- the control device 64 can expediently be designed such that a respective displacement of the belt 20 by the compensating means, preferably comprising the deflection roller R3, only takes place after a predeterminable time has elapsed from the release of the positioning arm 38 for a respective transfer of the core H into the winding position .
- the lock in the sleeve channel is released, whereupon the positioning arm is pivoted downward.
- a timer for controlling the compensation means is also triggered in order to set a predefinable delay time of, for example, approximately 3 seconds.
- the sleeve-like core is then pressed against the belt.
- the timer triggers the control for the compensating means R3, whereby the belt is displaced so that the tracked core can be transferred to the winding position.
- this position which can be determined in particular by at least one sensor, the belt displacement is stopped.
- the sleeve-like core is now clamped between the winding disks, whereupon the positioning arm is returned to the neutral position. is pivoted back.
- the swiveled out pulley is swiveled in again, whereupon the winding process is started.
- control device 64 is coupled to at least one sensor 76, 78 which monitors the position of the core H or the positioning arm 38, a respective displacement of the belt 20 can also be triggered by the compensating means comprising the deflection roller R3 as a function of the sensor signals concerned.
- a timer is not used. Rather, the position of the core or the positioning arm is monitored via appropriately arranged sensors. As soon as the sensor or sensors in question respond, the sleeve-like core lies on the belt with the correct tension. Then the control device triggers the displacement of the deflection roller R3 assigned to the compensating means, so that the core can be transferred into the winding position.
