MOULDED SCREEN PANEL AND APPARATUS AND METHOD OF MANUFACTURE

摘要

A moulded screen panel which is formed such that any flashing from the moulding is located at its upper screening surface and is thereby readily accessible for easy removal. The panel is formed of a series of equally spaced parallel ribs (24) and cross ribs (26) which define screening apertures (22). The upper surfaces (28) of ribs (24) define the screening surface (20). The upper surfaces (34) of the cross ribs (26) are located below the screening surface (20) such that grooves (36) are provided which extend across the screening surface (20). Dies for forming the mould close together at a surface of one die which provides the screening surface (20) such that any flashing is formed at that surface.
