Definitions

  • the invention relates to a tube strand made of a continuous, helically wound web of paper, cardboard or similar material, edge regions of the web overlapping one another and being firmly connected to one another to form the tube strand wall, and a method for producing a continuous web from a continuously running web made of paper, cardboard or similar material helically coiled tubing.
  • similar material refers to materials that are suitable as substitute materials for paper or cardboard in terms of their nature, behavior and / or use, e.g. Plastic-laminated papers or cardboards, laminated papers or cardboards, textile plastic laminates or combinations of such materials, which are subject to restoring forces during the deformation, i.e. tend to return to their original shape.
  • the invention has for its object to provide a pipe string of the type described above, which has a high strength with low weight, and at the same time to propose a method of the type also described above, with which such pipe strings can be produced in a cost-effective manner.
  • the object on which the invention is based is achieved in the case of a tubular string in that the web is formed over at least part of its width with a plurality of parallel shafts which are aligned with their main extent in the longitudinal direction of the web and the helical coil.
  • the object is achieved in that the web is deformed over at least part of its width to form waves extending in its longitudinal and downward directions and is joined to the pipe string wall with partial overlap and connection of its side edges.
  • a part of the two waves in relation to the width of the outside of the parts of the paper web which are adjacent to one another in the overlap area should and can contact each other in the flank area and be connected to one another there.
  • at least one of the shafts lies side by side in the overlapping area Parts of the web are in engagement with at least one shaft of the adjacent part of the web. It can be left open which part of the web width the waves occupy.
  • the shafts can also be arranged over the entire web width, in which case at least the two outer shafts of adjacent web parts should overlap one another in order to fulfill the aforementioned purpose.
  • the web has an undulated side strip on at least one side of the waves, which covers at least part of the waves of the adjacent web part and is connected to the covered wave heads.
  • This non-corrugated side strip not only serves as a smooth lamination of the shafts, but also acts as a load-bearing element with regard to their dimensional stability and prevents the shafts from being smoothed due to the restoring forces of the material.
  • the intermediate Wandun sstar g is formed by the corrugated material and thus constitutes the strength-determining part of the tube Stanges.
  • the outer shafts should also advantageously mesh with one another in order to achieve sufficient "toothing" in the edge region.
  • the web is preferably at least in the area of the shafts with a material-stiffening application made of wax, a thin plastic film or the like. coated or soaked.
  • a material-stiffening application made of wax, a thin plastic film or the like. coated or soaked.
  • the web can at least in the area of the Parts forming the inner wall of the tubing string, such as shafts and / or inner overlap, are provided with a knurling which extends essentially transversely to the longitudinal direction of the paper web. So the compression is better absorbed; they compensate for the opposing forces that occur in the outside area.
  • the pipe string wall can be formed from at least two superimposed, helically wound and provided with shafts running in the longitudinal direction of the helix.
  • the web can be pre-deformed at least over part of its width substantially transversely to its longitudinal direction, e.g. be knurled. This is done, for example, with finely corrugated roller rollers.
  • the shafts are preferably produced by pushing the web together transversely to its longitudinal extent, in a particularly preferred manner step by step, in order to keep the forces exerted on the material during the wave formation within manageable limits.
  • the wave formation can take place gradually symmetrically, starting in the middle of the path, but it is also possible to make it asymmetrical, e.g. starting from one side.
  • the web can immediately or at least in the area of the waves with a stiffening material such as wax, solidifying liquid plastic or the like after the wave formation. soaked, coated or provided in a similar manner.
  • a stiffening material such as wax, solidifying liquid plastic or the like
  • the procedure is such that the web is at least partially provided with adhesive in these overlap areas before the helical winding, in particular on the heads of the overlapping or overlapping shafts, and glued.
  • Such a connection is procedurally simple to manufacture and can be integrated into the overall sequence of the manufacturing process.
  • the waves can be formed over part of the web width in such a way that either a smooth side strip remains on one of the two sides of the web, which extends over or under the entire wave width of the adjacent web part, or that in each case to both One smooth side strip remains on each side of the web, in which case one of the side strips engages under its adjacent part of the web and the other Side stripes overlaps its neighboring web part. So you get either a single-layer or a double-layer smooth covering of the shafts. For a firm, shape-retaining connection, the shafts in the area of their heads and at appropriate and respectively suitable places on the smooth side strips are coated with adhesive such as glue and glued to the adjacent web parts overlapping them.
  • the procedure is advantageously such that at least two webs are wound one above the other and connected to one another after the waves have been formed.
  • the pipe string wall can advantageously be covered on its inside and / or outside with a smooth paper or film web.
  • the illustrated exemplary embodiments all relate to the use of paper as a material web, although, as stated, other suitable materials which are equivalent or similar to paper in terms of their nature, their behavior and / or their possible uses are also suitable.
  • Fig. 1 shows a pipe string 10 produced according to the invention, each with a smooth inner and outer wall, which is produced by helically winding a continuous paper web 2, whereby adjacent paper web parts a, b, c, d, e ... arise.
  • This paper web 2 is provided with waves 3 at least over part of its width in a device suitable for this purpose, the height of which essentially determines the thickness of the raw strand wall.
  • the shafts 3 are expediently produced by pushing the paper web together, at least the corrugated paper web part then remaining until the paper web is joined, in order to avoid regression due to the restoring forces of the paper.
  • the construction of the tubing string 10 goes in detail from Fi g. 2 and 3.
  • the paper web is formed over a part of its width with waves 3, six in the example shown, by gradually pushing them together.
  • This corrugation area is designated 23, its width in Fi g. 2 recognizable.
  • the width of these side strips can also be seen in FIG. 2.
  • both side strips 21 and 22 are selected to have the same width, but they can also have different widths.
  • the total width of the paper web is thus composed of the two side strips 21 and 22 and the wave area 23 after the waves 3 have been attached and is likewise indicated in FIG. 2.
  • the configuration of the shaft region 23 is to be selected such that one of the side strips, in the present case the right side strip 21, above, and the other side strip, in the example shown, the side strip 22 comes to lie below. It is thereby achieved that the two side strips 21 and 22 overlap or underlap the respectively adjacent paper web part and cover the undulating region 23 thereof.
  • a wave area 23d is closed on the right by a wave area 23d and on the left by a wave area 23b by nestling the last wave in each case. In this area of contact or nestling of the flanks, gluing should advantageously also take place.
  • the wave region 23c is completely covered on one side by the top side strip 21b of the left adjacent paper web part b and on the other side by the bottom side strip 22d of the right adjacent paper web part d.
  • the side strip 21b covering the wave region 23c is still partially covered by the next side strip 21a of the paper web part a to the left of it, while in turn covering the it overlaps the right side strip 21c adjacent to it. Bonding also takes place in these overlapping areas.
  • the pitch of the helical coil is indicated.
  • a substantial part of the paper web width thus serves to cover the shaft area 23, so that in this embodiment there is a closed, smooth inner and outer wall.
  • the inner wall is determined by the side strips 21 at the top, the outer wall by the side strips 22 at the bottom.
  • FIGS. 4 and 5 essentially has the same structure as the example of FIGS. 2 and 3, in particular with regard to the side strips 21 and 22 covering the wave regions 23; the only difference is that in Fig. 4 and 5 the waves of adjacent paper web parts partially interlock, namely here a pair of waves 3b, c. This results in an even firmer and more durable possibility of connecting adjacent paper web parts a, b, c, d.
  • Fig. 6 shows a pipe string 11 which has a smooth inner wall and a corrugated outer contour. Details of this tubing string 11 can be seen in the detailed representation of FIGS. 7 and 8. As can be seen, only one side strip 21 lying at the top is provided in this embodiment, while the wave region 23 is formed up to the other edge of the paper web 2. Interlocking in the edge area is only provided for one shaft, as can be seen in particular from FIG. 8.
  • the inner wall of the pipe string 10 is determined by the side strips 21a, 21b, 21c, which in part overlap twice.
  • the outer contour results from the waves 23b, 23c, 23d. In this embodiment, gluing can therefore only take place in the area of the inner wall and the overlapping wave areas.
  • Such pipe strands can be used when certain deformations of the outer contour can be accepted or may even be intended.
  • FIGS. 10 and 11 shows a pipe string 12 with a smooth outer wall and a corrugated inner wall structure.
  • FIGS. 10 and 11 there is a practically only 180 rotated arrangement compared to the embodiment of FIGS. 7 and 8, wherein instead of the side strips 21 shown there above, undulating side strips 22 underneath here undulate the wave areas 23 cover and wear on the outside.
  • This embodiment is, for example, in such cases advantageous applicatio g s in which a deformation of the internal structure is desirable to be able to compensate for example for bottle packaging or tube sheets to some variations in diameter of the coated parts.
  • Fig. 12 shows an embodiment in which a tubing string 13 is made of double-layer paper web material.
  • Such multilayer pipe strands have a very high strength of their walls and are accordingly highly pressure-resistant and secured against bending.
  • FIG. 13 shows an embodiment% of the tubular string without smooth side strips, ie with corrugations formed over the entire width of the paper web.
  • the waves of adjacent paper web parts g mesh with one another in a more or less large number, depending on the intended use, and thus form the interlocking connection. Since in such exclusively corrugated webs it is imperative to reset the waves due to the nature of the material, the paper web must in any case be provided with a material application which ensures dimensional stability.
  • FIG. 14 shows a preparation stage for the paper web, here designated with its total width 2, in two variants.
  • This preparation takes place before the generation of the wave profiles and consists in that the paper web 2 is knurled over part of its width or over the entire width.
  • Such curling consists in a very tight gathering of the paper in order to be able to compensate for the differences in the forces occurring on the inner wall and outer wall during the later winding into helical coils.
  • Such curling creates target compression points. They are required in the area of the inner parts of the paper web in the finished tubing string, since the highest compression forces occur here, while tensile forces can be absorbed in the outer area to the extent of the tensile strength of the paper material used, but without the paper being subject to stretching.
  • the curling is also possible to design the curling as a curl 42 covering the entire paper web width 2, since a desired compression in the area of the outer side strip 22 has hardly any disadvantages.
  • the choice between the knurls 41 and 42 essentially depends on the tools available.
  • the principle of wave profile formation is also indicated in FIG. 14.
  • the paper web 2 is pushed together transversely to its longitudinal direction, that is to say in the direction of the arrows A, so that waves running in the longitudinal direction of the paper web arise in the region 23. Since the paper web runs lengthways through the machine, the waves can only be generated in stages, i.e. it is not possible to generate all the waves taking up the wave width 23 at the same time, but this must be done in succession in order to be able to control the pull-in forces in a reasonable manner.
  • the wave profile is formed using tools designed according to the waveform, e.g. in the form of rollers that carry such a profile on their circumference.
  • these profiling tools do not form the subject of the present application and therefore do not need to be explained in more detail here.
  • An example of such tools can be found in BE-PS 748 937, although they are used there to deform aluminum in the manufacture of corrugated aluminum tubes.
