Definitions

  • the invention relates to a winding device for winding webs of material, in particular fibrous webs in the form of paper, cardboard or tissue webs on sleeves or hubs, with a longitudinal cutting device for dividing the web into individual webs and individual winding stations, which are arranged in two winding lines on both sides of a drivable support roller on which the winding rolls on or lie on winding.
  • Winding devices in the form of back-up roll winders are previously known in a variety of different prior art designs. Representative is here on the publication DE 44 24 848 A1 directed.
  • these subsequent wind-up stations are assigned, which wind each of the individual webs into a wound reel.
  • the individual winding stations are arranged in two winding lines on both sides of a central support roller. These consist of two movable transversely to the direction of web travel support elements, to each of which a rotatable, retractable on one side of the winding tube guide head is attached.
  • the guide heads bear wholly or partly the weight of the bobbins when winding and are either free-running or connected to a rotary drive to additionally influence the tension during winding can.
  • the winding quality is crucial by the contact force or contact force in the winding nip or nip at the contact line between the winding rollers and the support roller through Pressing the bobbins set by means of the guide heads.
  • both the winding tubes and the paper layers in the region of the guide heads are in some cases subjected to very high loads. This can lead to winding damage, for example, places in the hub.
  • the support roller then carries a major part of the corresponding winding weight and the guide heads take only a residual portion of the weight and from a certain winding roll diameter weight relief forces, if the forces on the line of contact between the winding rollers for the desired winding quality are too large.
  • the material web is introduced in such embodiments from below to the support roller so that the mutually offset winding rollers of both winding lines correspondingly close to the apex line of the support roller and at the same time winding rollers can be made with a very large diameter.
  • the invention is therefore based on the object, a winding device of the type mentioned in such a way that it is universally applicable and even without large and time-consuming conversions a change within the spectrum to be processed on webs and winding sizes is possible.
  • the design effort to solve this task on the winding machine should be low.
  • a winding device for winding material webs in particular fibrous webs in the form of paper, board or tissue webs, comprises a longitudinal cutting device for dividing a material web into individual webs and subsequently arranged winding stations, which wind the individual webs to form a winding reel.

  • the individual winding station each comprises two, preferably transversely to the material web travel direction movable and arranged on both sides of the material web support elements, to each of which a rotatable, retractable on one side of the winding tube guide head is attached.
  • the guide heads bear all or part of the weight of the bobbins when winding. These are either freewheeling or according to a particularly advantageous embodiment for influencing the tension during winding also designed to be driven.
  • Under material web running direction is understood to mean the direction that the direction of passage of the material web in the device in the axial direction considered, that is, the direction between entry and exit in the device. This corresponds to the machine direction, that is, the extension direction of the entire device in the longitudinal direction.
  • material web running direction indicates only the course of the direction. This means that a movement in the web direction of travel includes movements both in the direction of passage and against it.
  • the adjustment of the winding station includes an adjustment of the support elements. These are at least the, the guide heads supporting elements, which may be structurally different.
  • a change in position of the winding station includes a change in position of the wound-up in this winding under displacement of the winding nip.
