Problems solved by technology

[0007] So far, people have tried to solve this problem by setting the first natural frequency of the system, which is the lowest natural frequency, so high that the winding equipment cannot reach this natural frequency during operation

Embodiment Construction

[0034] figure 1 The winding device 1 is shown very clearly in the form of a double backup roll coiler. The winding device 1 has two drum-type support rolls 2, 3, between which a winding bed 4 is formed, in which a schematically shown mandrel 5 is arranged, in which A material web, not shown in detail, is wound up on the mandrel 5 . The construction of such double backup roll coilers is known per se.

[0035] The two support rollers 2 , 3 are supported on a machine frame 6 . Accordingly, each backup roll 2, 3 has a bearing arrangement with a bearing 7, 8 on each roll end. figure 1 Only a single bearing 7, 8 is shown respectively.

[0036]This coiling device can run at maximum input speed. The input speed is, for example, 2500 m / min or 3000 m / min. A certain number of revolutions and thus a certain rotational frequency of the support rollers 2 , 3 can thus be achieved. The winding device is configured for this rotational frequency. When the winding process starts, the num...

Abstract

The invention relates to a device for winding a material web on a mandrel (5), said device having at least one roller (2, 3), on which the reel is supported during winding and which Rotates at a maximum rotational frequency, wherein the rollers are mounted in bearing arrangements via a bearing (7, 8) at each roller end, and the rollers (2, 3) and their bearing arrangements have a first natural frequency. It is also desirable to be able to wind vibration-critical material webs with as few problems as possible. For this purpose, the first natural frequency can be set to be lower than the maximum rotational frequency of the roller.

Description

technical field [0001] The invention relates to a device for winding a material web into a reel, said device having at least one roller on which the reel is supported during winding and rotated at a maximum rotational frequency during winding, Wherein, the roller is supported in the bearing device by a bearing at each roller end, and the roller and its bearing device have a first natural frequency. [0002] Furthermore, the invention relates to a method for winding a material web into a reel, wherein the reel is mounted on at least one roller which rotates at a maximum rotational frequency during winding. Background technique [0003] The invention will be described below using a paper web as an example of a material web. However, the invention is also applicable to other webs of material where similar problems arise. The equipment for winding the paper web achieves a wide working width of more than 10 meters. Among them, in the case of longitudinal division of the web, t...
