  • Paper webs are produced in relatively large widths of up to more than 11 m in a paper machine.
  • the production is almost endless.
  • the machine direction of the paper machine defines the longitudinal direction for all machines and devices located in the paper factory and the transverse direction perpendicular thereto in the horizontal plane.

  • Y-direction the height direction perpendicular to a plane defined by these two directions called vertical direction as Z-direction.
  • the paper web produced is wound in full width onto a winding core. This winding core is replaced cyclically, usually during production.
  • the resulting web-width winding roll is commonly referred to as mother roll or full tambour.
  • the paper web wound on a mother roll has to be cut into several parallel partial webs whose widths are suitable for the respective later user. These widths can vary greatly from case to case, so that the division of the paper web is usually made according to an individually definable pattern.
  • the partial webs are then wound into winding rolls, which are called Generalbahn- or finished rolling and are issued together as a so-called roll throw.
  • the pattern can be changed from roll throw to roll throw.
  • the slitting and winding is conveniently carried out in a single machine, which is then often referred to as a slitter.
  • winding devices described above ie those for the production of parent rolls as well as those for the production of partial web or finished rolls, has in common that the train to be wound up to form a winding roll forms a winding nip with at least one winding roller on which it is supported or on it on or rests and which is accordingly referred to as a support or support roller.

  • a trouble-free run in the unwinding of the printing machine is necessary, which requires a central winding roll structure, a symmetrical sleeve seat and a favorable winding hardness profile in the winding roll.
  • the individual winding roll should be free of winding defects, in particular free of crevices, places, bars (which are also known as washboard pattern or rope markings), star formation, lateral positional shifts and markings on the material web surface.
  • the invention is therefore based on the object to further develop a device for winding a web on a winding roll such that the winding structure improves and in particular the conditions in the winding area are stabilized.
  • the object of the invention is to improve the winding structure over long process sections and to stabilize the winding process.
  • the roll winding device comprises a winding hardness generating device which is free of contact with the at least one winding roll.
  • winding hardness is understood to mean the web tension wrapped in the individual layers of the winding roll.
  • Paper and paperboard belong to the group of biopolymers as pulp-based fiber webs and are consequently characterized under load by a viscoelastic behavior, ie have a partially elastic, partially viscous behavior. Such behavior is due to a delayed equilibration of the Macromolecules to each other during and following an external load. At first, therefore, the strain increases with time. After relieving the material then relaxes only incomplete, the remaining energy is degraded time-dependent in the form of flow processes (retardation). This always leaves a certain amount of plastic strain.
  • At least one winding hardness generating device is provided, which is free of contact with the at least one wound roll to be produced, wherein the winding hardness generating device is characterized in that the increase in the web tension generated by it at least not complete by relaxation or Retardationsvone before wrapping in the Winding roll is dismantled. It is particularly preferred if the winding hardness generating device has an efficiency of at least 20%, wherein the efficiency is understood as the ratio of actually preserved winding hardness to applied web tension increase.
  • the preserved winding hardness increase rate is measured after completion of the winding process and compared with the winding hardness of a winding roll, which was wound without the influence of the winding hardness generating device according to the invention but otherwise the same circumstances.
  • the aim is even an efficiency of at least 30%, in particular at least 50%, very particularly at least 70%.
  • An efficiency below a few percent, which may well be well below today still common Bruzugschwankept is +/- 10%, is no longer understood as winding hardness generating device in the strict sense.
  • the achievable efficiency can be actively influenced within a certain scope.
  • the distance of the winding hardness generating device to the forming winding roll can be varied.

  • the conditions in the winding, so in particular in the aforementioned winding system can be stabilized and winding errors can be reduced or even completely avoided.
  • the voltage or elongation which can be preserved in the material web by means of the winding hardness generating device (and at least partially preserved in the winding roller) can be modifiable, preferably adjustable, particularly preferably controllable or controllable.
  • the at least one winding hardness generating device is arranged immediately before the first nip formed by the at least one roller and the at least one winding roller.
  • the winding hardness generating device can be seen in the web running direction a few centimeters to a few meters away from said nip.
  • a guide roller which is otherwise without influence, is arranged between.
  • no arrangements which are not directly related to the winding hardness-generating device are provided between it and the nip. By such designs, a particularly high efficiency can be achieved.
  • winding hardness generating device is sectioned in CD or if several winding hardness generating devices are arranged side by side in CD.
  • the individual sections or the winding hardness generating devices arranged next to each other can preferably be controlled individually or in groups.
  • divided or undivided webs in the CD direction continuously or in sections with different web tension increases can be acted upon.
  • the winding structure Seen individually over the width of the material web.
  • transverse profile fluctuations, but also uneven machine influences, such as vibration tendencies or irregularities of the rollers acting on the at least one winding roller can be effectively compensated, whereby the winding structure can be improved and the conditions in the winding area are particularly well stabilized.
  • the winding hardness generating device is controllable and / or controllable on the basis of measurement data which are determined before the material web enters the roll winding device, that is to say in particular in a material web production machine, for example a paper machine.
  • the winding hardness generating means is operatively connected to a feed-forward, which feedforward obtains measurement data obtained during the material web generation.

  • the person skilled in the art distinguishes between two basic types of construction, namely the carrier roll and the backup roll scooter.
  • each individual roll to be wound is wound in a separate winding station.

  • the rolls are wound up together, as a complete throw. As a rule, this is done by means of a circumferential winding, for which purpose at least one of the two support rollers can be driven. If a winding shaft is used, a center winding or a combination of both can also take place.
  • winding rolls wound around a band and / or around the forming winding rolls from a support into a support position are also understood to mean supporting or supporting rolls.
  • the winding hardness generating device according to the invention can be used particularly effectively since such devices generally offline, that is, from the material webmaking machine, here the paper machine, are separated and therefore confronted as discontinuous devices with additional special problems: they must namely follow the continuously developed production output of the paper machine. Since set-up, acceleration and deceleration times occur relatively frequently in accordance with the task of reducing the format, this can only be compensated for by significantly higher production speeds. However, such high demands on the winding speeds involve an additional high risk potential due to vibrations occurring.
  • the winding to be produced hardly takes on an ideal round shape. Small winding errors, for example, due to slight profile fluctuations of the paper web to be wound, add up with each full wrapping. It can then come with each revolution also contact losses or at least different line loads. Paper-technological correlations, such as compressibility or coefficient of friction of the web, then lead to inhomogeneous roles. Already at a semi-critical speed, which corresponds to about half the resonance speed of the role, it comes to strong deformation of the role. These deformations are also referred to as s2 impact or 2f impact and, in a constant interaction, also have a direct effect on the components of the reel winder that are in contact with the reel, that is to say in particular on the reels to be produced.
  • the winding hardness generating device comprises a web deflection device, by means of which the material web is stretchable such that at least part of the material web elongation is conservable in the wound roll to be produced.
  • Such a web deflection device can advantageously consist of a roller which penetrates into the plane of the moving material web. In this way, the web is deflected from its direction. While maintaining all environmental parameters, the material web is then forced to bypass the "obstacle", ie the roll surface, which has penetrated into its raceway at a locally higher speed, which causes tensile stresses in the material web which essentially depend on the penetration depth of the roll. It is also conceivable that the roller of the material web independently, for example centrally, is driven and subjected to a differential speed. The tensile stresses thus produced in the material web have an effect on elongation, which would be degradable via the relationships explained above only after a certain duration. According to the present invention, however, the material web is disturbed during the stress relaxation by the friction forces which become effective during the formation of the lap during the relaxation and retardation processes which have not yet been completed and thus preserved in the forming wound roll.
  • such a web deflection device consists of several rolls or roll segments arranged side by side in CD.
  • the rolls or roll segments can be very narrow in order to allow the most individual possible web treatment. Preferably, they have a width between 5cm and 30cm. In practice, however, it is already advantageous if a width between 50cm to 80cm or even up to 100 cm is maintained.
  • the individual rollers or roller sections then have adjustable, support bearings which are movable by adjusting devices themselves or via the connecting elements connected to them. It is particularly advantageous if a drive is provided by means of which a plurality of adjusting devices can be actuated. Through the use of a central drive for multiple adjustment is Saved space and equipment for the winding hardness generating device.
  • the drive with the adjusting devices via a clutch and disengageable. So it is possible in a simple way to control each adjustment separately and operate.
  • the adjusting device is formed by a spindle drive.
  • the drive acts on a spindle in a fixed spindle nut or on a rotatably mounted spindle nut connected to the spindle. As a result, the spindle is moved axially, and you can also adjust the or attached to this spindle (n) support bearing.
  • the drive is advantageously one that includes a circulating belt. Such a belt or a drive belt takes up very little space and can be easily integrated into the carrier of the adjusting device.
  • the adjusting device is designed as an eccentric.
  • the aligned in the Y direction of the fibrous web drive acts on individual cam gear elements, which are designed as eccentric.
  • Such a trained transmission is able to transmit high forces.
  • the adjusting device has a locking element.
  • This locking element serves to ensure that the adjusted support bearing retains its new position during production.
  • the thread pitch of the spindle has a self-locking.
  • an additional clamping mechanism can be used. It is particularly advantageous if a direct or indirect position detection is provided for the support bearing, whereby the control or adjustable adjustment during production is particularly simplified.
  • the winding hardness generating device comprises a nip generating device, by means of which the material web is stretchable such that at least part of the material web elongation is conservable in the wound roll to be produced.
  • the nip acting on the material web-a Nips- can apply a tensile stress in a web.
  • the nip is formed from at least one pair of rollers.
  • the nip can be varied in height and can be brought into contact with the material web again and again.
  • Significant influencing parameters, while in contact, are the forces acting in the nip normal to the running direction of the material web and the surface properties of the nip-producing rolls.

  • the winding hardness generating device comprises a device by means of which at least the surface of the material web can be heated or cooled.
  • the material web to be treated like any other material, expands slightly.
  • the material web which has only been heated for a short time, cools down again, a contracting being limited by the already acting frictional forces with the winding layer or layers in contact with the considered material web region. This compensates for part of the web tension receded between the winding hardness generating device and the winding roll and artificially increases the efficiency of the winding hardness generating device.
  • the winding hardness generating device comprises a device by means of which at least the surface of the material web can be subjected to moisture.
  • the expansion behavior and the coefficient of friction of the material web can be influenced. Moistening should then increase the total residual moisture content of the paper web by about 0.3% to 2%.
  • the winding hardness generating device is clockable.
  • a clocking of the amount of voltage introduced into the material web can positively influence the uniformity of the course of the winding hardness. It is assumed that the relaxation and the retardation process are disturbed and in consequence where the difference in the energetic degradation of the introduced voltage is higher or at least equivalent, as the loss of difference due to the short load breaks when applying the voltage and the voltage curve within the material greatly homogenized. Depending on the grade and grammage, high frequency clocking with comparatively small amplitudes may be preferred.
  • the contact time for generating the tension or elongation that can be introduced into the material web by the winding hardness-generating device can be changed in its amount, preferably adjustable, particularly preferably controllable or controllable.
