Definitions

  • the invention relates to a corrugating roll, in particular for corrugated cardboard plants, and a process for their preparation.
  • the invention is based on the object, a corrugating roller and a method to provide for their preparation, which is designed such that the Insertion of a paper web into the contact area between two corrugating rolls as evenly as possible.
  • the basic structure of a machine for the production of corrugated cardboard is out DE 100 34 780 A1 (corresponding to US Ser. No. 09/667 713), there in particular Figure 1, known, to which reference is hereby made.
  • the machine for production of corrugated cardboard has a lower corrugating roll 1 and an upper Corrugating roll 2 on.
  • the corrugating rolls 1 and 2 have projecting at their ends Shafts 3 and 4 with associated, mutually parallel axes of rotation 5 or 6 on. On their cylinder surfaces, they are parallel with each other provided to the axes 5, 6 extending corrugations 7 and 8, respectively, in a Touch area 9 with each other.
  • the upper corrugating roller 2 is driven in a rotational direction 10 by a drive 11 while the lower corrugating roll 1 is taken in a rotational direction 12.
  • the contact area 9 enters a paper web 13, which passes through the corrugations 7, 8 is formed into a corrugated web 14.
  • turning direction 10 resp. 12 downstream of the contact region 9 is one in DE 100 34 780 A1 (according to US Ser.No. 09/667 713) more closely described Leim concludedsEinraum for gluing the tips of the corrugated web 14 and also a Pressing device for pressing a laminating against the glued Corrugated web 14 is provided.
  • the corrugating rolls 1 and 2 are, as known for example from DE 100 34 780 A1, Figure 2, pressed against each other to produce a predetermined line contact pressure, which should be as uniform as possible over the width of the corrugating roll in the contact region 9.
  • a givenmilinanpresskraft by pressing together the bearings of the shafts 3 and 4 can not be achieved due to the dead weight and the resulting deflection. It therefore equips at least one of the two corrugating rolls 1, 2, in the present case, the lower corrugating roll 1, with a so-called camber. This means that the diameter of the corrugating roll 1 increases continuously from the two ends to the middle.
  • corrugations 7 and 8 have an ideal course shown in Figure 5 in more detail.
  • Each corrugation 7, 8 has a radially projecting corrugation head 15, which has a predetermined, constant curvature with radius of curvature R K shown in cross section in Figure 5.
  • the curvature of the corrugated head 15 is convex relative to the axes of rotation 5 and 6, respectively.
  • the corrugated head 15 has a ridge line 16.
  • Each corrugation head 15 is mirror-symmetrical with respect to a plane passing through the comb line 16 and the axes of rotation 5 and 6 perpendicularly intersecting plane of symmetry.
  • Each corrugated head 15 is bounded on both sides by a substantially straight flank 17 which extends approximately from the end of the upper quarter of the height H of the corrugation to the beginning of the lower quarter of H.
  • Each of the flanks 17 is adjoined by a concave corrugated foot 18 in relation to the axes of rotation 5 and 6, respectively.
  • the corrugated foot 18 has a predetermined, constant curvature with radius of curvature R F.
  • the radius of curvature R K is smaller than the radius of curvature R F.
  • the difference of R F and R K depends on the paper thickness, the type of paper and other parameters and is often between 0.1 and 0.8 mm, in particular between 0.28 mm and 0.51 mm.
  • the corrugations 7, 8 extend parallel to each other across the width of the corrugating rolls 1 and 2 parallel to their axes of rotation 5 and 6. Further, the corrugations 7, 8 are uniformly distributed over the circumference of the lateral surfaces of the corrugating rolls 1 and 2 respectively.
  • the spacing of adjacent corrugated heads 15 is referred to as pitch T.
  • Each division T is associated with a pitch angle ⁇ T , the adjacent corrugated heads 15 with respect to the respective axis of rotation 5 and 6 include.
  • the pitch angle ⁇ T is constant in each case, wherein the pitch angle of the corrugating roll 1 need not be the same pitch angle of the corrugating roll 2.
  • the structure of the corrugations 7, 8 shown in Figure 5 corresponds to the ideal course in a cylindrical roller without camber.
  • FIG. 6 shows the cross-section through the center of a prior art corrugated corrugating roll.
  • the reference numerals in FIG. 6 merely serve to identify parts of the same function in comparison with the machine according to the invention for the production of corrugated cardboard described with reference to FIGS. 1 to 5.
  • Figure 6 shows a corrugating roll according to the prior art
  • the same reference numerals are used in Figure 6 for the functionally identical parts, as in the embodiment according to the invention with a raised line.
  • the solid line in FIG. 6 at the upper end of the corrugating roll 1 ' shows the actual outer contour of the corrugations 7' in the region of the center of the corrugated roll 1 'provided with a camber.
  • the dashed line shows the ideal course 20 'of the corrugations according to FIG. 5.
  • the corrugated feet 18' also correspond in the center of the corrugating roll 1 ', ie the region of maximum diameter, to the ideal course according to FIG. 5.
  • the corrugated heads 15' are too broad, as the projection opposite the dashed line of the ideal course 20 'shows. This is due to the prior art sliding method. In the prior art, a rotating grinding wheel is used with a radially projecting annular bead whose outer contour corresponds to the contour of the ground to be ground rifling foot 18 '.
  • the pitch T ' ie the distance between adjacent ridge lines 16', is thus greater in the region of the center of the corrugated roll 1 'provided with a camber than at the two edge regions. This is the cause of the widening of the corrugated heads 15 'in the prior art grinding method. Since the corrugation heads of the lower corrugating roll do not fit exactly to the corrugation heads of the upper corrugating roll over the entire width of the corrugating roll, this leads to an uneven feeding behavior of the paper web 13 'into the draw-in region 19' and thus to a wrinkling which reduces the quality the corrugated cardboard produced deteriorated permanently.

  • the grinding wheel 27 has two in with respect to the shaft 26 radially projecting, parallel to each other Ring beads 33, 34, between which a relative to this radially recessed annular recess 35 is provided.
  • the annular beads 33 and 34 are based on the circumferential line maximum distance of the shaft 26 from the recess 35 facing halves 36 and this turned away halves 37.
  • the recess 35 together with the adjacent halves 36 corresponds exactly to the negative contour of a in FIG 5 illustrated ideal ripples 7, 8, d. H. a corrugated head 15, the two illustrated ideal ripples 7, 8, d. H. a corrugated head 15, the two adjacent flanks 17 and in each case a half riffel foot 18.
  • the Both outer halves 37 of the grinding wheel 27 are each in outer cylindrical sections 38, whose distance from the shaft 26 as well is large, or preferably slightly smaller, than the distance of the deepest Point 39 of the recess 35.
  • the outer contour of the half 37 is in Compared to the outer contour of the half 36 slightly narrower, so the two Halves 36 and 37 with respect to the center line 40 is not mirror-symmetrical are.
  • a corrugating roll blank 41 is clamped in the bearing blocks 31.
  • the blank 41 may have a camber.
  • the rotating grinding wheel 27 is lowered onto the blank 41 and displaced along a longitudinal direction 43 extending parallel to the central longitudinal axis 44 of the blank 41 on the blank 41. If the blank 41 has a camber, the grinding wheel 27 in the guide 29 is displaced upward.
