Wood dust control has been inadequate for workers using wood shapers. An improved hood configuration was developed which could significantly reduce emission of wood dust particles. Under normal operating conditions, wood shaper emissions have been controlled by an exhaust hood located at the back edge of the work table, allowing the operator to move freely in the workplace. If the hood could be placed nearer the cutting head, dust collection would be maximized, but the operator's freedom to move in the work place would be severely restricted. A hood extension has been designed which has a flexible face opening. The flexible face consisted of cloth covered chains that allow the wood to pass through, but which at the same time stop the wood dust particles from moving through. The extension also increases the hood face velocity by minimizing the open face area. At the present time this wood dust control device is not commercially available.
