Abstract
A method and apparatus for testing rubber tires includes an abrader for rubbing against the surface of the tire and an eraser for removing particles of rubber left on the abrading surface by the tire. The eraser has the capability of absorbing oil or wax included in the tire being tested and in the particles deposited on the abrading surface.
Claims22
A method for testing rubber articles including tires, said rubber having oil or wax therein comprising the steps of:
- (a) providing an abrading surface;
- (b) imparting relative movement between said article and said abrading surface, wherein said abrading surface receives thereon particles of rubber having oil or wax;
- (c) providing an eraser having the capability of absorbing oil or wax;
- and
- (d) imparting relative movement between said eraser and said abrading surface to remove therefrom said particles and said oil or wax.
A method for testing a rubber article having oil or wax in the rubber formulation comprising the steps of:
- (a) providing an abrader;
- (b) imparting relative movement between said article and said abrader, said movement causing particles of rubber to adhere to said abrader;
- (c) separating at least a portion of said abrader from said article;
- (d) providing an eraser formed of a rubber having a formulation with substantially no oil or wax;
- (e) rubbing said eraser against said abrader to remove said particles.
Apparatus for testing rubber articles including tires comprising:
- (a) an abrading surface;
- (b) means for imparting relative movement between said article and said abrading surface;
- and
- (c) an eraser positioned to engage and be moved relative to said abrading surface, said eraser having the capability of absorbing oil or wax from said abrading surface.
Apparatus for testing a rubber tire comprising:
- (a) a rotatable wheel having an abrading surface with a substantially circular cross section;
- (b) means for rotating said rotatable wheel while said tire is engaged to said abrading surface;
- (c) an eraser engageable with said abrading surface while said abrading surface is being rotated;
- and
- (d) means for removing particles from said abrading surface after said tire is disengaged from said abrading surface and prior to being re-engaged therewith.
