Definitions

  • the invention relates to a machine for producing a corrugated cardboard web laminated at least on one side.
  • the invention is therefore based on the object, a machine of the generic type in such a way that the quality of the corrugated cardboard web produced over the service life is not affected.
  • This object is achieved by the features in the characterizing part of claim 1. It has been shown that a delay of the pressure belt during operation is effectively prevented by the firm connection between weft threads and warp threads, so that the quality of the corrugated cardboard web produced is reliably maintained over a long period of operation.
  • the measures according to the invention can be applied both to fabrics according to claim 5 and to claim 6.
  • a lower corrugating roll 2 and an upper corrugating roll 3 are rotatably supported by means of shafts 4, 5. They have mutually parallel axes 6, 7. At their cylindrical surfaces they are provided with parallel to the axes 6, 7 extending corrugations 8, 9, which mesh with each other in the contact region 10 of the two corrugating rolls 2, 3.
  • One of the corrugating rolls 2, 3, usually the upper corrugating roll 3, is driven in the direction of rotation 12, while the other corrugating roll, usually the lower corrugating roll 2, is taken along by the other corrugating roll 3 in the direction of rotation 11.
  • a glue applicator 13 is arranged in the machine frame 1, which has a glue applicator roll 14, which is deliverable against the corrugation 9 of the upper corrugating roll 3.
  • the applicator roll 14 is rotatable about an axis 15.
  • a pressing device 16 which has a deflecting roll 17, a tensioning roll 18 and a pressing belt 19.
  • the guide roller 17 and the tension roller 18 are rotatably supported respectively by means of shaft journals 20 and 21 in bearings 22 and 23 of the machine frame 1 about an axis 24 and 25, respectively not driven. All axes 6, 7, 15, 24, 25 run parallel to one another.
  • Embodiments for the tension roller 18 are well known, for example from the DE 44 20 726 A (corresponding U.S. Patent 5,632,850 ).
  • a tensioning of the pressure belt 19 takes place by displacement of the tensioning roller 18 parallel to the outlet tangent 27 in the direction 28.
  • the pressure belt 19 is about a wrap angle g of about 90 ° against the corrugation 9 of the upper corrugating roller 3 and runs in the same direction with this according to the directional arrow 26.
  • the pressure belt 19 runs from the upper corrugating roller 3 in accordance with theticiantangente 27, which is identical to the inlet tangent of the Anpressbandes 19 on the tension roller 18.
  • the pressure belt 19 is formed as a fine-mesh, tensile sieve-belt, as a fabric, as shown in detail in Figures 2 to 5. It consists of warp yarn 30 extending in its longitudinal direction 29 corresponding to the directional arrow 26 and weft yarns 31 running transversely thereto.
  • the warp yarns 30 are each provided in pairs of three warp yarns 30a, 30b, 30c, these pairs of warp yarns 30a, 30b, 30c having a width a greater than the distance b of adjacent pairs of warp yarns.
  • the two outer warp threads 30a, 30c of each pair of warp threads run in the same direction, ie they are each guided over the same side of a weft thread 31, while the middle warp thread 30b is guided in opposite directions, in particular Figs. 2 to 4 can be removed.
  • the three warp threads 30a, 30b, 30c are provided and guided in this manner per pair of warp threads 30a, 30b, 30c, a symmetrical clamping of the respective weft thread 31 is achieved.
  • each warp thread 30a to 30c consists of six strands 32 which are twisted together, that is, twisted.
  • the diameter c of each strand 32 is in the range of 0.2 mm. If appropriate, the diameter c of the strands 32 can also be less than 0.2 mm to reduce wear, namely in the range from 0.15 to 0.2 mm. As a result, the diameter d of each warp thread 30a to 30c is in the range of 0.6 mm.
  • the strands 32 each consist of steel wire. Due to the stranding, the individual warp threads 30a to 30c on the one hand very tensile and on the other hand very flexible. For the ratio of the distance b of the pairs of warp threads 30a to 30c to the diameter d of the individual warp threads 30a, 30b, 30c: 1.2 d ⁇ a ⁇ 0.3 d.
  • the weft threads 31 are made of a material which is softer than the material of the warp threads 30a to 30c, so that the warp threads 30a to 30c dig into the weft threads 31 to form slight notches 33, as it were in the latter.
  • the free ends 34 of the weft threads 31 are spherical cap-shaped, ie rounded, to eliminate the risk of injury.
  • the weft threads 31 are made of rod-like wires whose diameter e is in the range of 1.0 mm.
  • the distance f of adjacent weft threads 31 is in the range of 1.0 to 1.5 mm and preferably in the range of 1.1 to 1.2 mm.
  • the pressure belt 19 is made of a finite metal-fabric band, the ends of which are connected in the region of a weft thread 31 in the usual manner according to the prior art, for example by a solder joint or a weld eyelet connector.
  • the warp threads 30 and the weft threads 31 are connected to each other at the intersections by means of suitable plastic, wherein the connection points 35 are shown in black in FIGS. 2 to 4.
  • the dimensional stability of the pressure belt 19 is greatly increased, d. H. a slipping of the warp threads 30 relative to the weft threads 31 in the longitudinal direction can no longer take place. This is also a delay or the occurrence of constrictions of the Anpressbandes 19 excluded.
  • the preparation of the compound only at the intersections or the junctions 35 at the intersection occurs in such a way that the pressure belt 19 is immersed in a suitable liquid plastic, which drips after removal from the plastic bath, so that only at the junctions 35 plastic remains and sets or hardens.
  • a laminating 39 is supplied, which also consists of paper and has the same width as the paper web 36. This laminating 39 is inserted against the outer side 40 of the Anpressbandes 19 and in the defined by the wrap angle g pressing portion 41 of the pressing belt 19th pressed against the tips 38 of the corrugation 9 of the upper corrugating roll 3 lying, corrugated paper web 36 and connected thereto.
  • the pressing belt 19 in this case presses with its outer side 40 the laminating sheet 39 against the corrugated paper web 36.
  • the upper corrugating roller 3 is heated in a conventional manner, for example to about 170 ° C, evaporates contained in the tips 38 of the corrugation 37 glue 42 contained water and escapes at least partially through the liner 39 and the screen-like pressure belt 19th
  • the ready-glued, one-sided laminated with a liner 39 corrugated board 43 runs in the direction of the Jardintangente 27 together with the pressure belt 19 from the upper corrugating roll 3 and is performed with the pressure belt 19 partially around the tension roller 18 around. From there it is fed in stripping 44 a winding device.
  • the heating of the paper webs 36, 39 does not have to take place via the corrugating roller 3. It can alternatively or optionally also by a within the Anpressbandes 19 between guide roller 17 and tension roller 18 arranged in Fig. 1 by dashed lines indicated heater 45 are made.
  • the dimensional stability of the pressing belt 19 ' can also be achieved by providing it with a coating 46 of a suitable plastic on one side of the weft threads 31.
  • This coating 46 substantially enveloping the warp threads 30 on the corresponding side is applied to the outside 40, so that this side abuts against the paper web 36.
  • this coating 46 works dirt-repellent d. H. Fibers and the like from the paper web 36, the pressing belt 19 'no longer pollute.
  • a coating 47 can also be applied to the pressure belt 19 "which completely covers the fabric comprising warp threads 30 and weft threads 31 on both sides.
  • the fabric itself may also be dense, that is to say with closely aligned warp threads 30.
  • the type of coating is the same as previously described.
  • the representation in FIGS. 11, 12, 13 corresponds to that in FIGS. 2 to 4
  • the representation in FIGS. 14, 15, 16 corresponds to the representation in FIGS. 6 to 8
  • the illustration in FIG. 17 18 corresponds to that in FIGS. 9, 10.
  • Suitable plastics for the coatings 46 or 47 is PU (polyurethane), in the form of an elastomeric 2-component adhesive. Furthermore, this PTFE-like materials, ie polytetrafluoroethylene in elastomeric modification into consideration.
  • the one-sided coating 46 may further be made by knife coating, i. H. by applying the plastic in liquid form by means of an applicator roll, on which the liquid plastic is brought into a predetermined layer thickness by means of a doctor blade.
  • the one-sided coating 46 and the double-sided coating 47 can furthermore be effected by pressing on foils.
  • the plastic can also be applied in the form of a paste, in which case the crosslinking takes place under heating in an oven.
