Definitions

  • the invention relates to a corrugated roller for a single-sided corrugated cardboard machine according to the preamble of claim 1.
  • Older single-sided corrugated cardboard machines use so-called fingers, which are thin sheet metal plates that surround the mentioned corrugated roller area of the lower corrugated roller in a crescent-like manner from the outside at axial intervals.
  • the upper corrugating roller is provided with ring grooves in which the fingers engage.
  • Such ring grooves of the upper corrugating roller have the disadvantage that they lead to a corresponding deformation of the surface of the lower corrugating roller. It is therefore necessary to adjust the corrugated rollers axially against each other from time to time in order to even out the wear.
  • More modern single-sided corrugated cardboard machines are so-called fingerless machines.
  • DE-PS 2 840 150 it has become known to arrange a vacuum chamber along the outer circumferential area of the lower corrugating roller which is not covered by the corrugated cardboard web. Via axially spaced ring grooves in the corrugated roller, a negative pressure is also generated in the peripheral region of the lower corrugated roller in which the corrugated cardboard web lies.
  • DE-PS 2 713 464 it has also become known to generate such a vacuum in the ring grooves in that the lower corrugating roller connects an inner one to the vacuum source Has channel which is connected to the annular grooves via radial bores.
  • one of the two corrugated rollers is therefore provided with ring grooves.
  • ring grooves can cause a reduction in the quality of the corrugated cardboard.
  • the corrugated cardboard web to be formed between the corrugated rollers is under considerable tensile stress. The web is therefore deformed into the area of the ring grooves. In this area there is no bonding with the cover sheet afterwards. Furthermore, the stability of the corrugated cardboard is weakened in the direction of the corrugation.
  • corrugated roller with slots are also complex since these have to be milled separately piece by piece.
  • the necessary chrome plating of such a corrugated roller is also complex, since diaphragms have to be introduced into the individual slots in order to omit the slots.
  • the invention has for its object to provide a corrugated roller for a single-sided corrugated cardboard machine, which reduces the impairment of the corrugated cardboard by necessary grooves to a minimum, without influencing the function of the grooves or the corrugated roller.
  • the groove no longer runs perpendicularly to an axis-parallel surface line, as in the prior art, but at an angle not equal to 90 ° thereto.
  • a helical groove is formed. It can also be two or more courses. Another possibility is to provide annular grooves as before, but to arrange them at an angle to the axis of the roller.
  • the ring grooves can also be arranged such that they have opposite inclinations on both sides of the longitudinal center.
  • helical or ring-shaped grooves can also intersect, for example ring grooves crossing each other in pairs can be provided.
  • the advantage of a simple cleaning possibility, as is also given with conventional ring grooves, is maintained.
  • the disadvantages associated with the conventional ring grooves are largely eliminated. Due to the oblique course of the ring grooves relative to the direction of the web, there is, if at all, only a slight deformation of the web in the region of the groove, so that the deterioration in the quality of the corrugated cardboard which had previously been accepted has been eliminated.
  • the production of the corrugated roller according to the invention is no more complex than conventional corrugated rollers with circular ring grooves and less complex than with corrugated rollers with annularly arranged slots.
  • the corrugated roller according to the invention also has increased bending stiffness compared to conventional annular grooves having corrugated rollers.
  • Upper and lower corrugated rollers usually have different numbers of teeth.
  • a groove arranged according to the invention therefore, in contrast to known corrugated rollers, no longer leads to ring-like projections on the corrugated tips opposite the groove due to the lack of abrasion in relation to the grooves, rather the wear of the counter roller is evened out, so that the axial displacement of a corrugated roller from time to time does not occur is more necessary.
  • the effect described results in a longer service life. Above all, the adverse phenomena due to the hump on the ripple tips, which lead to a deterioration in the quality of the corrugated cardboard.
  • the corrugated roller according to the invention is advantageously suitable for all types of corrugated cardboard machines as have become known up to now, i.e. for both finger machines and for fingerless machines.
  • FIGS 1 to 5 show schematically different embodiments for corrugated rollers according to the invention.
  • corrugating roller 10 for example the lower corrugating roller of a fingerless single-sided corrugated cardboard machine, which has a conventional corrugation, but which is not shown for the sake of simplicity.
  • helical grooves 11, 12 extend to the left and right with a predetermined pitch.
  • helical grooves 13, 14 extend on both sides from the longitudinal center, which have the same pitch as the grooves 11, 12, but are offset in the circumferential direction, as in the case of a two-start thread.
  • the shape of the grooves is also not shown, it can be the same as the usual grooves in corrugated rollers.
  • FIG. 2 shows a corrugated roller 20, which has a series of axially uniformly spaced annular grooves 21, which run at an angle unequal to 90 ° to axially parallel surface lines.
  • a first group of annular grooves 31 is provided, the arrangement of which is similar to the grooves 21 according to FIG. 2.
  • a second group of annular grooves 32 are shaped with the opposite inclination as the grooves 31 and arranged so that the grooves 31, 32 intersect at diametrically opposite points.
  • the 4 has a corrugated roller 40 on both sides of the longitudinal center ring grooves 41, 42.
  • the ring grooves 41, 42 have an opposite slope, are otherwise arranged similarly as described in connection with the roller 20 of FIG. 2.
  • the annular grooves according to FIGS. 2 to 4 represent closed loops, which makes cleaning particularly easy with the aid of a cleaning element inserted into the grooves, which performs a reciprocating movement parallel to the axis during the rotation of the corrugating roller.
  • the cleaning element can also move axially parallel during the rotation of the roller. Arrived at one end of the roller, the direction of rotation of the roller must be reversed.
  • a helical course is also conceivable, in which the cleaning element is automatically reversed at one end and moves axially in the opposite direction.
  • Fig. 5 shows two helical grooves 51, 52 in a corrugated roller 50 with opposite but equal pitch.
  • each section of the grooves of the individual corrugating rollers runs at an angle to the direction of the paper web, which also indicates the direction of the pulling force.
  • a shaping of the paper web into the grooves therefore no longer takes place or only to a limited, negligible extent.
