Definitions

  • the present invention relates to a winding tube according to the preamble of claim 1.
  • Such cores are used in winders, which are known and described for example in EP 2 048 100.
  • a usually freshly produced, endless plastic film is wound onto a winding tube (a plugged onto the winding shaft sleeve) to a winding of predetermined size. Then the web is cut and the finished roll is preferably replaced by a new flying core flying, so that without delay and possible without loss of material, a new roll can be produced.
  • plastic films are produced in an extraordinary variety of compositions and correspondingly with a wide variety of properties, which then also influence the winding behavior and must be considered accordingly in the winding.
  • the respective production speed and the number of coils to be produced in a production run are parameters which must be taken into account for a qualitatively sufficient production with at the same time reasonable costs.
  • Typical processing speeds range from 2 to 1000 m / min, while the finished wound bales may have a diameter of 50 to 2000 mm and a width of 10 to 6000 mm, respectively.
  • the thicknesses can range from a few ⁇ m down to the millimeter range.
  • films with a thickness of 4 ⁇ to 25 ⁇ can be mentioned. preferably 8 or 15 ⁇ to 25 ⁇ , which are wound at a speed of 100 m / min and a width of about 300 mm to 770 mm on a winding shaft with 4-fold benefit (ie on a winding shaft four cores are plugged and so four reels wrapped parallel next to each other).
  • plastic films made of polyolefins ranges from the mono-extruded film consisting from a single layer, to the co-extruded film with three, five or more layers, wherein, for example, adhesives of all kinds can be provided in the layers, as many different multilayer films arise.
  • the adhesive contained between the plastic layers of the films ensures that the individual windings adhere to one another around the grass bale, so that the winding has stability.
  • the bale of grass is formed, when the film is unwound from the wrapping, a typical, scratching sound is produced which, depending on the adhesive, is louder or quieter.
  • Various farms require quietly releasing films, which has a corresponding influence on the overall recipe of the film.
  • the production varies between the production of only a few identical wound bales for special applications up to the mass production of the same wound bales.
  • the films themselves have different properties, which in turn must be taken into account in the winding for faultless film winding, which special requirements on the winder parameters such as web tension, winding pressure, speed film thickness, and elasticity of the film and stickiness of the film fresh wrap etc.
  • the finished wound film (the winder is usually immediately downstream of the film producing extruder) is still alive, since the various plastic layers still calm and the trapped between the layers of air or introduced substances, often the adhesives, change and also by the Migrate layers. In other words, the production process of the films after winding is not completed yet.
  • the finished rolls must therefore be stored directly following the winding controlled, which often happens at a temperature of 30 to 45 ° C for up to four days.
  • the resulting internal changes in the film have a change in the coil itself result: the winding changes mainly in the roll hardness, which is accompanied by a considerable pressure inside the coil. This pressure is then maintained until the roll for the use of the film is unwound again.
  • a sturdy wrap can be wound on a comparatively thin sleeve as the wrapper will only change a little until it dies.
  • this requires a winding under kgeringem train and low contact pressure, otherwise thin sleeve could be crushed, in which case the sleeve also clamps due to the winding in the stable winding and can not be deducted from this.
  • Such coils are then inevitably very soft and have large air inclusions between the layers, which is undesirable: at the location of the air pockets wrinkles occur in the wound layers, so that the film loses transparency (the developed film is insufficiently transparent at the location of the folds, so that the packaged goods can no longer be seen or writings for identifying the goods can no longer be read there) and whose adhesion is disturbed, since in the winding at the location of the wrinkles under different pressure prevailed and thus locally the properties of the films have changed.
  • the diameter of the wound surface of the winding tube to be wound can be changed, it is possible to remove the winding with its winding tube of the winding shaft and stored with unchanged in the winding winding tube until the winding has died. Then, the diameter of the winding tube can be reduced and these are withdrawn from the winding, which would not be possible due to the pressure prevailing in the inner pressure without reducing the diameter of the winding tube. Due to the fact that the surface of the winding tube to be wound is essentially seamless in the expanded working state and is completely free from the operating pressure.
  • sentlichen uniformly dimensionally stable is supported against the inside, the winding remains during the winding in its inner region without interference, so that it no longer breaks after storage when the sleeve is removed, so he transported accordingly without sleeve to the consumer and in use without Disruption can be completed completely.

  • segment shafts are known in the art and generally have three radially extendable from the winding shaft segments, which increase the diameter of the winding shaft during the winding, so that reduced after winding the diameter by retracting the segments and so deducted the winding of the winding shaft can be.
  • a wound produced in this way shows even after removal from the winding shaft (depending on the recipe of the film) barely recognizable or clearer pressure marks: adjacent segment edges are on the innermost winding layer of the coil, but the rounding of the inner region 2 of the roll 1 in usually not disturbed.

  • the insert 21 extends helically along the length of the secondary sleeve, as shown in the figure. This supports the gentle winding: the film to be wound passes along a surface line on the resulting winding and is pressed there by the winding tension and usually by a pressure roller to the winding.
  • the tendency to form an interference zone with particularly sensitive formulations is due to the different (compared to sheet softer) material in the insert 21 (at least theoretically) still given because there the film could still come into the winding due to the winding tension or the pressure of the pressure roller , In a helical insert this is not the case, since the pressure roller next to the insert on the hard material of the secondary sleeve 20 runs, so can not come into the winding.

Abstract

L'invention concerne un manchon d'enroulement pouvant être emmanché sur un arbre d'enroulement pour l'enroulement d'une bande de matière souple continue en un rouleau (10, 60, 70). Selon l'invention, le manchon d'enroulement présente des moyens pour régler le diamètre de sa surface recevant l'enroulement entre un état de repos à diamètre réduit et un état de travail expansé, et la surface recevant l'enroulement à l'état expansé est configurée sans joints. Il est ainsi possible de supporter un rouleau jusqu'à ce qu'il soit achevé puis de retirer le manchon d'enroulement hors du rouleau et de livrer le rouleau, ce qui rend la circulation des manchons inutile.
