Abstract
A guard for use with a machine in which in operation a rotary element of the machine and a surface requiring an operation to be performed thereon are relatively displaced, comprises a first guard part secured to the machine so as to leave a gap between the guard part and the surface and a second guard part mounted on the first guard part by means permitting relative movement between the guard parts and in a manner to close the gap. To assist in the use of foam for dust suppression purposes, the mounting means for the second guard part on the first guard part defines a jacket having a fluid inlet opening and a fluid outlet opening adjacent the surface.
