Definitions

  • the invention relates to a machine for pointing ceramic tiles or the like slabs such as mosaics, concrete slabs, natural stone or marble coverings for floors or walls.
  • the machine comprises a plate rotated at a speed of between and l revolutions per minute.
  • the underside of the plate being provided with resilient slanted readily exchangeable steel blades of equal size which are spread evenly over approximately sector-shaped areas of the plate and which are completely covered on the side facing the'material to be processed with pads of-moistuw absorbent material wetted before use and having a thickness of from 5 to [5 mm.
  • An advantage of the machine resides in avoidance of tedious'manual work and in-enabling the pointing to be car ried out eaily and quickly by a person in an upright'position.
  • the cement'sludge is pushed by the pads into thejoints until they are filled completely and a continuous flush connecting surface is obtained between adjacent slabs.
  • the pads will preferably be of Merino felt which is durable and has good absorption properties. Abrading and washing down the joints and also the slab surfacesis effected in the same way by levigating the filling cement with the Merino felt pads on the underside of the jointing wheel driven preferably electri- --cally at a low speed, which produces an even spreading of the filling material.
  • the Merino felt pads ensure that the cement sludge is well distributed.
  • the steel blades may be arranged singly or in groups to form a multiple lamina for additional resilience.
  • FIGS. 1 and 2 are plan views from below of plates each fitted with [5 blades (those in FIG. 1 being double-ply) having felt pads secured thereto suitable for pointing wall coverings;
  • FIG. 3 is a section through a plate taken on the lines A4! of 70 FIGS. 1 and 2;
  • FIG. 4 is a perspective view of a pointing machine. the plate of which is fitted with 10 blades (double-ply) and 5 felt pads and is provided with 2 handles for use when pointing wall coverings; and
  • FIG. 5 and 6 show a single plate pointing machine suitable for use on floor coverings.
  • the plate having a diameter of 600 mm. is fitted on the underside with 80 steel strip blades (double-ply) and 40 Merino felt pads covering the working surface of the lamina blades.
  • Merino felt pads 3 are provided with a thickness of about 10 mm. and intended in the operable position of the apparatus for positioning against working surface 1 and more especially joints 2.
  • the pads 3 are resiliently held at even pressure on single or multiple super-line steel strip blades 4 (in the latter case the plates have large diameters).
  • the pads 3 are firmly secured but readily exchangeable by being detachably screwed to the underside of the plate 5 in inclined position opposite the actual working edge. Securing screws are denoted by 6 and the drive is preferably effected by means of an electric motor.
  • the housing 7 of which, as shown in FIG. 4. is provided with two handles 8 extending at right angles and radially thereto for pointing wall coverings. The machine as shown in FIG.
  • a vertically pivotal guide rod 9 with a crossbar 10 is also provided for manipulating the fixed portion and a cable I I which is laid in the guide rod 9 supplies current to the electric motor accommodated in the housing 7, which motor in turn drives the plate 5 via a reduction gear (not shown).
  • the speed of both the small plate 5, having a diameter of 220 or 300 mm., and the larger plate is relatively low, i.e. between and H0 revolutions per minute which is made possible by the'already mentioned reduction gear which is arranged between the driving shaft of the electric motor and the plate shaft.
  • the new pointing machine according to the invention does not require the operator to kneel and hence is no longer injurious to health.
  • the work output is considerablyincreased compared with that obtainable by manipulating a long knifelike or slightly curved pointing trowel which does not facilitate the production of nonporous sealed joints having a smooth surface.
  • All the necessary operations such as pressing the cement sludge deeply into the joints without leaving cavities or pores, abrading the surfaces of the joints and slabs and subsequently washing the smooth surfaces of the joints and slabs by means of wet wood powder for cleaning, are performed by the new pointing machine by means of oneand the same plate.
  • the work output may easily be about 150 in per hour.
  • a machine for pointing ceramic tiles or the like, to per fonn operations such as filling joints, leveling surfaces of the joints, and washing the surfaces ofthe joints and tiles comprising drive means and associated shaft for rotation of a plate at a speed of between 55 and 110 revolutions per minute, the
  • underside of said plate being provided with resilient slanted readily exchangeable steel blades of equal size which are evenly located over approximately sector-shaped areas of said plate and which are completely covered on the side facing the material to be processed with pads of moisture-absorbent material wetted before use and having a thickness of from 5 to 15 mm.
  • a pointing machine wherein said plates are provided with at least single lamina steel blades on the underside of said revolving plate whilst said pads are fitted singly; smaller plates suitable for pointing wall coverings having an outer diameterof 220 mm., are fitted with five felt pads and I0 steel strip blades arranged in pairs; those having a diameter of 350 mm. are fitted with 10 felt pads and 30steel blades arranged in groups of three, whilst larger plates intended for pointing floor coverings with a diameter of 600 mm. are provided with 40 pads and steel blades arranged in pairs.
  • a pointing machine according to claim 1, wherein the inclination of the readily exchangeable blades is variable.
  • a pointing machine according to claim 1, wherein said blades and pads are so distributed in the approximately sectorshaped areas of the plate on which they are retained that a diminishing number of annular sector sections are provided from the outer circumference to the 'plate center which belong to the given ranges of radii to obtain an even wearing.
