Abstract
A shot blast machine for deflashing plastic molded parts in which a substantially horizontal conveyor belt is used for delivering the parts to be deflashed. Shot blasting wheels are located above the conveyor belt and impel particles downward into deflashing engagement with plastic parts on the conveyor. A wire mesh member, in the form of an endless belt, is positioned above and in close proximity to the conveyor belt so that parts being blasted are trapped and held between the wire mesh belt and the conveyor belt. The wire mesh belt prevents the parts being deflashed from being moved off the conveyor belt under the influence of blasting particles. The hold down belt is also movably mounted above the conveyor belt so that it can float up and down and accommodate parts of different sizes.
