Definitions
- the invention relates to a device for guiding a tow cable according to the preamble of claim 1.
- the tows or the tows consisting of several tows for withdrawal from the spinning device or for stretching are each guided over a plurality of rollers arranged offset from one another in order to achieve the relatively high withdrawal forces or removal rates to produce high stretching forces.
- the tow is performed with Generalumschlingung or Mehrfachumschlingung on the circumference of the rollers.
- Such a device for guiding a tow is known, for example, from WO 03/097908.
- the rollers are cantilevered on a frame wall.
- the drive of the rollers can be done by a plurality of rollers associated with individual drives or by a group drive.
- the formation of the rolls with individual drives requires a much higher expenditure on equipment compared to the formation of a group drive.
- the group drives known hitherto for a group of rollers are usually based on gear mechanisms which, due to predefined mechanical means, have relatively narrow applications for the operation of the rollers.
- the object of the invention is therefore to develop a device for guiding a tow of the generic type with a group drive for a plurality of rollers such that the rollers are flexible for different applications driven.

- the drive power is used to simultaneously drive all adjacent rollers synchronously.
- the rollers are interconnected with one or more gear means.
- the electric motor is preferably coupled directly to a drive shaft of one of the rollers.
- the electric motor is preferably coupled directly to a drive shaft of one of the rollers.
- the electric motor is preferably formed by a so-called permanent magnet motor.
- the electric motor is designed as a synchronous motor, in which an annular rotor is equipped with a plurality of permanent magnets. This allows an intense and stable magnetic field to be generated in the interior, which is retained even when switching off an external field.
- the synchronous motor has for coupling a shaft section to the rotor.
- a Hohlwellenholzhahme in which the shaft portion can be inserted.
- the shaft portion may be located directly at one end of the drive shaft or at one end of an intermediate shaft, which is connected to the opposite end with the drive shaft.
- an intermediate shaft which is connected to the opposite end with the drive shaft.
- the development of the invention is particularly advantageous, in which the electric motor is connected to a control unit, which is coupled at least with one of a roller associated sensor means.
- the actual value of a rotational speed of one of the drive shafts of the rollers or the peripheral speed of one of the rollers sensed by the sensor means can thus be adjusted and continuously regulated with the respective preset desired value.
- the process uniformity required to guide the tow is particularly ensured.
- a coupling device is advantageously arranged in the drive train between the electric motor and the roller.
- especially steel disc clutches have proven.
- the drive shafts are preferably each assigned a toothed wheel which is engaged with one another.
- each of the drive shafts can be driven without slip with identical speeds.

- the electric motor 6 is connected to the free end of the drive shaft 4.2, which drives the roller 1.2 with its opposite end.
- a control unit 8 is provided, which is coupled to a sensor means 9.
- the sensor means 9 is disposed within the frame wall 2 in the vicinity of the drive shaft 4.2 to detect the drive speed for driving the rollers 1.1 to 1.5.
- the drive shaft 4.2 is rotatably supported by the bearing 7.1 and 7.2 in the frame wall 2. Above the drive shaft 4.2, the drive shaft is held 4.3, which is connected to the roller 1.3.

- the target specification can be given up in the form of a peripheral speed or a rotational speed.
- a spinning cable 10 is continuously guided in the operating state by partial wrapping on the rolls 1.1 to 1.5 and drawn off, for example, from a spinning device or stretched between two adjacent devices with a plurality of rolls.
- the number of rollers shown in Fig. 2 is exemplary for this purpose. Thus, 2, 3, 4 or more rolls can also be driven by such a group drive.
- the actual drive speed of the drive shaft 4.2 is continuously detected by the sensor means 9 and the control unit 8 signals.
- the control unit 8 there is an actual target comparison, so that any difference phenomena can be given up directly by changing or correcting the electric motor 6. This can be on the rollers 1.1 to 1.5 set circumferential speed to be kept substantially constant throughout the operation.
- roller shells When guiding spun cables or spun cable groups, rolls having tempered roller shells are preferably used. It is usual that a tempered fluid is fed to the rollers via the free end of the drive shafts and discharged again. In such rollers, a direct connection of an electric motor at the free end of the drive shaft is not possible.
