Definitions

  • the known methods and devices have the disadvantage that the distribution of the powdery material to be sintered will not be perfectly uniform on the base.
  • any uneven distribution has the eiiect, that, after rolling, surfaces of unequal thickness will result.
  • the applying device comprises afiexible and very thin conveying band which has a thickness of the order of magnitude of about 0.1 mm. and with which the powdery substances are deposited on the base.
  • This conveying band may consist of a synthetic material of very high tensile strength or of a woven fabric of nylon or Perlon.
  • a further feature of the invention consists in this, that the very thin conveying band is taken round a roller of very small diameter at the feeding place or round a slightly rounded edge in such a manner that the depositing of the conveyed material will not be substantially influenced by a curvature at the place of deflection.
  • the feeding of the conveying band with powdery material takes place by way of a supply hopper which is provided above the conveying band with an adjustable gap for the passage of the powdery material.
  • the gap can be adjusted for instance by the displacement of a hopper wall.
  • the supply of the powdertakes place inthe upper part.
  • the means for supplying the powdery material to the hopper may be displaceable, such that the displaceability serves the purpose of adjusting the upper pass gap and the height of deposit of the material in the hopper itself.
  • the lower limitation of the gap may be provided by a sill which projects slightly above the plane of the table and somewhat raises the band, so that the band will be caused positively to bear over its entire width against the sill. Between sill and table slots are provided which allow particles carried along between band and table to fall through.
  • the sill itself may be made displaceable in height.
  • Figure 1 shows diagrammatically the side elevation of the applying device according to the invention.
  • Figure 2 shows to a larger scale the form of the deflecting edge according to the invention.
  • FIG. 3 is a detailed representation of the sill below the hopper and,
  • Figure 4 is a fragmental vertical sectional view showing the use of a roller at the delivery end of the conveyor.
  • the conveyance of the plate 10 is efiected in a known manner by a conveyor band or the like.
  • a conveyor band 11 Above the conveyor band 11 is the depositing device.
  • This conveyor band travels at the delivery end round a rigid edge 6, the point of which is slightly rounded, as will be seen from the illustration in Figure 2.
  • a thin roller 6a as illustrated in Figure 4 may also be used.
  • the radius of the roller or of the rounded edge is in the order of magnitude of about 0.2 mm.
  • the conveyor band 8 In the upper region, that is where the conveyance takes place, the conveyor band 8 is supported by a table 3.
  • Above the conveyor band 8 is a wall 12 which is adjustable in height and the lower edge of which forms a gap 4 with the conveyor band 8.
  • a supply chute or supply" surface 13 is provided, which extends to a certain length into” the hopper 5.
  • the result of this arrangement is, that below the supply chute 13 anempty space 14 is formed in the hopper; from the" length of the supply chute 13 extending into the hopper 5 and the angle of slope which forms from the endof the supplychute 13% to the wall of the hopper.
  • the supply chute may be made displaceable in its longitudinal direction.
  • the bottom limit of the gap 4 may be formed by a sill 9 which extends above the surface of the table 3" and provides that the band 8 will bear securely on the sill 9 (see Figure 3). Between the sill 9 and the table 3 passage slots may be provided.
  • the width of the gap 4 may be varied by raising or lowering the sill 9 by means of a rack 16 secured thereto and a rotatable toothed pinion 17 meshing therewith.
  • the table 3 it is also of great importance for the table 3 to be given a slight downward slope in the direction of conveyance. Such an incline in combination with thin bands further helps a uniform forward feed.
  • the carrying along of the powder in the gap is improved, because through the inclination the static friction on the band in opposition to the d rection of conveyance is increased.
  • the height of the material level is determined 4 possibility that moist powder may cause caking, when the device is set for very thin deposits. In such cases a simple or multiple sieve 15 arranged under the edge 6 or the roller 6a enables the lumps to be broken up, so that there will nevertheless be a good distribution.
  • Means for applying pulverulent substances. to metallic bases for the. purpose of plating comprising: a driving roller, a very thin and flexible conveyor band having upper and lower nuns. passing about the driving roller, a deflecting element havinga' v'erw small radius of curvature about which. the conveyor band also passes, a rigid table supporting the upper run of the conveyor band, the said table and the said upper. run; having a. slight downward inclination in the direction of conveyance, and a hopper immediately above the upper run of the conveyor band, so located that the upper run of the conveyor band itself forms the bottom of the hopper, and a narrow gap being left between the upper run of the conveyor band and the front wall. of the hopper.
  • Means for applyingpul'verulent substances to metallic bases as claimed in. claim 1, further comprising a Inngitudinally adjustable feed chute extending into and so far across the interior'of the hopper. as to limit thestatic pressure of the contents of'the hopper upon the material passing through the gap, the said static pressure being adjustable by longitudinal adjustment of the chute.
  • Means for applying pulverulent substances to metallic bases as claimed in claim 1, further comprising a second conveyor band at a lower level than the first-mentioned conveyor band, and said second conveyor band being adapted to carry along the metallic base to be plated underneath the deflecting element.
  • Means for applying pulverulent substances to metallic bases for the purpose of plating comprising: a driving roller, a very thin and flexible conveyor band having upper and lower runs passing. round the driving roller, a deflecting element of very small radius of curvature round which the conveyor band also passes, a rigid.
  • the rigid table supporting the upper run of the conveyor band, the said table and the said upper run having a slight downward inclination in the direction of conveyance, a hopper im mediately above the conveyor band, so arranged that the conveyor band itself forms the bottom of the hopper, and a narrow gap is left between the conveyor band and the front wall of the hopper, the rigid table being formed with a slot facing the lower edge of the front wall of the hopper, and an adjustable sill adapted to extend upwards through the said slot and to raise the conveyor band slightly at that portion if required, so as to vary the width of the gap between the conveyor band and the front wall of the hopper.
