Definitions

  • the present invention relates to brushes in general regardless the material used to manufacture the back portion (channel) or the material of filling bristles.
  • the present invention refers to a back portion of a brush of the spiral channel type.
  • Brushes have several applications the majority of them to clean, polish and treat sheets, plates, or strips of steel or any other material.
  • One particular type of brush is the spiral-channel type of brush. This brush is mainly manufactured to be installed around spiral shafts, thus forming cylindrical rolls of brushes. These brushes are called "Spiral-Channel Type Brushes”.
  • These brushes may be manufactured in a variety of dimensions, altering the diameter of the shaft in which the brush is mounted, the dimension of the metal channel (called back portion) wherein the bristles (cleaning wires) are inserted and, mainly, the length of the brushing bristle itself further to the length of the brush cylindrical roll.
  • the Spiral-Channel Type Brushes also have varying shapes and construction types of back portion, the most known made in "U" shape without cuts with wire in its internal part for installation of bristles.
  • the geometry of the back portion due to conformation, causes the wire to be fixed.
  • a second type pf back portion also known is a back portion having side openings, but without removal of material therefrom, the "remaining" pieces serve to help fixation of the wire.
  • a third type of back portion widely known is made with side openings, however, without wire but with a strip to fasten the bristles.
  • the present invention relates to a cylindrical roll of brush provided with the following construction: a brush roll comprising bristles inserted in a metal channel (back portion) spirally wound and this roll thus connected to a shaft.
  • the channel of present invention is a metal strip conformed having cuttings in the side portions.
  • the present invention comprises a metal channel D obtained by conforming by means of a mechanical process in a geometrical shape of a flat strip having spaced apart cuttings in the side portions of the strip of any shape evenly distributed or not in the side portion of the channel; the channel accommodating the bristles C fastened to the channel by means of wire; wherein after conforming, placing the bristles and fastening the same with wire to channel D, the channel D is spirally wound in the longitudinal direction of a shaft.
  • Figure 1 is a perspective view showing the back portion of brush D of the present invention having the strip (L, B) duly conformed in any shape (in the present invention "U" shape) having the bristles C fitted therein and fastened to the back portion by wire A.
  • Bristles C protrude the cuttings P being the same protruding with respect to the outer wall of back portion D.
  • the space between the coils of the brush, in particular in the side portion of the back portion between the cuttings P will be filled up by protruding bristles of the spiral of next back portion.
  • Figure 2 shows a section view of the brush roll showing the conformed strip spirally wound on shaft E, the cuttings P described above, the bristles indicated by letter C, the metal channel (the back portion) indicated by letter D and the shaft indicated by letter E.
  • FIG 4 it is shown a top view of the strip in flat format prior to being conformed by any conventional manufacturing process to be transformed into the channel (or back portion of brush) where it will be positioned the bristles to be fastened with wire.
  • the width of the strip is indicated by letter “B” and it will be determined by the final application, not being a limiting factor of present invention, the length is indicated by letter “L” and is not a limiting factor of present invention either.
  • the cuttings for projecting the bristles are indicated by letter P. Such cuttings P may have any desired shape without prejudice to the solution proposed by the invention. The dimensions of width and length will vary according to the application desired.
  • the channel is the housing for the bristles, and it is formed by a metal strip conformed in any geometrical shape, for example "U" shape, however, several shapes may be used to practice the invention and such shape is not a limiting factor of the invention; in general, such process occurs by means of rollers (discs having the shape to be conformed), thus the strip is forced to pass through several rollers having several shapes until the strip is in the desired shape.
  • the strip is conformed for the positioning of the bristles and allows that the same are well fastened.
  • a flat metal wire that passes through the interior of the channel. The wire is not released from the back portion due to the conformation applied to the channel (back portion).
  • the invention consists of the differential in the shape of the metal channel of the brush (back portion); the new profile of the same will allow a better distribution of the bristles and elongation of the life time of the brush.
