Definitions
- the invention relates to a false twist texturing machine for false twist texturing of several synthetic threads according to the preamble of claim 1.
- false twist texturing machines of this type are used to curl melt-spun multifilament threads and, as far as possible, to simulate the threads in their structure and appearance to the natural fibers.
- the false twist texturing machine has a multiplicity of processing points, the thread being treated in each processing point by a plurality of position units for finishing.
- the thread is drawn and crimped in a false twist zone and, after crimping, is wound into a bobbin.
- the positioning units such as delivery units, heating device, cooling device and false twist unit, are fastened in a machine part so that a predetermined thread path is set.
- Such a false twist texturing machine is known for example from EP 0 641 877. False twist texturing machines of this type are constructed in such a way that a thread with a defined thread path and predetermined thread treatment is optimally crimped in each processing point.
- the false twist texturing machine has an inlet module for receiving the take-off delivery unit.
- Several intake devices for additional process units for guiding and treating a thread or several threads are provided on the inlet module.
- the inlet module thus ensures a flexible arrangement of additional process units that are required compared to a standard process to produce special fancy yarns.
- the invention has the particular advantage that for each yarn type that can be produced, an associated and already predetermined thread path can be selected by correspondingly arranging the process units in the inlet module.
- the additional process units are exchangeably connected to the inlet module by the receiving devices. This enables the process to be changed quickly, for example from the production of a standard yarn to the production of a fancy yarn.
- the advantageous development of the invention according to claim 3 is particularly suitable for firmly connecting the process units to the inlet module via the receiving devices.
- the process units that are required for the respective process are activated.
- Additional processing units, a drawing pin, a tanging device and / or a spool template can optionally be provided as additional process units for each processing point.
- the bobbin feed can be used to feed a second thread at the inlet or the process in order to produce a composite thread in the processing point.
- a thread drawn off the take-off mechanism could be additionally treated by means of a drawing pin or a tanging device before the false twist texturing.
- an operating aisle is formed between the inlet module and a process module.
- the process module carries at least some of the position units, such as false twist units and delivery units.
- the process units and the positioning units can preferably be operated by an operator from the operating aisle.
- the development of the invention according to claim 6 and claim 7 ensures that in the false twist texturing machine a non-crossing thread course is set. Due to the little deflected thread path, the thread can be guided in a very stable thread path regardless of the type of thread.
- the arrangement of the heating device of the cooling device above the service aisle also has the advantage that a sufficient length for heat treatment and cooling of the false twist thread can be realized.
- the modules combined to form a frame part also achieve a compact construction of the false twist texturing machine.
- Fadens is a second
- Heating device arranged on the underside of the frame part, which carries the process module and the winding module.
- the heater is preferably in arranged in a horizontally inclined position in order to produce a uniform heating of the thread by contact.
- the delivery mechanisms in each case by a godet wrapped in multiple threads with an associated overflow roller.
- the godet is driven by a single drive independent of neighboring supply plants.
- the godet is also particularly advantageous for changing the thread circulation, so that no further thread guide elements are required, for example, in the entrance area and in the exit area of the second heating device.
- the advantageous development of the invention according to claim 10 is particularly suitable for producing composite threads from, for example, a crimped thread and an elastic thread, which are brought together by a tang device immediately after the crimping.
- a tangle device is arranged on the process module in the thread run behind the false twist unit.
- FIG. 1 schematically shows a view of an embodiment of the false twist texturing machine according to the invention

- the tang device 38 is arranged on the process module 2 between the stretching delivery unit 14 and an additional delivery unit 39 arranged upstream of the set delivery unit 15. With the additional delivery mechanism 39, the thread tensions required for the connection of the two threads 36 and 37 can thus advantageously be set.
- the composite thread formed from the threads 36 and 37 is then guided via the set delivery unit 15 through the secondary heating device 16 and by means of the delivery unit 17 to the winding device 18.
- the embodiment of the false twist texturing machine according to the invention shown in FIG. 4 can, however, also be used for false twist texturing of a thread without the provision of a second thread.
- the delivery mechanism 29 and the coil feed 33 on the inlet module 3 could be omitted.
- the thread 36 is swirled before the second heat treatment.
- the exemplary embodiments of the false twist Texmriermaschine shown in FIGS. 1 and 2 are exemplary in the design and structure of the position units.

The flexible design and design of the inlet module with additional process units increases the use Such false twist texturing machines to a considerable extent. Complicated conversion measures are not necessary.
