Definitions

  • Abrasive sheets are available in many shapes and sizes, depending on the use for which they are intended. Some abrasive sheets are intended specifically for use with powered tools, for example rotary or orbital tools and, in that case, the shape of a sheet is determined by the particular tool with which it is to be used. Abrasive sheets in a range of standard shapes and sizes, suited to most standard powered tools, are readily available and are produced by die cutting continuous abrasive sheet material. Because large quantities of the standard shaped sheets are required, the die cutting operation can be carried out on a continuous basis using a rotary die cutter, and the subsequent handling and packing of the shaped sheets can be automated.
  • Disc-shaped sheets for example, are very commonly used for powered tools, and it is known to use a rotary die cutter to cut a plurality of individual discs or, alternatively, to cut chains of connected discs which can be wound onto a roll or folded up and packaged. See, for example, U.S. Patent No. 4,893,438. It is also known to provide dispensers for chains of connected abrasive articles and for non- connected abrasive articles provided on a continuous backing. See, for example, U.S. Patent Nos. 3,267,623 (Block); 3,849,949 (Steinhauser et al.); and 4,294,357 (Stevens et al.). Additionally, U.S. Patent No.
  • the array comprises a plurality of abrasive sheets arranged so as to have the narrow end of each sheet adjacent the narrow end of each adjacent abrasive sheet and so as to have the wide end of each sheet adjacent to the wide end of each adjacent sheet.
  • the array comprises four abrasive sheets forming a generally square array.
  • the array comprising five abrasive sheets forming a generally pentagonal array.
  • the array comprises six abrasive sheets forming a generally hexagonal array.
  • the dispenser comprises: a box configured to store the array of sheets, the box including a first wall having an opening therein for dispensing the array from inside the box to outside the box, the opening bounded by first and second opening edges; and abrasive sheet separating means mounted on the first wall, the separating means comprising a first separator edge oriented at a first edge angle relative to the first wall and a second separator edge oriented at a second edge angle relative to the first wall.
  • Figure 18 shows the array of Figure 17 in a spiral-wound roll
  • the arrays could be picked up pneumatically and transferred to a stacking location. It is, moreover, possible to use a rotary die cutter, rather than the flat bed cutter 7, to cut the sheet material 4, in which case the material 4 would move under the cutter continuously rather than in steps. It is also possible to laser cut the abrasive sheet array.
  • the term generally isosceles triangle is understood to include generally triangular shapes having a single line of symmetry, such as sheet 26 of Figure 13. Such generally isosceles triangles can include rounded corners as illustrated in Figure 1, rounded edges as illustrated in Figures 5 and 13, and faceted corners as illustrated in Figure 15.
  • abrasive sheet 40 is a generally equilateral triangle, it also includes second and third lines of symmetry 48 and 49.
  • the term generally equilateral triangle is understood to include generally triangular shapes having a three lines of symmetry. Such generally equilateral triangles can include rounded corners as illustrated in Figure 1, rounded edges as illustrated in Figures 5 and 13, and faceted corners as illustrated in Figure 15.
  • Abrasive sheet 40 also includes a narrow end 50 and a wide end 51 opposite from the narrow end. For a generally triangular abrasive sheet, three opposed pairs of narrow and wide ends can be defined.
  • the edge of the abrasive sheet at the first end 63 is oriented such that exposed edge (a) is at an angle ⁇ relative to the transverse axis 62 of the array 60.
  • exposed edge (a) is at an angle ⁇ relative to the transverse axis 62 of the array 60.
  • To remove the end sheet B it is necessary to separate the end sheet B from adjacent sheet C along edge (b). It is seen that edge (b) between adjacent sheets B and C is at angle ⁇ relative to the transverse axis 62.
  • To remove the next abrasive sheet C from the array 60 it is necessary to separate it from sheet D along edge (c). The next sheet D then separated along edge (d), and so on.
  • Abrasive sheet D is then separated form array 60 by pressing sheet D down against the separator 91 with edge (d) aligned with first separating edge 92, and so on. Opening 69 and separator 91 are wide enough to allow the abrasive sheet array 60 to be shifted back and forth so as to engage either separator edge 92, 93. In one preferred embodiment, slot 69 and separator 91 are approximately twice as wide as array 60.

Abstract

Selon l'invention, des ensembles de feuilles abrasives comprennent une pluralité de feuilles abrasives reliées l'une à l'autre et pouvant être facilement détachées l'une de l'autre. L'ensemble de feuilles abrasives est découpé dans un matériau abrasif sous forme de feuille, deux ou plusieurs ensembles de feuilles abrasives pouvant être découpés simultanément. Un ensemble de feuilles particulier a, en général, une forme hexagonale et comprend six feuilles généralement triangulaires qui sont reliées l'une à l'autre en des points isolés de sorte qu'elles peuvent être facilement détachées l'une de l'autre. L'invention concerne également un distributeur servant à stocker un ensemble de feuilles abrasives et à en distribuer les feuilles.
