Problems solved by technology

Unrelated to this, operators of paper mills face another fundamental problem: the pursuit of high production speeds in order to maintain competitiveness and high productivity
However, the result is often unsatisfactory roll structures
Especially in the case of demanding paper grades, i.e. paper grades with a coefficient of friction of more than 0.55 and especially more than 0.7, the roll structure at high production speeds is often unsatisfactory
Furthermore the productivity, that is to say above all the winding speed can hardly be increased beyond the reliable transfer of 2800 m / min

Embodiment Construction

[0095] According to the material roll winding device 1 of the present invention in figure 1 and figure 2 The preferred embodiment shown in is realized in conjunction with an idler roll winding device which has a roller arrangement in its winding area. The roller arrangement has two rollers 6 designed as carrier rollers, at least one of which is drivable. Both rollers 6 are preferably drivable and connected to a common control / regulation unit 19 . In this case, it has proven to be suitable to adjust the rotational speed of the first roller 6 and to adjust the torque of the second roller 6 when the material web M, in particular the paper web, is in the running direction, ie the x-direction. The shafts of the rollers 6 are supported on roller bearings 4 , 5 which can be located at different height levels in the z-direction. Furthermore, the rollers 6 can have diameters of different thicknesses. Of course, at least one of the two rollers 6 can also have a coating or armor whi...

Abstract

The invention relates to a roll winding device, which is used for winding a sheet of material, particularly a paper web or a cardboard web to at least a roll on at least a winding core and a preferably winding cylinder, during winding, at least a roller supported on a rolling bearing is attached to the roll, and at least a moveable rolling bearing is connected with a support part via a damping unit. The damping unit comprises a cylinder and a piston movably arranged in the cylinder. In order to improve a winding structure and particularly stabilize relationship in winding scope, a frictionless sealing is provided between the cylinder and the piston. An independent claim is also included for a beneficial method for winding a sheet of material.

Description

technical field [0001] The invention relates to a roll winding device for winding a material web, in particular a paper or cardboard web, on at least one winding core, preferably a mandrel, into at least one roll, wherein When winding, at least one roller supported in the rolling bearing is against the material roll, and at least one movable rolling bearing is connected with the supporting part through the shock absorbing device, and the supporting part includes a cylinder and is movably arranged on the cylinder Piston in barrel. [0002] The invention also relates to a method for winding a web of winding material, in particular a web of paper or cardboard, into a roll by means of a roll winding device on at least one winding core, preferably a mandrel. Background technique [0003] The invention is described below in connection with the treatment of paper webs. However, the invention can also be used correspondingly in other webs which are treated similarly. This is, but...
