Definitions

  • the invention relates to a method according to the preamble of claim 1. Furthermore, the invention relates to a device according to the preamble of claim. 4
  • the invention has for its object to provide a method with which a precise adjustment of the basis weight of the resting on the conveyor belt and flattened by the scalpel bulk material is feasible with extended bulk material density limits in front of the roller.
  • the upper limit of the bulk density is increased before the scalpel.
  • the bulk material web 2 is transported by the conveyor belt 4 in the direction of the arrow P1 at feed speed.
  • Profil matterss institute 3 Beispie pressure rollers, which are each driven at feed speed, compressively deformed.
  • These Profil textss institute are, each by itself, in the direction of the double arrow P2 by actuators 5 movable up and down according to the determined basis weight distribution in front of the Scalperwalze in adaptation to the desired basis weight distribution after the Scalperwalze in height to the calculated for each section 2a measure Y2 positioned.
  • Profiling elements 4a which lift the conveyor belt 4 from below against the pressure forces of the upper profiling elements, are provided in the projection of these profiling elements 3 acting from above. These profiling elements 4a are individually in height in the direction of Double arrow P3 movable and are positioned according to the desired basis weight distribution on the calculated mass Y1.
  • profiled elements 4a designed here as runners extend at least as far as the middle of the scalpel roll, in order to avoid deformation of the adjusted bulk material web profile before leveling.
  • the finally leveled by the Scalperwalze bulk material web has after these operations over the entire width on the same basis weight.
  • any basis weight profile can also be set.
  • the distribution of the basis weight of the scattered bulk material over the width of the bulk material web is determined in a known manner by means of the X-ray line 6 and from this average density values ⁇ 0 are formed for each section 2a in the projection of the profiling elements.
  • the device is provided according to the invention to compress the bulk material web in areas of low basis weight by profiling elements from above, before their top is eroded by the Scalperwalze no matter.
  • the bulk material web 5 is transported by the conveyor belt 6 in the direction of the arrow P1 at feed speed.
  • the drive roller 1 is synchronously height adjustable with the Scalperwalze.
  • the speed of the drive roller can be synchronized with the bulk material feed with an adjustable lead - to avoid impoundments.
  • each a jawnverstellsupport 9 and a Positionieraktor 10 form a functional group 11.
  • These groups of functions are attached in the example of the suction hood 7a of the Salperwalze.
  • the pressure rollers 2 are each divided into two partial pressure rollers 2a and 2b. This corresponds to the division of the friction wheels 4 in two partial friction wheels 4a and 4b.
  • the pressure-medium-loaded cylinders 8 are double-acting.
  • the cylinder stroke is dimensioned so that when completely retracted piston, the friction wheel 4 is released from the drive roller and can be swung up for replacement work.
