Definitions

  • the present invention concerns a support for flexible or semi-rigid abrasive discs, particularly for the roughing and lapping of marble, stone, metals and similar, as well as abrasive discs comprising said support.
  • an abrasive disc of the above type comprises a support on which an abrasive granulate is applied by means of a resin coating.
  • the support is normally made of vulcanised vegetable fibre, entirely cellulose or with a cellulose base.
  • a strip is formed, composed of overlapping layers of cellulose or of paper with a cellulose base, between which are layers of adhesive are laid, until the desired thickness is obtained.
  • the strip thus obtained is pressed, dried and then rolled into reels.
  • the support is cut into the desired shape, onto which the adhesive and the abrasive are applied so as to obtain an abrasive disc.
  • the supports made in this way have various drawbacks.
  • the aim of the invention is to eliminate the aforesaid inconveniences, providing a support for abrasive discs which is inexpensive, simple to produce, maintains its shape and has a greater strength while having the same thickness as the traditional supports.
  • the support for abrasive discs according to the invention is obtained by moulding plastic material.
  • the plastics of which the support is composed is a particular polyamide (nylon) 66, reinforced with fibreglass.
  • the percentage of reinforcing fibreglass ranges normally from 20 to 50% and is advantageously 30%.
  • reference 1 indicates as a whole an abrasive disc for roughingor lapping marble, stone, metals and similar.
  • the disc 1 comprises a support 2 and a layer of abrasive material 3, applied on it with adhesive.
  • the disc 1 may be of a flexible or semi-rigid type, depending on the thickness of the support and of the abrasive layer, according to the use for which the disc is intended.
  • the embodiment illustrated is therefore purely an exemplary form of a disc, in which a certain convexity or crowning can be seen, that is a concave shaping of the side opposite the one on which the abrasive layer 3 is applied, as well as a central hole 4, for fitting the disc onto the chuck of the tool that is to rotate it in the operative phase.
  • the central part of the disc, around the hole 4 has a depression 5, with concave shaping opposite the aforesaid crowning, for better use.
  • the support 2 is obtained by moulding plastic.
  • the plastic used for the support 2 is polyamide 66, reinforced with fibreglass, in a percentage interval ranging from 20 to 50%.
  • the reinforcing fibreglass amounts to 30%.
  • polyamide 66 with 30% reinforcing fibreglass gives the best characteristics to the abrasive disc 1, in terms of consistency, with a same thickness, rigidity in use, removal capacity, resistance of the outline.
