the module frame 4.1 and the working frame 4.2 a Operate channel 5. A yarn guide 9.3 is arranged in the inlet region of the primary heating device 11, which preferably consists of a deflection roller, so that the yarn 38 is guided from the module frame 4.1 to the working frame 4.2 in a V-shaped yarn flow. However, the layout can also be designed such that the primary heating device 11 and the cooling device 12 are arranged in two roof-shaped planes relative to each other.

The working frame 4.2 is arranged on the side opposite to the module frame 4.1. The working frame 4.2 supports the false twist texturing unit 13, the drawing roll 14, the eddy current texturing device 40 and the calibrating roll 15 successively along the filament flow direction. The filaments 38 are conveyed from the outlet of the cooling device 12 , preferably formed by a cooling rail, to the false twist texturing unit 13 . For example, the false twist assembly 13 , which consists of a plurality of superimposed friction plates, can be driven via a false twist drive 26 . An electric motor is preferably used as the false twist drive 26, which is likewise mounted on the work frame.

The filaments 38 are drawn via the draw roll 14 out of the false twist zone formed between the false twist texturing unit 13 and the drawing roll 10 . The drawing roll 14 and the drawing roll 10 are driven at a differential speed in the false twist zone in order to draw the filament 38 .

Below the draw roll 14 the filament 38 passes through an eddy current texturing device 40 . The filament 38 is fed to the secondary heating device 16 by means of the calibrating roller 15 . The secondary heating device 16 is arranged here below the working frame 4.2 and the winding frame 4.3, which are joined together to form a frame part. The secondary heating device 16 forms the yarn transition from the working frame 4.2 to the winding frame 4.3. A very compact design is thereby achieved.

Arranged on the underside of the winding frame 4 . 3 are delivery rollers 17 , which pull the filament 38 directly out of the secondary heating device 16 and convey the filament 38 to the winding device 18 after deflection. The calibrating roller 15 and the delivery roller 17 are driven at a differential speed so that a shrinking process of the filament 38 can take place within the secondary heating device 16 . The secondary heating device 16 is formed here by a Diphyl heating contact heater.

The winding device 18 is represented simplified in this embodiment by a reciprocating device 20 , a drive roller 19 , a bobbin holder 46 and a mandrel 21 . Furthermore, the winding device 18 includes a bobbin magazine 22 for automatic bobbin changing. The auxiliary devices required for changing full bobbins are not shown in detail here. A total of three winding devices 18 of adjacent processing stations are stacked in the winding frame 4.3 in a stacked manner. The winding device of the processing zone forms a longitudinal edge of the device, along whose length a doffer channel 6 extends. Full bobbins can be transported out of the doffer channel 6 .

In the positional arrangement of the processing area 2.1, the conveying rollers 10, 14, 15 and 17 are structurally identical, so the drawing roller 10 will be described below as an example. Each delivery roller is formed by a godet 23 and a bypass roller 24 assigned to the godet 23 . The godet 23 is driven by a separate drive 25 . The separate drive 25 is preferably formed by an electric motor. The bypass roller 24 is mounted in a freely rotatable manner, wherein the thread 38 is guided in a multi-winding manner via the godet roller 23 and the bypass roller 24 .

In the positional layout of the processing area 2.1 shown in FIG. 2, there are working groups in the individual processing stations in order to stretch and crimp an incoming filament 38 in a basic manner. For this purpose, the filaments 38 are drawn off the feed bobbin 8 via the take-off roll 10 and guided to the false twisting zone. A false twist is produced in the filament 38 by the false twist texturing unit 13 at the end of the false twist zone as far back as the primary heating device 11 . Inside the primary heating device 11 and cooling device 12 , the setting of the crimps caused by the crimping deformation takes place in the multifilament filaments 38 . Filaments 38 are drawn from the false twist zone by draw rolls 14 and drawn. To this end, the stretching roll 14 is driven at a faster speed than the pulling roll 10 . After the filaments 38 have been crimped, further processing takes place by eddy current texturing and heating. The filament 38 is then wound up into a package 21 .

For handling the device, an operating channel 5 is formed between the module frame 4.1 and the working frame 4.2. The working group on the module frame 4 . 1 and the working group on the working frame 4 . 2 can thus advantageously be operated by an operator from the operating channel 5 . A doffer channel 6 is provided on the longitudinal side of the winding frame 4.3 for loading and unloading the bobbins 21 .

In order to describe in detail the positional arrangement of the processing station 2.1 in the area of the access to the plant, several views of a section of the module rack 4.1 of the processing area 2.1 are shown in FIG. 3 . In this case, a front view of the working module 3.1 is shown in FIG. 3.1 and a rear view of the working module 3.1 is shown in FIG. 3.2. The following description is valid for both views, as long as one of the figures is not explicitly referenced.

The working module 3.1 is replaceably arranged on the module frame 4.1 through a plurality of fixing pieces 27. The module rack 4 . 1 has a plurality of module positions 47 here. A total of three module positions 47.1, 47.2 and 47.3 are formed on the module rack 4.1. Fix job module 3.1 in module position 47.1. The operation module 3.1 of the processing area 2.1 has a set of pulling rollers 10 . Three adjacent pulling rolls 10.1, 10.2 and 10.3 are shown in Figures 3.1 and 3.2, respectively. Each pulling roller 10.1, 10.2 and 10.3 is driven by a separate drive 25.1, 25.2 and 25.3 respectively. Thus the separate drive 25.1 drives the pulling roller 10.1 and the separate drive 25.2 drives the pulling roller 10.2. Each pulling roller 10.1, 10.2, 10.3 etc. of the working station pulls a filament 38 from a feed bobbin through a yarn guide 9.1. All individual drives 25 of the pulling rollers 10 are connected to an electrical distributor 48 on the working module 3 . 1 . The electrical distributor 48 has a plurality of plug connections 49 . The electrical connection of the individual drive 25 of the pulling roller 10 takes place via a plug connection 49 and an electrical distributor 48 . For this purpose, the individual drives 25 are preferably controlled via a combined frequency converter. The combined frequency converter can not only be a component of the electrical distributor 48 but also be arranged externally in an electronics unit assigned to the processing area 2.1.

FIG. 4 shows the positional layout of adjacent processing areas 2.2 of the exemplary embodiment with the aid of a cross-sectional view of the processing area 2.2. The location layout of the processing station 2.2 is basically the same as the location layout of the processing location 2.1. Therefore, only the differences in the location layout will be described below with reference to the above description. For the sake of clarity, structural components with the same function are provided with the same reference numerals.

Two work modules 3.1 and 3.2 are arranged one above the other on the module rack 4.1 in the entry area of the processing area 2.2. The working module 3.1 supports the pulling rollers 10 of the processing positions of the processing area 2.2. The structure of the operation module 3.1 is the same as that of the operation modules arranged in the adjacent processing area 2.1. So please refer to the description above. A delivery roller 29 and a wire feed station 36 are provided for each processing station on the second working module 3.2. In the thread feed station 36 on the working module 3.2, a feed bobbin 37 is fastened at each processing station, on which an additional thread 39 is provided. This additional filament 39 is drawn off via the delivery roller 29 on the working module 3.2 and is conveyed to the stretching roller 14 via deflection guide rollers 41.1 and 41.2 arranged above the operating channel 5. In the eddy current texturing device 40 below the draw roll 14, the additional filaments are combined with the filaments 38 to form a composite filament.

The location arrangement of the processing area 2 . 2 therefore includes additional work groups in order to process a composite filament in each case in the auxiliary processing stations of the processing area 2 . 2 . For example, an elastic fiber filament can be added to the crimped filament 38 as an additional filament. For this purpose, the filaments 38 in each processing position of the processing zone 2.2 are drawn by means of the take-off rollers 10 and transported to the false twisting zone. The additional filament 39 is pulled off the feed bobbin 37 via the delivery roller 29 via the yarn guide 35 arranged on the working module 3 . 2 in each processing station. In this case, the feed bobbin 37 is arranged at the wire feed position 36 on the working module 3.2. The additional filaments 39 are guided directly to the draw roll 14 via deflection guide rolls 41.1 and 41.2 on the false twist zone. After the filaments 38 have been crimped and stretched, the filaments 38 and the additional filaments 39 are recombined in an eddy current texturing device 40 . The composite filament produced in this way is wound up into a package 21 after heat treatment in the secondary heating device 16 .

In order to explain the work modules 3.1 and 3.2 in detail, the entry area of the processing area 2.2 is schematically shown in different views in FIGS. 5.1 and 5.2. FIG. 5.1 shows an enlarged detail in a front view from the operating channel 5 and FIG. 5.2 shows an enlarged detail of the rear side of the module rack 4.1. The module positions 47.1 and 47.2 of the module rack 4.1 in the processing area 2.2 each have working modules 3.1 and 3.2. The operation module 3.1 in the processing area 2.2 is exactly the same as the operation module 3.1 in the processing area 2.1. So please refer to the description above.

The working module 3.2 has a set of output rollers 29 of the processing area 2.2. The first three output rollers 29.1, 29.2, 29.3 of this set are shown in Fig. 5.1. Each delivery roll 29 is formed by a driven godet roll 31 and a bypass roll 30 . The godet 31 is driven by a separate drive 33, of which the separate drives 33.1, 33.2 and 33.3 of the first three output rollers 29.1, 29.2 and 29.3 are shown. For supplying the individual drive 33 , the working module 3 . 2 also has an electrical distributor 48 , which is coupled to the individual drive 33 of the output roller 29 . The electrical distributor 48 is connected via a plug connection 49 to an external power supply and control unit.

On the working module 3.2, a wire feeding station 36 is formed below the output roller 29 of each processing station of the processing area 2.2, which is used to support a feeding bobbin 37. A yarn guide 35 is arranged on the working module 3 . As a result, two filaments 38 and 39 can be drawn for each processing location by means of the working modules 3.1 and 3.2 and processed by subsequent working units within the processing zone 2.2 to form a composite filament. The control of the work groups of the processing area 2.2 is determined here by the associated area control unit 42.2.

The subsequent processing areas in this embodiment may each have a location layout, which corresponds to the location layout of the processing area 2.1 in FIG. 2 or the location layout of the processing area 2.2 in FIG. 4 . However, the at least one processing position in this embodiment can also have a different arrangement of the third position for processing other filament types. However, such false twist texturing machines are usually operated with a few different position layouts in the processing area.

In the above-mentioned embodiments, the location layout of the processing area is mainly changed by additional working groups, which are basically arranged in the entrance area of the equipment. In principle, all working groups arranged within the station arrangement are suitable for producing changes in the station arrangement. Thus, for example, the positional layout of the processing zone 2.1 in the present exemplary embodiment can be changed such that the secondary heating device 16 is not operated, so that a false-twisted filament is wound into a package without heat treatment. It is likewise possible to use a primary heating device 11 in the form of a non-contact heater in a processing zone, while a contact heater is used as primary heating device 11 for an adjacent processing zone. Nor is the invention limited to the arrangement of the working modules on only one module rack located in the access area. The working frame is therefore also suitable in particular as a module frame for accommodating one or more working modules comprising one or more working machine groups. In particular, in the exemplary embodiment described above, a working module is arranged between the eddy current texturing device 40 and the stretching roller 14, which is designed in a manner corresponding to the working module 3.1. An additional delivery roll is therefore arranged upstream of the eddy current texturing device 40 , so that an independent tension adjustment is possible for the eddy texturing of the filaments.

FIG. 6 shows a further embodiment of a working module 3 as can be used, for example, in one of the processing areas. The embodiment of the working module 3 shown in FIG. 3.1 is particularly suitable for processing composite filaments. For this reason, the pulling roller 10 and the output roller 29 are jointly arranged on the working module 3 . The structure of the work module 3 of a machining station is shown in FIG. 6.1. A yarn feeding station 36 and a yarn guide 35 are assigned to the output roller 29 on the working module 3 . A feed bobbin 37 is fixed in the feed position 36 . The pulling roller 10 and delivery roller 29 are preferably arranged on the working module 2 in different filament flow planes, so that the two parallel-moving filaments are guided to the processing position without additional deflection.

Another exemplary embodiment of a working module 3 is shown in FIG. 6.2 , wherein the working module 3 has a pulling roller and a further delivery roller 29 . The two delivery rolls consist of a bypass roll and a godet roll respectively. Between delivery rollers 10 and 29 an eddy current deformation device 40 is fastened to the working module. The swirl texturing device 40 is connected to a compressed air source (not shown here), so that the thread 38 guided through the thread channel is swirled by a stream of compressed air. This pretreatment of the false twist crimped filament 38 can improve the bulkiness of the filament in the crimped state.

Another exemplary embodiment of a working module 3 is schematically shown in FIG. 7 in a partial view of a processing station. In this case, the working module 3 is shown in a first configuration in FIG. 7.1 and in a second configuration in FIG. 7.2 . In the embodiment of the working module 3 shown in FIG. 7.1, the pulling roller 10 already described above is provided. A plurality of mounting devices 28 are assigned to the pulling roller 10 , by means of which additional working units can be fastened. In the exemplary embodiment shown in FIG. 7.1 , the working module 3 has no additional working group fixed in the mounting device 28 .

In FIG. 7.2 the mounting devices of the working module 3 are occupied by an additional delivery roller 29 and a drafting pin 34 . For this embodiment, a filament 38 is drawn from a feed bobbin by means of the take-off roll 10 at each processing position in the processing zone. From the pulling roll 10 the filament 38 is directed to a first draw zone, which extends between the pulling roll 10 and the output roll 29 . A heated drafting pin 34 is arranged inside the stretching zone. The drafting pin 34 can be heated to a surface temperature of 80° C. to 160° C. here. The draft pin 34 is wound by the filament 38 and pulled by the output roller 29 . For the situation that the filament should only be partly wound on the drafting pin 34, the drafting pin 34 can be equipped with a yarn guide on the operation module 3, which can be placed on the drafting pin 34 in order to adjust a certain winding angle. change its position. The filaments 38 prestretched in this way are guided from the delivery roll 29 to the false twist texturing zone. Other filament flows can correspond to the positional layout of the processing area 2.1 of the exemplary embodiment. The power supply and control of the output rollers 10 and 29 and the drafting pin 34 are carried out through the above-mentioned electrical distributor (not shown here).

The false twist texturing machine according to the invention can therefore process as many different yarn shapes as possible in a particularly flexible manner simultaneously.
