Definitions

  • the invention relates to a winding machine for winding, possibly longitudinally divided webs, preferably paper webs, with the features of the preamble of claim 1.
  • the winding bed is formed exclusively from the two support rollers,
  • the second support roller in the web running direction has a jacket which is much more deformable than the jacket of the first support roller in the web running direction
  • the second support roller in the web running direction is lowered compared to the first support roller in the web running direction, so that a plane through the axes of the two support rollers forms an angle with the horizontal.
  • the object of the invention is to improve a generic winding machine in such a way that the winding quality is further optimized even with large weights.
  • the invention has for the first time recognized that the dynamic load on the roller during winding must be taken into account when determining the elasticity or rigidity of the surface of the roller. It has been shown that the total load resulting from dynamic and static loading of the incoming web partially entwined, d. H. in the web running direction of the first carrier roller is generally relatively higher than that of the other carrier roller (claim 2).
  • a further significant improvement in the winding result can be achieved in that the second support roller in the web running direction has a relatively higher coefficient of friction in the area of its surface touched by the web than the corresponding surface of the first support roller in the web running direction.
  • the degree of tensioning or unloading of the paper web on the outer roller surface can hereby be set or specified in an optimal manner.
  • Such an embodiment is particularly preferred in which the weight load of the second support roller in the web running direction is particularly small compared to the weight load of the first support roller in the web travel direction.
  • the invention has recognized that this gap can only be obtained uniformly if the web to be wound is sufficiently porous to allow the compressed air to pass through. In most cases, irregularities in the surface of the roll that has already been wound along the line of contact with the wrapped support roller have an extremely negative effect on the amount of pressure relief air drawn in.
  • the resilience of the sheathing of the support roller, which is wrapped by the supplied web means that the roller surface adapts along the line of contact with the already wound roll to the undulation of the roll in this contact line. In this way, possible air intake gaps between the drawn web and the wound one Roll minimized and thus the intake air reduced to a tolerable amount. It goes without saying that the combination according to the invention of an airlift with a resilient sheathing of the wrapped support roller can also be used very advantageously if the non-wrapped (second) support roller has a hard sheath instead of a resilient one.
  • Fig. 2 shows another embodiment of the winding machine, also in front view and
  • Fig shows a support roller according to the invention with a partially wound roll in a side view (all figures highly schematic).
  • two drive rollers TW1 and TW2 of the same diameter are provided, both of which have an elastically deformable casing M1, M2, the casing M1 being the relatively "softer” and the casing M2 being the relatively " forms harder "base.
  • the supplied paper web PB wraps around the first support roller TW1 approximately 180 ° and is wound into the roll R with the roll weight G.
  • the weight load on the two support rollers can be artificially increased by a loading roller, as is known per se (GBLW).
  • the normal load N1 and N2 exerted by the roller weight on the two support rollers is the same in this exemplary embodiment.
  • the dynamic load on the wrapped roller TW1 and thus the total load on this roller is higher than that of the roller TW2.
  • a housing, referred to as AL, of an air lift known per se is inserted from below essentially edge-sealingly into the lower gusset area between the two support rollers.
  • compressed air which is fed to the airlift housing in a manner not shown, can flow through the spacing gap between the two support rollers into the space above it, which is sealed off by the roller R, as weight relief compressed air, the end faces of this pressure relief space DR are sealed in a known manner.
  • the embodiment according to FIG. 2 differs from that according to FIG. 1 inter alia in that the diameter of the wrapped support roller TW1 is larger than the diameter of the support roller TW2 and the axis of the latter is higher than that of the former, whereby the load roller is effective at an angle to the vertical.
  • the Normal load Nl of the support roller TWl noticeably greater than the normal load N2 of the support roller TW2.
  • the surface of the non-wrapped support roller TW2 is provided with a coating RB which increases its coefficient of friction. An airlift is only an option and is therefore shown in dashed lines.
  • FIG. 3 illustrates how the strongly exaggerated waviness of the wound roll R is simulated by the elastically deformable jacket M1 of the support roller TW1 and thus air intake gaps are minimized or suppressed.
