Definitions

  • ABSTRACT A string of brick material is extruded, and at least one surface of the string is engaged with one or more rollers having surface projections, to form depressions in the string surface.
  • An instrument such as a smoothsurfaced roller, is then applied to the depressionbearing surface, there being relative movement between the surface and instrument in a direction generally parallel to the surface.
  • the depressions are deformed, giving the surface the appearance of a hand-molded brick.
  • the string is cut into individual bricks.
  • a filler may be introduced into the depressions prior to their deformation.
  • the upper edges of the extruded string may be rounded, and the upper cut edges of the bricks may be deformed by the tool which cuts the string into individual bricks.
  • 6 Claims, 6 Drawing Figures 1 APPARATUS FOR THE MANUFACTURE OF BRICKS cally relates to such a method'and apparatus employing a profile roller for producing deformations in a surface of the string of brick material leaving the extrusion press, which surface may or may;not be sanded.
  • Machine bricks which are made on extrusion presses and necessarily have-a uniform surface'texture
  • Hand-molded bricks which are'thrown by hand into box molds and thereby acquire very individual surface characteristics.
  • Underlying the invention is'the' problem of producing machine clinker bricks which cannot be distinguished from hand-molded bricks, even by specialists.
  • a further feature of the invention involves'introducing sand, sawdust, or other filler material into the surface deformations, with the aid-of a broom, prior to the milling step to produce various types of undercuts in the brick material surface.
  • FIG. 1 is a side view of the entire apparatus
  • FIG. 2 is a plan view of the entire apparatus
  • FIG. 3 is a section through the extruded string along the line III-IlI of FIG. 1;
  • FIG. 4 is a section along the line lVlV of FIG. 1;
  • FIG. 5 is a section along the line V-V of FIG. 4, with cutting bow lowered;
  • FIG. 6 is a perspective view of the various rollers of the apparatus.
  • the clay string 12 densely sanded according to known procedure, leaves the extrusion press 10 in the fonn 14 shown in FIG. 3, with rounded upper edges 16, which is obtained by corresponding choice of the mouthpiece of the extrusion press.
  • This form is expedient so that the clay string can absorb the considerable pressures of the rollers which will act on it, and press it into the rectangular form. These rollers would severely deform the usual rectangular string.
  • the clay string while still in a plastic state, is moved longitudinally and at least one profiled roller acts on the upper surface of the string. Further, at least one pair of profile rollers can treat the side surfaces.
  • the diameters of therollers, their surface structure, the pressure on the string, and their position with respect to the string can be adapted to the particular requirements.
  • the rollers 18 and 20 are used for the treatment of the upper surface of the string.
  • the large roller 18 with its coarse surface projections, giving it a pronounced relief-type surface texture makes deep scarsand gashes, in the string surface.
  • the smaller roller 20 produces numerous shallower desurface structure, in large quantities much more' cheaply than hand-molded bricks.
  • the apparatus required by the invention can easily be installed on already existing fabrication apparatus including an extrusion press.
  • any type of brick form can be used with the present invention by variation of the extrusion nozzles of the extrusion press, such as those developed for reasons of heat-insulation and saving of pressions.
  • a filler such as, hay, sand, or'sawdust, which is then swept with a broom 24 into the cuts and depressions.
  • the particular filler used causes different surface textures to be produced.
  • a'suitable instrument is used to apply a moving pressure to the surface, the direction of movement being generally parallel to the surface.
  • the instrument used is a small smooth roller 26, although a scraper or other device could also be used.
  • the string moves beneath roller 26, and the high contact pressure between the upper depression-bearing surface and the roller causes the depressions to be deformed, thereby producing oblique cuts and undercuts in the string surface, this surface formation being typically found in hand-molded bricks.
  • the side surfaces of the string can be treated in a similar manner, for which purpose in the present example two roller pairs 28 and 30 are employed.
  • a further characteristic feature of hand-molded bricks are the rounded upper edges yielded by the manner of production.
  • To form these roundings there is mounted on the bow 34 of the automatic cutter 32, which cuts up the string into pieces 36 of any desired thickness, a strip 38 which extends in a downward curve into a sharp edge .40, as can be seen in FIG. 5.
  • the height of the edge 40 can be adjusted by shifting and fastening the strip 38 using the screw 42 to conform to the particular height of the string or of the bricks.
  • each brick is formed with rounded side edges.
  • An apparatus for producing bricks each having at least one surface resembling that of a hand-molded brick comprising:
  • an extruder for extruding a string of brick material means forming part of said extruder for rounding the top surface of said string;
  • said cutting means including means spaced from the cutting edge for rounding off the cut upper edges of the individual bricks, and means for adjusting the spacing between the cutting edge and said rounding off means, and
  • an instrument between said roller and cutting means for applying a pressure against the depression-bearing surface of the moving string to deform the surface depressions and flatten the rounded top surface.
  • said cutting means includes a bow, and a cutting element extending across said bow and having a cutting edge
  • said rounding-off means includes a strip extending across said bow at a level above said cutting edge, and including means for adjusting the spacing between said strip and cutting edge.
