Abstract

The invention provides a device and a method for winding a sheet of material to a winding roll (5). The device has at least one roller (2, 3), on which the winding roll is applied during the winding, wherein the winding roll rotates during the winding with a maximum rotational frequency. The roller (2, 3) is mounted in a bearing device through a bearing (7, 8) at each roller end, wherein the roller (2, 3) and the bearing device have a first natural frequency. The first natural frequency is set to be less than the maximum rotational frequency of the roller for winding the sheet of material at a vibration threshold with fewest problems.

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...

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...
