Definitions

  • the invention relates to a hose forming device for forming a hose from at least one material web according to the preamble of claim 1.
  • hose machine In a hose machine according to the DE 44 01 723 are formed from one or more material webs hose sections, in which initially the webs of unwinds wound, perforated and placed one above the other.
  • the material webs are usually made of paper, but also plastic material webs can be inserted. In multilayer webs formed in this way, these layers can be arranged laterally offset.
  • the multi-layered web formed in this way is merged in the further course of the further production process by means of guide devices to form a hose, so that subsequently parts of the side regions of the webs overlap.
  • each layer comes into contact with itself.
  • glue-dispensing devices are provided in hose-forming devices, which generally comprise glue-applying disks.
  • This glue application disc transfers the glue, which is provided in a glue reservoir and applied directly or via suitable transfer means, such as a scoop roller, to the peripheral surface of the glue application disc on at least one side of the side region of the material web to be bonded. If multi-layer webs are to be glued, several glue application disks are usually arranged in parallel in order to be able to provide each layer with a corresponding glue application.
  • glue application disc apparently only comprises such rotating elements, the axial extent of which is smaller than the radial diameter, in the context of this application, rollers or rollers are also to be regarded as glue application discs whose axial extent is greater than the radial diameter.
  • the glue for the longitudinal adhesive seam is removed from the peripheral surface of the glue application disc. This creates on this glue residue at the seam of the circumferential and end face, which hardens during further operation of the machine, the glue, cumulative and thereby forms a wider peripheral surface, which in turn is responsible for a wider glue trace on the longitudinal adhesive seam.
  • the glue line is wider than the overlap region of the webs, so that adhesive edges occur on the finished tube, the further processing of the hose, z.
  • the glue application disc usually had to be cleaned manually, so that the resulting maintenance and labor costs caused a standstill of the machine.
  • the object of the present invention is therefore to reduce the maintenance of the hose forming device and thus to shorten the downtime of the machine.
  • a hose forming device comprising the characterizing features of claim 1. Accordingly, it is provided that at least one end face of the glue application disc comprises on its surface a material to which the glue adheres worse than on the peripheral surface of the glue application disc. It is thus provided that one of, preferably both, end faces of the glue application disc is designed such that the adhesion coefficient for the glue is less than the coefficient of adhesion of the peripheral surface.
  • the glue which is transferred, for example by means of a scoop roller on the glue application disc, only taken from the peripheral surface of the disc and no longer or at least greatly reduced by the end faces and / or the transition areas (seam) between the peripheral surface and end faces.
  • the glue application disc thus carries only as much glue as is removed from the webs to be glued, so that the areas of the glue application disc after contact with the glueing train no longer carries glue. So there are no glue residues that form a germ for a Leimkumulation and thus for a broadened Leimspur.
  • a hose forming device according to the invention therefore no longer needs to be cleaned as often as those of the prior art.
  • the downtime can be shortened and the productivity of the hose forming device can be significantly increased.
  • a glue application disc it is provided to apply such a material after the production of the glue application disc as a coating on the relevant end face of the glue application disc. Due to the separate application of the desired material, a glue application disc can be produced inexpensively, whereby the special properties of the glue used can be taken into account.
  • glues are generally processed water-based, so that in a particularly preferred embodiment of the invention, the material is hydrophobic.
  • Plastic is chosen as the material. Plastics are inexpensive, easy to process and are often characterized by a strong hydrophobicity.
  • the material which is encompassed by the surface of the end face of the glue application disc comprises at least one fluorine-containing material, such as fluoropolymers and / or fluorinated copolymers, preferably polytetrafluoroethylene, which is known as "Teflon".
  • fluorine-containing material such as fluoropolymers and / or fluorinated copolymers, preferably polytetrafluoroethylene, which is known as "Teflon”.
  • Teflon polytetrafluoroethylene
  • the material may comprise a fluoroelastomer.
  • the material may also comprise ceramic materials, which are characterized by a high resistance to a possible mechanical treatment, so that damage to the material can be avoided even during cleaning work.
  • the material comprises a lacquer which can be applied particularly easily to the at least one end face of the glue application disc.
  • the adhesion of the glue is not only influenced by the type of material, but may also depend on the nature, for example the surface properties. Thus, a certain roughness of the surface may cause glue to adhere to this surface particularly badly. For example, it may be advantageous to provide a roughness depth of 1 micron ( ⁇ m) when using plastic materials.
  • Fig.1 a schematic side view of a hose machine for the production of so-called satchel sacks.
  • the apparent from this hose machine consists of, for example, three unwinding points not shown, in which successively arranged paper rolls 1,2,3 are held, of which flat paper webs 4,5,6 are withdrawn via guide rollers and unwinding and / or deduction facilities.
  • three perforating cylinders 8, 9, 10, preferably provided with their own drives, are mounted in a perforating station, their perforating knives 11 cooperating with counterblade cylinders 8 ', 9', 10 '.
  • the transverse adhesive strips provided the paper webs 5 and 6 with transverse adhesive orders.
  • the transverse adhesive strips 14 of the transverse adhesive cylinders 12, 13 receive their adhesive jobs in the usual way of adhesive application rollers.
  • the paper webs 4, 5, 6 are brought together for their bonding to form a multilayer web.
  • An edge region of the web, on which the individual webs are laterally offset from one another, is provided with a glue application 16 which forms the subsequent longitudinal seam by means of a glue applicator disk 16 which is provided with recesses 17 which ensure that they are provided with transverse perforations Edge regions of the multilayer paper web are not provided with adhesive jobs.
  • the longitudinal adhesive segments lying between the recesses 17 and the longitudinal adhesive segment of the longitudinal adhesive rollers receive their adhesive applications in the usual way from an adhesive application roller or scoop roller, not shown. Since the individual layers are offset laterally, it may be provided to use a plurality of glue application disks 16 arranged parallel to one another.
  • the prepared in the manner described, multi-layer paper web is then folded in a tube forming device 18 to form a tube, wherein the respective overlap-free edge regions of the individual layers stick together.
  • the bonding takes place, as already described, via a longitudinal adhesive roller or a plurality of longitudinal adhesive rollers 16.
  • the tear-off station 19 the individual tube sections 20 are then torn off the paper tube.
  • the tear-off station is standard Abrmonywerk provided, which consists of two rollers driven at different peripheral speed, of which the front forms a holding roller and the rear a tear-off roller, wherein in time with the tearing of the individual sections 20 by a cammed roller 21 in a movable support mounted counter-rollers to the Holding and Abr constituwalzen be pressed.
  • Fig.2 the glue application device is shown separately.
  • the scoop roller 23 removes adhesive from the glue trough 25.
  • the amount of the adhesive can be adjusted by means of a metering roller 24, which can be moved relative to the scoop roller 23 for this purpose.
  • the adhesive transferred from the scoop roller 23 to the glue application disc 16 is applied by the latter to the merged edge regions of the pulp webs.
  • the recesses 17 in the glue application disc 16 serve to keep the perforations, for the production of individual tube sections, free of adhesive.
  • doctor blades which may be provided, for example, to remove laterally adhering to the glue applicator glue.
  • doctor blades can solve the above-mentioned problem, but lead to wear of the doctor blade and / or glue application disc and thus do not convincingly solve the problem. Further doctor blades may be provided to limit the thickness of the glue layer on the peripheral surface of the glue application disc.
  • the Fig. 3 again shows the glue application roller 16 in a perspective view, in which the peripheral surface 27 and one of the two end faces 26 can be seen.
  • the end surface may comprise a material to which the glue adheres worse than on the peripheral surface 27. This material may be limited to an annular surface 28 which directly adjacent to the peripheral surface 27 (see Fig. 4 ).
