Abstract
An abrasive elastic material composed of an abrasive fixedly bonded to an elastic substrate and the process for producing this material and conforming it into the various shapes needed for its use with power tools and the like. The material can be used on any of a wide variety of mechanical abrading devices, and has the advantages of conforming to irregular surfaces, resisting ripping and tearing, reducing vibration, allowing more subtlety in the application of pressure with the abrading surface and prolonged useful life. It differs from the material making up traditional abrading elements, such as honing belts, in its elasticity
Claims20
An elastic abrasive material for use in honing operations, said material comprising an abrasive surface affixed to an elastic substrate.
A method for producing elastic abrasive material suitable for cutting into various sizes and shapes to be used with a variety of power tools for the purpose of honing surfaces, said method comprising the steps of
- selecting a sheet of sandpaper having an abrasive side and a paper side,
- affixing said sandpaper to an elastic backing section such that said abrasive side is exposed and said paper side is adjacent to said elastic backing,
- treating said elastic backing section bearing said sandpaper so as to effect an improved bonding between said sandpaper and said elastic backing section,
- cutting said elastic backing section bearing said sandpaper into shapes suitable for use with said variety of power tools.
A method for producing an elastic honing belt for use with power tools, said method comprising the steps of
- (a) Selecting a mandrel having a mandrel breadth and a mandrel circumference;
- (b) Selecting an extended sheet of elastic material having an elastic length equal to said mandrel circumference and an elastic width equal to said mandrel breadth;
- (c) Applying a release agent to a surface of said mandrel;
- (d) Wrapping said elastic material around said mandrel and joining ends of said elastic material together in a seam by means of a chemical bonding agent and stitching tool;
- (e) Selecting a sheet of abrasive material with an abrasive width substantially equal to said elastic width and an abrasive length substantially equal to said elastic length, wherein said sheet of abrasive material has a paper backing side and an abrasive side;
- (f) Cleaning said paper backing side;
- (g) Applying a chemical bonding agent to said paper backing side;
- (h) Cutting said sheet of abrasive material into a plurality of strips of uniform width;
- (I) Applying a layer of chemical tactifying agent to said elastic material wrapped on said mandrel;
- (j) Applying said strips longitudinally along said elastic material wrapped on said mandrel;
- (k) Tightly wrapping said abrasive material with MYLAR sheeting and with nylon sheeting;
- (l) Placing said mandrel containing said strips into an enclosure, wherein said enclosure is then pressurized and heated to an elevated temperature for a predetermined time interval, after which said interval, said mandrel is removed from said enclosure;
- (m) Removing said MYLAR and nylon from said strips;
- (n) Loosening treated elastic material from said mandrel by injecting compressed air between said elastic material and said mandrel;
- (o) Removing treated said elastic material from said mandrel as a sleeve and cutting said sleeve into honing belts of desired width.
