<p>A screen assembly 10 features adjacent pairs of first and second transverse members 14,15 movable towards and away from each other in a common plane. Between the transverse members 14,15 are held, flexible screening mats (12, fig.2) with apertures, flexation of the mats (12, fig.2) by the reciprocating movement of the transverse members 14,15 stopping the apertures in the mats 12 from blocking with material. The screen assembly 10 may be used as the bottom of two screen assemblies, may be retrofitted to existing arrangements, and may be more compact than previous flexible screening mat assemblies.</p> |
