Definitions
- the invention relates to a method for upsetting a multifilament thread according to the preamble of claim 1 and a device for Implementation of the method according to the preamble of claim 11.
- a Crimping device for example, designed as a texturing nozzle, which one Thread channel in which a thread through a hot medium, preferably air.
- the thread channel opens into one Stowage chamber.
- the thread plug is formed within the stuffer box.
- the thread is deposited in loops on the surface of the thread plug and is compacted by the conveyor, which is above the thread plug can escape from the stuffer box through slots.
- the thread plug will then led out of the stuffer box and by means of a subsequent Cooling device cooled down. After cooling, the thread plug becomes curled thread dissolved.
- the crimp of the thread is in its intensity and stability mainly due to the formation of plugs and the thermal treatment of the Thread plug affected.
- the temperature and pressure of the Funding also includes the dwell time of the thread plug during the thermal Treatment parameters that significantly influence the ripple result.
- the supply and / or the has long been known Control the speed of withdrawal of the thread in such a way that a uniform Formation of the thread plug is observed during the process.
- a such a device and such a method are for example in DE 1 236 126. This is used to monitor the thread plug Detection point at the end of the thread plug detected in its position and on a predetermined level by changing the take-off speed of the thread regulated.
- the known method is only suitable to a limited extent with a thread to produce even crimp as there is no direct interference in the Formation of the thread plug enables. For example, fluctuations too considerable in the temperature or the pressure of the pumped medium Differences in the crimp of the thread lead.
- DE 23 24 827 proposed a method and a device for which the heat supply for thread plug depending on the location of the Dissolution point of the thread plug is regulated.

To do this, change the Take-off speed recurring at specified times by a Comparison between a setpoint and an actual value of Take-off speed determined.
- the setpoint of the take-off speed can correspond to a stored optimal setting, for which corresponding Parameter settings of the crimps include.
- the particularly preferred embodiment variant of the invention is characterized in that the position of the Resolution point and thus the controlled variable directly for the control of the parameter the crimping device is used. For this, the Take-off speed recurring at specified times on one specified setpoint. At the same time, the resolution point of the Thread stopper detected in its position. If there is a change in the location of the Resolution point, a corresponding signal for controlling the Parameters of the crimper generated.
- the type of change in position of the thread plug corresponding Parameter changes generated.
- the signal causes a parameter change that leads to a reduction in the Packing density of the thread plug leads.
- an extension of the Thread plug causes the signal to change parameters, resulting in a Increasing the packing density of the thread plug leads.
- the change in the pull-off speed can be done directly by a Take up device so that the thread without major Tension fluctuations are wound into a coil.
- the thread is threaded using one of the Subtracting cooling device subtracted. There is a thread tension controlled winding of the thread.
- control of the crimping device and the regulation of the thread plug length is in the invention Device realized in that a control device for control at least one parameter influencing the formation of the thread plug Crimping device is provided.
- the control device is by a Signal line connected to the control device, so that for example Controlled variable, a command variable, a manipulated variable or one of the variables modified signal of the control device can be given.
- the development of the device according to the invention is according to claim 13 particularly advantageous to monitor the effects of the control.
- the situation is briefly regulated at a certain point in time of the dissolving point or the length of the thread stopper. Doing so the position of the resolution point continues to be detected by the sensor.
- the sensor delivers thus directly a measured variable, which is used as a measure of the parameter change of the Crimping device can be used.
- the further education enables thus the production of a crimped thread in which the Ripple quality kept iteratively to a uniform high quality becomes.
- the device according to claim 14 is particularly good suitable.
- the control device is continuously given a sensor signal, so that the control is superimposed on the control at the same time is executable.
- FIGS. 1 to 3 each belong to one Spinning plant for the production of a crimped multifilament thread. It was in Figures 1 to 3 dispensed with the representation of the spinning device.
- a thread is made from a thermoplastic melt in the spinning device a variety of filaments extruded and spun. The thread becomes after Cooling of the filaments withdrawn from one or more supply plants and if necessary stretched.

- the thread 1 loops around the godet 5 and the overflow roller 6 several times before the thread 1 of the godet 5 runs to the crimping device 2.
- the thread 1 becomes a thread plug formed by placing the thread in loops and compacting it.
- the one from the Crimping device 2 emerging thread plug 3 is then in a Cooling device 4 guided along a cooling section.
- the cooling section is through a cooling tube 7 is formed.
- the cooling tube preferably has an air-permeable Wall on a sensor 18 is arranged in the end region of the cooling tube 7.

- the optimum setting data for the crimp, thread stopper length and the take-off speed are determined at the beginning of a process and stored in the control device 17 and the control device 20. With these setting data, the thread 1 is crimped and wound into a bobbin. If the case now occurs that the thread plug is too loose, so that the thread is too weakly crimped, the length of the thread plug will inevitably increase. As a result, the position of the opening point of the thread plug 3 will shift towards the end of the cooling tube 7. This change in position is detected by the sensor 18 and displayed to the control device 17.
- the positional deviation between a solo position L target and an actual position L actual is converted into a manipulated variable which is given to the godet drive 11 as a control variable.
- the control variable causes a higher speed of the godet 10, so that the Pull-off speed of thread 1 increases. This shifts the Dissolution point of the thread plug in the direction of the target position. An overflow of the Thread plug from the cooling tube 7 is avoided.
- the Control device 17 a signal which through the signal line 19 of the Control device 20 is abandoned.
- the control device 20 is then change at least one parameter of the crimping device 2 such that the thread plug volume decreases.
- the packing density of the thread plug increases so that a greater crimp of the thread is achieved. Regardless of the change in packing density remains throughout Time the dissolving point of the thread plug in a determined by the regulation Target position. However, the increased controlled take-off speed is due to the changed packing density now slowly returned to the original value.
