Embodiment Construction
[0034] figure 1A winding device 1 is shown very schematically in the form of a double support roll winder. The winding device 1 has two support rollers 2, 3, between which a winding bed 4 is formed, in which a schematically shown mandrel 5 is arranged, onto which a not described in greater detail is wound. Material web. The structural arrangement of such a double backup roll winder is already known.
[0035] The two support rollers 2 , 3 are supported in a frame 6 . Each of the back-up rolls 2,3 has a bearing arrangement supported by a bearing 7,8 at each end of the back-up roll 2,3. Only bearings 7 and 8 are in figure 1 are visible separately.
[0036] This winding device can be operated at maximum conveying speed. The conveying speed is, for example, 2500 m / min or 3000 m / min. This results in a defined number of revolutions and thus a defined rotational frequency of the support rollers 2 , 3 . The winding device is designed for this rotational frequency. The number o...
