ABSTRACT:
Dust collection apparatus for collecting dust during the grinding of tires includes a collection head mounted on the end of an arm, the collection head having a series of brushes which are arranged to contact the surface of the tire in proximity to where the grinding is taking place, in order to remove and trap the dust. Vacuum aspiration removes the trapped dust from the area surrounded by the brushes, and conveys it away for disposal, preferably via the arm, the arm being hollow for that purpose. The brushes are arranged such that all or substantially all of the tire surface which has been ground is subjected to the brushes. The dust collection apparatus is preferably attached to the arm which carries the grinding wheel used in the grinding machine, such that when the grinding wheel is moved into position against the tire, the dust collection apparatus moves with it, and is positioned against the tire. In some embodiments, the collection head pivots, so that it can stay properly positioned against the tire, regardless of the tire diameter. Four primary embodiments, all substantially identical in principle, each one for a separate application, namely: (1) full face grinding; (2) shoulder grinding; (3) on-center grinding; and (4) sidewall grinding
