Edge belt sander with swingable dust hood

摘要

A swingable dust hood is provided for use in the dust removal system of an endless belt type working machine. The dust hood has a jet air cleaner positioned on an inner wall which blows dust and other particles off the workpiece for exhaust via an outlet connected to the dust hood. A pivot rod is fixed to the outer shell of the dust hood and is rotatably journalled in a pivot receptacle bracketed to the machine support table. The hood can accordingly be positioned in three primary positions; namely, a first position wherein the hood completely encases a roll when the workpiece does not extend past the form platen; a second position wherein the hood partially encloses the piece when the workpiece is extended past the platen; and a third position wherein the hood is swung back to completely expose the drive roll to permit changing or repair of the endless belt and/or the roll.
