Abstract
Abstract An apparatus for deflashing of elastomeric elements comprising: (a) a tumbling barrel having a closable opening for introducing and withdrawal of elastomeric elements and deflashing media to the interior of the barrel; (b) a refrigeration chamber sized for receiving the barrel therein, having an access opening for providing access to a barrel located therein, having mechanism for mounting the barrel therein, and having apparatus for lowering the temperature of the interior of the chamber; and (c) mechanism for imparting motion to the barrel mounted within the chamber to achieve impacting movement to the barrel contents. The apparatus avoids the high costs and dangers of the complicated prior art cryogenic devices and is excellently suited for smaller molders.
