- the difference between the belt speed of the metal belt and the speed of at least one of the drive rollers is controlled by a controller such that the difference between the belt speed and the surface speed of the driver rollers does not exceed an adjustable limit.
- the drives of the driver rollers and the winding mandrel are controlled by the regulation of the contact pressure of the driver rollers against the belt and that the target speeds of the drives are set so that between the driver rollers a predetermined relative speed occurs and the setpoint the contact force of the driver rollers is controlled so that a predetermined train in the metal strip in the area between the driver rollers and a coil wound on the winding mandrel acts.
- the driver setting force or the drive torque of the at least one driven driver roller is predetermined such that the difference between the belt speed and the surface speed of the driven driver roller does not exceed an adjustable limit value.
- the speed of the winding mandrel is regulated.
- the drive torque of the mandrel is predetermined so that the differences between the belt speed and the surface speed of at least one of the driver rollers not an adjustable limit exceed.
- the belt speed is measured without contact or by a speed measuring roller which is pressed against the metal belt.
- the belt speed is determined by measuring the rotational speed of the winding mandrel and the diameter of the wound on the winding mandrel tape roll.
- the diameter of the wound on the winding mandrel Federal of the metal strip can be measured.
- the force is regulated, exert the force generator on the driver rollers.
- the operator additionally to specify force correction values for the force control on the driver rollers.
- the correction of the contact force of the driver rollers with a proportional-integral controller from the difference of the setpoint and the actual value for the train in the metal band in the area between the driver rollers and wound on the mandrel collar is determined ,
- Advantageous is a method in which the temporal correction of the contact force of the driver rollers with a three-point controller from the difference of the setpoint and the actual value of the train in the metal strip between the driver rollers and the collar is determined.
- the invention also relates to a device for winding a Metal band to a collar for carrying out the method described above.
- Fig. 1 is a side schematic view of a winding device for
- FIG. 2 is a schematic plan view of the driver rollers and the mandrel in connection with the respective drives
- Fig. 3 shows the control scheme for calculating the rotational speeds of the driver rollers and the winding mandrel
- a winding device (FIG. 1) with a winding mandrel 1 serves to wind up a metal strip 2, which is wound on a bundle or band wound coil (coil) 12 of the metal strip 2.
- the metal strip 2 reaches the winding device typically on a horizontal roller table, on which it is deflected by two against the metal strip 2 and against each other employed driver rollers 3, 4 to the mandrel 1 and wound there to the collar 12.
- Driver rollers 3, 4 give the metal band 2 the necessary train.
- the driver rollers 3, 4 and the mandrel 1 are each driven by a motor 7, 8 and 19 directly or alternatively via gear. In one embodiment of the invention, only one of the driver rollers 3, 4 is driven, wherein the other driver roller 3, 4 is entrained. Preferably, the moments of the driver rollers 3, 4 or of the winding mandrel 1 can be regulated.
- the speeds of the motors 7, 8 and 19 ( Figure 2) are measured by speed sensors 13, 14 and 20, respectively.

- the collar radius can be calculated from the variable and metrologically determinable diameter of the winding mandrel, the number of turns and the strip thickness counted during the winding process. Alternatively, a direct measurement of the collar radius' with a distance measuring device 1 1 is possible.
- the belt speed v B can also be measured with a contactless sensor 9, 9a, which can be arranged in front of the driver rollers 3, 4 or between the driver rollers 3, 4 and the winding mandrel 1.
- the use of a contacting measuring roller 10 between the driver rollers 3, 4 on the one hand and the collar 12 on the other hand is also possible for measuring the belt speed v B.
- a higher-level control system (FIG. 3) gives setpoint values for the Belt speed v B, soii and the relative speed AV SO II between the driver rollers 3, 4 on the one hand and the tape 2 on the other hand before.
