Definitions

  • the present invention relates to the field of brushes intended for sanding and ginning machines, manual or industrial, in particular for wood, and relates to improvements to sanding and ginning brushes.
  • Brushes of this type currently existing generally consist of sheets of laminated abrasive cloth arranged perpendicular to the axis of rotation.
  • the efficiency of these brushes that is to say the duration of the abrasive in operation, hardly exceeds 50%, due to the fact that a large number of blades turn over and bear on the non-abrasive side.
  • the present invention aims to overcome these drawbacks.
  • the brush consists of intermediate rings having inclined parallel faces between which are laminated sheets of laminated fabric glued grain side on the rings, and by two end rings having a straight outer face and an inner face inclined in the same direction as the faces of the intermediate rings, all of these rings being clamped on a drive shaft.
  • the improvement to sanding and sanding brushes is characterized in that the brush consists of intermediate rings 1 having parallel inclined faces 2 between which sheets 3 of laminated fabric glued on the grain side are clamped on the rings 1, and by two end rings 4 and 5 having an inner face 2 'inclined in the same direction as the faces 2 of the rings 1, and an outer face 4 ′, 5 ′ straight, all of these rings being clamped on an axis drive not shown.
  • the sheets 3 of laminated canvas (FIG. 2) advantageously have the length of a half-circumference and are glued on the grain side on the internal diameter of the rings 1 (FIGS. 3 to 8) by forming two successive half-helices of opposite pitch (FIGS. 3 and 4), this assembly allowing the drive shaft not to be in contact with the grain, and thus not to wear out.
  • the width of the brush is adjustable as required by mounting or dismounting one or more intermediate rings 1.
  • the latter and the end rings 4 and 5 are advantageously made of pressure series polyvinyl chloride tube having good mechanical strength.
  • the arrangement of the sheets 3 on the rings 1, 4 and 5 allows that, in addition to the rotation, the slats are animated with a transverse movement producing on the workpiece a kind of crossed line.
  • the helical inclination of the sheets 3 allows the lamellae always to be on the right side, and a combination of three movements, namely, the advance of the part, the rotation of the brush, and its transverse displacement, allows the passage of the abrasive grain on all places, even the deepest, of a profile without whitening the edges.
  • the arrangement of the sheets 3 on the brush allows rotation of the latter in both directions by simple reversal of its axis, identification by a color which may indicate this possibility.
  • this brush can advantageously be used for sanding. of moldings in cabinetmaking, in the building, or other, in particular in continuous production lines, as well as for surface treatment of synthetic materials or metals.
