- the tensioning device At least predominantly only for compensation of larger during the winding process as a result of increasing wadding belt length changes occurring loop is provided they are dimensioned accordingly, without any Restrictions with regard to the fastest possible winding output in purchase would take. Rather, an appropriate interpretation of the additional provided compensation elements this output speed easily and regardless of the respective dimensioning of the clamping device in the desired way can be increased, which in particular also faster Exchange of the finished wadding roll for a new one, for example with a Sleeve or the like formed core is possible.
- the additional compensation element can therefore be used especially for a quick compensation of usually small Belt length shifts can be designed while the tensioning device for the slower compensation of larger belt length displacements with larger ones forces can be provided. According to the invention regardless of the respective tensioning device, both a relatively quick opening of the Belt loop as well as accelerated winding output possible.
- This advantage of a compensation largely independent of the tensioning device while opening the belt loop and ejecting the wadding is particularly useful in a preferred embodiment in practice, in which the core is rotatable about a fixed axis during the winding process and the Belt tension at least essentially during this winding process the tensioning device can be predetermined. In this case, namely during the Forces to be applied during the winding process in particular also greater than the weight of the wadding.

- the defined pivot axis can, for example, be close to and preferably be arranged below the region of the initially fixed axis of rotation of the core. Basically, however, it is also possible that the defined pivot axis in the area the initially fixed axis of rotation of the core is arranged or with this matches.
- the winding device is the defined pivot axis at a distance from the area of initially fixed axis of rotation of the core and the adjustable pulley pivotable over part of the circumference of the wadding roll so that with their Transfer to the eject position and tightening the belt one preferably rolling surface sloping downwards relative to the horizontal to be ejected wadding and the adjustable pulley at the end the pivoting movement in an area close to another, horizontally outer stationary deflection roller on its facing the wadding to be ejected inner side comes to rest.
