Abstract
An exhaust shroud adapted for mounting on the casing of a portable sanding machine is provided with a resiliently deformable lip arranged to engage with a surface of a driven sanding member or workpiece outwardly of such member in such a manner as to provide for an effectively controlled, vacuum induced flow of dust generated by a sanding operation into the shroud, while at the same time not producing a vacuum induced braking effect on movements of the sanding member or movements of the machine relative to the workpiece.
